impact development technology for reducing stormwater runoff in the construction of sponge city. At present, it is difficult to perform the automatic control of SST for reducing peak flow. In this paper, fuzzy control was introduced into the peak control of SST to improve the efficiency of reducing stormwater runoff. Firstly, the design of SST was investigated. A catchment area and a return period were assumed, a SST model was manufactured, and then the storage capacity of the SST was verified. Secondly, the control parameters of the SST based on reducing stormwater runoff were analyzed, and a schematic diagram of real-time control (RTC) system based on peak control SST was established. Finally, fuzzy control system of a double input (flow and water level) and double output (inlet and outlet valve) was designed. The results showed that 1) under the different return periods (one year, three years, five years), the SST had the effect of delayed peak control and storage by increasing the detention time, 2) rainfall, pipeline flow, the influent time and the water level in the SST could be used as RTC parameters, and 3) the response curves of flow velocity and water level fluctuated very little and reached equilibrium in a short time. The combination of online monitoring and fuzzy control was feasible to control the SST automatically. This paper provides a theoretical reference for reducing stormwater runoff and improving the operation efficiency of SST. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stormwater%20runoff" title="stormwater runoff">stormwater runoff</a>, <a href="https://publications.waset.org/abstracts/search?q=stormwater%20storage%20tank" title=" stormwater storage tank"> stormwater storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20control" title=" real-time control"> real-time control</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20control" title=" fuzzy control"> fuzzy control</a> </p> <a href="https://publications.waset.org/abstracts/82758/a-fuzzy-control-system-for-reducing-urban-stormwater-runoff-by-a-stormwater-storage-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82758.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">202</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2403</span> Liquid Sulphur Storage Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roya%20Moradifar">Roya Moradifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Naser%20Agharezaee"> Naser Agharezaee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper corrosion in the liquid sulphur storage tank at South pars gas complex phases 2&3 is presented. This full hot insulated field-erected storage tanks are used for the temporary storage of 1800m3 of molten sulphur. Sever corrosion inside the tank roof was observed during over haul inspections, in the direction of roof gradient. Investigation shown, in spite of other parts of tank there was no insulation around these manholes. Internal steam coils do not maintain a sufficiently high tank roof temperature in the vapor space. Sulphur and formation of liquid water at cool metal surface, this combination leads to the formation of iron sulfide. By employing a distributed external heating system, the temperatures of any point of the tank roof should be based on ambient dew point and the liquid storage solidification point. Also other construction and operation of tank is more important.

Also, the number of petroleum tank fires is oscillating between 15 and 20 fires per year. About 33% of all tank fires are attributed to lightning. Floating roof tanks (FRT’s) are especially vulnerable to lightning. To minimize the likelihood of a fire, the API RP 545 recommends three major modifications to floating roof tanks. This paper was inspired by a stroke of lightning that ignited a fire in a crude oil storage tank belonging to an Egyptian oil company, and is aimed at providing an efficient lightning protection system to the tank under study, in order to avoid the occurrence of such phenomena in the future and also, to give valuable recommendations to be applied to floating roof tank projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crude%20oil" title="crude oil">crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=floating%20roof%20tank" title=" floating roof tank"> floating roof tank</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20protection%20system" title=" lightning protection system"> lightning protection system</a> </p> <a href="https://publications.waset.org/abstracts/67175/protection-of-floating-roof-petroleum-storage-tanks-against-lightning-strokes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67175.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">282</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2400</span> Thermal Analysis and Experimental Procedure of Integrated Phase Change Material in a Storage Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chargui%20Ridha">Chargui Ridha</a>, <a href="https://publications.waset.org/abstracts/search?q=Agrebi%20Sameh"> Agrebi Sameh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The integration of phase change materials (PCM) for the storage of thermal energy during the period of sunshine before being released during the night is a complement of free energy to improve the system formed by a solar collector, tank storage, and a heat exchanger. This paper is dedicated to the design of a thermal storage tank based on a PCM-based heat exchanger. The work is divided into two parts: an experimental part using paraffin as PCM was carried out within the Laboratory of Thermal Processes of Borj Cedria in order to improve the performance of the system formed by the coupling of a flat solar collector and a thermal storage tank and to subsequently determine the influence of PCM on the whole system. This phase is based on the measurement instrumentation, namely, a differential scanning calorimeter (DSC) and the thermal analyzer (hot disk: HOT DISK) in order to determine the physical properties of the paraffin (PCM), which has been chosen. The second phase involves the detailed design of the PCM heat exchanger, which is incorporated into a thermal storage tank and coupled with a solar air collector installed at the Research and Technology Centre of Energy (CRTEn). A numerical part based on the TRANSYS and Fluent software, as well as the finite volume method, was carried out for the storage reservoir systems in order to determine the temperature distribution in each chosen system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20change%20materials" title="phase change materials">phase change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20tank" title=" storage tank"> storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger" title=" heat exchanger"> heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20plate%20collector" title=" flat plate collector"> flat plate collector</a> </p> <a href="https://publications.waset.org/abstracts/157898/thermal-analysis-and-experimental-procedure-of-integrated-phase-change-material-in-a-storage-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157898.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2399</span> Foundation Retrofitting of Storage Tank under Seismic Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhasan%20Naeini">Seyed Abolhasan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Hossein%20Zade"> Mohammad Hossein Zade</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20Izadi"> E.

Uplifting and excessive settlement due to liquid sloshing are the most frequent damages in cylindrical liquid tanks after shell bucking failure modes. As a matter of fact, uses of liquid storage tanks because of the simple construction on compact layer of soil as a foundation are very conventional, but in some cases need to retrofit are essential. The tank seismic behavior can be improved by modifying dynamic characteristic of tank with verifying seismic loads as well as retrofitting and improving base ground. This paper focuses on a typical steel tank on loose, medium and stiff sandy soil and describes an evaluation of displacement of the tank before and after retrofitting. The Abaqus program was selected for its ability to include shell and structural steel elements, soil-structure interaction, and geometrical nonlinearities and contact type elements. The result shows considerable decreasing in settlement and uplifting in the case of retrofitted tank. Also, by increasing shear strength parameter of soil, the performance of the liquid storage tank under the case of seismic load increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel%20tank" title="steel tank">steel tank</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-structure" title=" soil-structure"> soil-structure</a>, <a href="https://publications.waset.org/abstracts/search?q=sandy%20soil" title=" sandy soil"> sandy soil</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20load" title=" seismic load"> seismic load</a> </p> <a href="https://publications.waset.org/abstracts/48342/foundation-retrofitting-of-storage-tank-under-seismic-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2398</span> Rock-Bed Thermocline Storage: A Numerical Analysis of Granular Bed Behavior and Interaction with Storage Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nahia%20H.%20Sassine">Nahia H.

Packed bed TES can be considered as a cost–effective solution in concentrated solar power plants (CSP). Such a device is made up of a tank filled with a granular bed through which heat-transfer fluid circulates. However, in such devices, the tank might be subjected to catastrophic failure induced by a mechanical phenomenon known as thermal ratcheting. Thermal stresses are accumulated during cycles of loading and unloading until the failure happens. For instance, when rocks are used as storage material, the tank wall expands more than the solid medium during charge process, a gap is created between the rocks and tank walls and the filler material settles down to fill it. During discharge, the tank contracts against the bed, resulting in thermal stresses that may exceed the wall tank yield stress and generate plastic deformation. This phenomenon is repeated over the cycles and the tank will be slowly ratcheted outward until it fails. This paper aims at studying the evolution of tank wall stresses over granular bed thermal cycles, taking into account both thermal and mechanical loads, with a numerical model based on the discrete element method (DEM). Simulations were performed to study two different thermal configurations: (i) the tank is heated homogeneously along its height or (ii) with a vertical gradient of temperature. Then, the resulting loading stresses applied on the tank are compared as well the response of the internal granular material. Besides the study of the influence of different thermal configurations on the storage tank response, other parameters are varied, such as the internal angle of friction of the granular material, the dispersion of particles diameters as well as the tank’s dimensions. Then, their influences on the kinematics of the granular bed submitted to thermal cycles are highlighted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discrete%20element%20method%20%28DEM%29" title="discrete element method (DEM)">discrete element method (DEM)</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20cycles" title=" thermal cycles"> thermal cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20energy%20storage" title=" thermal energy storage"> thermal energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=thermocline" title=" thermocline"> thermocline</a> </p> <a href="https://publications.waset.org/abstracts/58772/rock-bed-thermocline-storage-a-numerical-analysis-of-granular-bed-behavior-and-interaction-with-storage-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58772.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2397</span> Coupling Heat Transfer by Natural Convection and Thermal Radiation in a Storage Tank of LNG</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Hariti">R.

Throughout history, China had many excellent experiences dealing with the flood, and can be used as a significant reference for contemporary urban construction. In view of this, the research used the method of literature analysis to find out the main water storage measures in ancient cities, including reservoir storage and pond water storage. And it used the case study method to introduce the historical evolution, engineering measures and landscape design of 4 typical ancient Chinese cities in details. Then we found the pond and the reservoir were the main infrastructures for the ancient Chinese city to avoid the waterlogging and flood. At last this paper summed up the historical experience of Chinese traditional water storage and made conclusions that the establishment of a reasonable green water storage facilities could be used to solve today's rain and flood problems, and hoped to give some enlightenment of stormwater management to our modern city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ancient%20Chinese%20cities" title="ancient Chinese cities">ancient Chinese cities</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20storage%20project" title=" water storage project"> water storage project</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20classical%20gardening" title=" Chinese classical gardening"> Chinese classical gardening</a>, <a href="https://publications.waset.org/abstracts/search?q=stormwater%20management" title=" stormwater management"> stormwater management</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20facilities" title=" green facilities"> green facilities</a> </p> <a href="https://publications.waset.org/abstracts/70823/preliminary-study-on-chinese-traditional-garden-making-based-on-water-storage-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70823.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2394</span> The Pressure Distribution on the Rectangular and Trapezoidal Storage Tanks' Perimeters Due to Liquid Sloshing Impact</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Saghi">Hassan Saghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholam%20Reza%20Askarzadeh%20Garmroud"> Gholam Reza Askarzadeh Garmroud</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Ali%20Reza%20Emamian"> Seyyed Ali Reza Emamian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sloshing phenomenon is a complicated free surface flow problem that increases the dynamic pressure on the sidewalls and the bottom of the storage tanks. When the storage tanks are partially filled, it is essential to be able to evaluate the fluid dynamic loads on the tank’s perimeter. In this paper, a numerical code was developed to determine the pressure distribution on the rectangular and trapezoidal storage tanks’ perimeters due to liquid sloshing impact. Assuming the fluid to be inviscid, the Laplace equation and the nonlinear free surface boundary conditions are solved using coupled BEM-FEM. The code performance for sloshing modeling is validated against available data. Finally, this code is used for partially filled rectangular and trapezoidal storage tanks and the pressure distribution on the tanks’ perimeters due to liquid sloshing impact is estimated. The results show that the maximum pressure on the perimeter of the rectangular and trapezoidal storage tanks was decreased along the sidewalls from the top to the bottom. Furthermore, the period of the pressure distribution is different for different points on the tank’s perimeter and it is bigger in the trapezoidal tanks compared to the rectangular ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pressure%20distribution" title="pressure distribution">pressure distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20sloshing%20impact" title=" liquid sloshing impact"> liquid sloshing impact</a>, <a href="https://publications.waset.org/abstracts/search?q=sway%20motion" title=" sway motion"> sway motion</a>, <a href="https://publications.waset.org/abstracts/search?q=trapezoidal%20storage%20tank" title=" trapezoidal storage tank"> trapezoidal storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20BEM-FEM" title=" coupled BEM-FEM"> coupled BEM-FEM</a> </p> <a href="https://publications.waset.org/abstracts/20717/the-pressure-distribution-on-the-rectangular-and-trapezoidal-storage-tanks-perimeters-due-to-liquid-sloshing-impact" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20717.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">551</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2393</span> Mecano-Reliability Approach Applied to a Water Storage Tank Placed on Ground</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amar%20Aliche">Amar Aliche</a>, <a href="https://publications.waset.org/abstracts/search?q=Hocine%20Hammoum"> Hocine Hammoum</a>, <a href="https://publications.waset.org/abstracts/search?q=Karima%20Bouzelha"> Karima Bouzelha</a>, <a href="https://publications.waset.org/abstracts/search?q=Arezki%20Ben%20Abderrahmane"> Arezki Ben Abderrahmane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditionally, the dimensioning of storage tanks is conducted with a deterministic approach based on partial coefficients of safety. These coefficients are applied to take into account the uncertainties related to hazards on properties of materials used and applied loads. However, the use of these safety factors in the design process does not assure an optimal and reliable solution and can sometimes lead to a lack of robustness of the structure. The reliability theory based on a probabilistic formulation of constructions safety can respond in an adapted manner. It allows constructing a modelling in which uncertain data are represented by random variables, and therefore allows a better appreciation of safety margins with confidence indicators. The work presented in this paper consists of a mecano-reliability analysis of a concrete storage tank placed on ground. The classical method of Monte Carlo simulation is used to evaluate the failure probability of concrete tank by considering the seismic acceleration as random variable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20approach" title="reliability approach">reliability approach</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20tanks" title=" storage tanks"> storage tanks</a>, <a href="https://publications.waset.org/abstracts/search?q=monte%20carlo%20simulation" title=" monte carlo simulation"> monte carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20acceleration" title=" seismic acceleration"> seismic acceleration</a> </p> <a href="https://publications.waset.org/abstracts/46607/mecano-reliability-approach-applied-to-a-water-storage-tank-placed-on-ground" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46607.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2392</span> Influence of the Non-Uniform Distribution of Filler Porosity on the Thermal Performance of Sensible Heat Thermocline Storage Tanks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuchao%20Hua">Yuchao Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Lingai%20Luo"> Lingai Luo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thermal energy storage is of critical importance for the highly-efficient utilization of renewable energy sources. Over the past decades, single-tank thermocline technology has attracted much attention owing to its high cost-effectiveness. In the present work, we investigate the influence of the filler porosity’s non-uniform distribution on the thermal performance of the packed-bed sensible heat thermocline storage tanks on the basis of the analytical model obtained by the Laplace transform. It is found that when the total amount of filler materials (i.e., the integration of porosity) is fixed, the different porosity distributions can result in the significantly-different behaviors of outlet temperature and thus the varied charging and discharging efficiencies. Our results indicate that a non-uniform distribution of the fillers with the proper design can improve the heat storage performance without changing the total amount of the filling materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title="energy storage">energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20thermocline%20storage%20tank" title=" heat thermocline storage tank"> heat thermocline storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=packed%20bed" title=" packed bed"> packed bed</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20thermal%20analysis" title=" transient thermal analysis"> transient thermal analysis</a> </p> <a href="https://publications.waset.org/abstracts/149548/influence-of-the-non-uniform-distribution-of-filler-porosity-on-the-thermal-performance-of-sensible-heat-thermocline-storage-tanks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149548.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2391</span> Behavior of an Elevated Liquid Storage Tank under Near-Fault Earthquakes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koushik%20Roy">Koushik Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sourav%20Gur"> Sourav Gur</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudib%20K.%20Mishra"> Sudib K.

Studies in the recent past explore the effects of pulse type ground motion on the special structures, such as transmission towers in view of their high flexibility. Identically, long period sloshing of liquid in the storage tanks under dynamic loading might increase their failure vulnerability under near-fault pulses. Therefore, the behavior of the elevated liquid storage tank is taken up in this study. Simple lumped mass model is considered, with the bilinear force-deformation hysteresis behavior. Set of near-fault seismic ground acceleration time histories are adopted for this purpose, along with the far-field records for comparison. It has been demonstrated that pulse type motions lead to significant increase of the responses; in particular, sloshing of the fluid mass could be as high as 5 times, then the far field counterpart. For identical storage capacity, slender tanks are found to be more vulnerable than the broad ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=far-field%20motion" title="far-field motion">far-field motion</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis" title=" hysteresis"> hysteresis</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20storage%20tank" title=" liquid storage tank"> liquid storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=near%20fault%20earthquake" title=" near fault earthquake"> near fault earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=sloshing" title=" sloshing"> sloshing</a> </p> <a href="https://publications.waset.org/abstracts/63452/behavior-of-an-elevated-liquid-storage-tank-under-near-fault-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63452.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2390</span> Welding Process Selection for Storage Tank by Integrated Data Envelopment Analysis and Fuzzy Credibility Constrained Programming Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahmad%20Wisnu%20Wardana">Rahmad Wisnu Wardana</a>, <a href="https://publications.waset.org/abstracts/search?q=Eakachai%20Warinsiriruk"> Eakachai Warinsiriruk</a>, <a href="https://publications.waset.org/abstracts/search?q=Sutep%20Joy-A-Ka"> Sutep Joy-A-Ka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Selecting the most suitable welding process usually depends on experiences or common application in similar companies.

This paper perceived the value engineering (VE) approach applied in infrastructure works, namely stormwater drainage. This method is adopted in line as consultants have completed the detailed design. Function Analysis System Technique (FAST) diagram and VE job plan, information, function analysis, creative judgement, development, and recommendation phase are used to scrutinize the initial design of stormwater drainage. An estimated cost reduction using the VE approach of 2% over the initial proposal was obtained. This cost reduction is obtained from the design optimization of the drainage foundation and structural system, where the pile design and drainage base structure are optimized. Likewise, the design of the on-site detention tank (OSD) pump was revised and contribute to the cost reduction obtained. This case study shows that the VE approach can be an important tool in optimizing the design to reduce costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=value%20engineering" title="value engineering">value engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=function%20analysis%20system%20technique" title=" function analysis system technique"> function analysis system technique</a>, <a href="https://publications.waset.org/abstracts/search?q=stormwater%20drainage" title=" stormwater drainage"> stormwater drainage</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20reduction" title=" cost reduction"> cost reduction</a> </p> <a href="https://publications.waset.org/abstracts/122180/value-engineering-and-its-impact-on-drainage-design-optimization-for-penang-international-airport-expansion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122180.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2388</span> Effect of Operating Conditions on the Process Hydrogen Storage in Metal Hydride</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Babou">A.

Buncefield, Jaipur, Puerto Rico, and West Virginia are just a few accidents with catastrophic consequences. Thus, it is very important for any industry to take the right safety measures for overfill prevention. Moreover, one of the main causative factors in the overfill accidents was inadequate risk analysis and, subsequently, inadequate design. This study aims to provide a full assessment in accordance with the Functional safety standard: “IEC 615 11 – Safety instrumented systems for the process industry” to the tank overfill scenario according to the standard’s Safety Life Cycle (SLC), which includes: the analysis phase, the implementation phase, and the operation phase. The paper discusses in depth the tank overfills Independent Protection Layers (IPLs) with systematic analysis to avoid the safety risks of under-design and the financial risk of facility overdesign. The result shows a clear and systematic assessment in compliance with the standards that can help to assist existing tank overfilling setup or a guide to support designing new storage facilities overfill protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IEC%2061511" title="IEC 61511">IEC 61511</a>, <a href="https://publications.waset.org/abstracts/search?q=PHA" title=" PHA"> PHA</a>, <a href="https://publications.waset.org/abstracts/search?q=LOPA" title=" LOPA"> LOPA</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20safety" title=" process safety"> process safety</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20instrumented%20systems" title=" safety instrumented systems"> safety instrumented systems</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20instrumented%20function" title=" safety instrumented function"> safety instrumented function</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20safety" title=" functional safety"> functional safety</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20life%20cycle" title=" safety life cycle"> safety life cycle</a> </p> <a href="https://publications.waset.org/abstracts/160747/storage-tank-overfill-protection-in-compliance-with-functional-safety-standard-iec-61511" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2386</span> Analysis of Evaporation of Liquid Ammonia in a Vertical Cylindrical Storage Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Chikh">S.

Numerical simulation is carried out by solving the governing equations namely, continuity, momentum, energy, and diffusion of species. The effect of temperature of surrounding air, the filling speed of the reservoir and the temperature of the filling liquid ammonia on the evaporation rate is investigated. Results show that the temperature of the filling liquid has little effect on the liquid ammonia for a short period, which, in fact, is function of the filling speed. The evaporation rate along the free surface of the liquid is non-uniform. The inlet temperature affects the vapor ammonia temperature because of pressure increase. The temperature of the surrounding air affects the temperature of the vapor phase rather than the liquid phase. The maximum of evaporation is reached at the final step of filling. In order to minimize loss of ammonia vapors automatically causing losses in quantity of the liquid stored, it is suggested to ensure the proper insulation for the walls and roof of the reservoir and to increase the filling speed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evaporation" title="evaporation">evaporation</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20ammonia" title=" liquid ammonia"> liquid ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20tank" title=" storage tank"> storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/49166/analysis-of-evaporation-of-liquid-ammonia-in-a-vertical-cylindrical-storage-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49166.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">288</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2385</span> 3D Modeling of Flow and Sediment Transport in Tanks with the Influence of Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Terfous">A.

One key aspect is to propose optimized designs for detention tanks in order to best reduce flood peak flows and in the meantime settle particles. It is, therefore, necessary to understand complex flows patterns and sediment deposition conditions in stormwater detention basins. The aim of this paper is to study flow structure and particle deposition pattern for a given tank geometry in view to control and maximize sediment deposition. Both numerical simulation and experimental works were done to investigate the flow and sediment distribution in a storm tank with a cavity. As it can be indicated, the settle distribution of the particle in a rectangular tank is mainly determined by the flow patterns and the bed shear stress. The flow patterns in a rectangular tank differ with different geometry, entrance flow rate and the water depth. With the changing of flow patterns, the bed shear stress will change respectively, which also play an influence on the particle settling. The accumulation of the particle in the bed changes the conditions at the bottom, which is ignored in the investigations, however it worth much more attention, the influence of the accumulation of the particle on the sedimentation should be important. The approach presented here is based on the resolution of the Reynolds averaged Navier-Stokes equations to account for turbulent effects and also a passive particle transport model. An analysis of particle deposition conditions is presented in this paper in terms of flow velocities and turbulence patterns. Then sediment deposition zones are presented thanks to the modeling with particle tracking method. It is shown that two recirculation zones seem to significantly influence sediment deposition. Due to the possible overestimation of particle trap efficiency with standard wall functions and stick conditions, further investigations seem required for basal boundary conditions based on turbulent kinetic energy and shear stress. These observations are confirmed by experimental investigations processed in the laboratory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=storm%20sewers" title="storm sewers">storm sewers</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20deposition" title=" sediment deposition"> sediment deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20investigation" title=" experimental investigation"> experimental investigation</a> </p> <a href="https://publications.waset.org/abstracts/69352/3d-modeling-of-flow-and-sediment-transport-in-tanks-with-the-influence-of-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2384</span> Automation Test Method and HILS Environment Configuration for Hydrogen Storage System Management Unit Verification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaejeogn%20Kim">Jaejeogn Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeongmin%20Hong"> Jeongmin Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jungin%20Lee"> Jungin Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Hydrogen Storage System Management Unit (HMU) is a controller that manages hydrogen charging and storage.

To perform verification under various conditions, it is necessary to increase time efficiency based on an automated verification environment and increase the reliability of the controller by applying numerous test cases.

Fung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Canada, more than 32% of the total energy demand is related to the building sector. Therefore, there is a great opportunity for Greenhouse Gases (GHG) reduction by integrating solar collectors to provide building heating load and domestic hot water (DHW). Despite the cold winter weather, Canada has a good number of sunny and clear days that can be considered for diurnal solar thermal energy storage. Due to the energy mismatch between building heating load and solar irradiation availability, relatively big storage tanks are usually needed to store solar thermal energy during the daytime and then use it at night. On the other hand, water tanks occupy huge space, especially in big cities, space is relatively expensive. This project investigates the possibility of using a specific building construction material (ICF – Insulated Concrete Form) as diurnal solar thermal energy storage that is integrated with a heat pump and microchannel solar thermal collector (MCST). Not much literature has studied the application of building pre-existing walls as active solar thermal energy storage as a feasible and industrialized solution for the solar thermal mismatch. By using ICF walls that are integrated into the building envelope, instead of big storage tanks, excess solar energy can be stored in the concrete of the ICF wall that consists of EPS insulation layers on both sides to store the thermal energy. In this study, two solar-based systems are designed and simulated inTransient Systems Simulation Program(TRNSYS)to compare ICF wall thermal storage benefits over the system without ICF walls. In this study, the heating load and DHW of a Canadian single-family house located in London, Ontario, are provided by solar-based systems. The proposed system integrates the MCST collector, a water-to-water HP, a preheat tank, the main tank, fan coils (to deliver the building heating load), and ICF walls. During the day, excess solar energy is stored in the ICF walls (charging cycle). Thermal energy can be restored from the ICF walls when the preheat tank temperature drops below the ICF wall (discharging process) to increase the COP of the heat pump. The evaporator of the heat pump is taking is coupled with the preheat tank. The provided warm water by the heat pump is stored in the second tank. Fan coil units are in contact with the tank to provide a building heating load. DHW is also delivered is provided from the main tank. It is investigated that the system with ICF walls with an average solar fraction of 82%- 88% can cover the whole heating demand+DHW of nine months and has a 10-15% higher average solar fraction than the system without ICF walls. Sensitivity analysis for different parameters influencing the solar fraction is discussed in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=net-zero%20building" title="net-zero building">net-zero building</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20thermal%20storage" title=" solar thermal storage"> solar thermal storage</a>, <a href="https://publications.waset.org/abstracts/search?q=microchannel%20solar%20thermal%20collector" title=" microchannel solar thermal collector"> microchannel solar thermal collector</a> </p> <a href="https://publications.waset.org/abstracts/156072/integration-of-icf-walls-as-diurnal-solar-thermal-storage-with-microchannel-solar-assisted-heat-pump-for-space-heating-and-domestic-hot-water-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156072.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2382</span> Managed Aquifer Recharge (MAR) for the Management of Stormwater on the Cape Flats, Cape Town</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Mauck">Benjamin Mauck</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Winter"> Kevin Winter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The city of Cape Town in South Africa, has shown consistent economic and population growth in the last few decades and that growth is expected to continue to increase into the future. These projected economic and population growth rates are set to place additional pressure on the city’s already strained water supply system. Thus, given Cape Town’s water scarcity, increasing water demands and stressed water supply system, coupled with global awareness around the issues of sustainable development, environmental protection and climate change, alternative water management strategies are required to ensure water is sustainably managed. Water Sensitive Urban Design (WSUD) is an approach to sustainable urban water management that attempts to assign a resource value to all forms of water in the urban context, viz. stormwater, wastewater, potable water and groundwater. WSUD employs a wide range of strategies to improve the sustainable management of urban water such as the water reuse, developing alternative available supply sources, sustainable stormwater management and enhancing the aesthetic and recreational value of urban water. Managed Aquifer Recharge (MAR) is one WSUD strategy which has proven to be a successful reuse strategy in a number of places around the world. MAR is the process where an aquifer is intentionally or artificially recharged, which provides a valuable means of water storage while enhancing the aquifers supply potential. This paper investigates the feasibility of implementing MAR in the sandy, unconfined Cape Flats Aquifer (CFA) in Cape Town. The main objective of the study is to assess if MAR is a viable strategy for stormwater management on the Cape Flats, aiding the prevention or mitigation of the seasonal flooding that occurs on the Cape Flats, while also improving the supply potential of the aquifer. This involves the infiltration of stormwater into the CFA during the wet winter months and in turn, abstracting from the CFA during the dry summer months for fit-for-purpose uses in order to optimise the recharge and storage capacity of the CFA. The fully-integrated MIKE SHE model is used in this study to simulate both surface water and groundwater hydrology. This modelling approach enables the testing of various potential recharge and abstraction scenarios required for implementation of MAR on the Cape Flats. Further MIKE SHE scenario analysis under projected future climate scenarios provides insight into the performance of MAR as a stormwater management strategy under climate change conditions. The scenario analysis using an integrated model such as MIKE SHE is a valuable tool for evaluating the feasibility of the MAR as a stormwater management strategy and its potential to contribute towards improving Cape Town’s water security into the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=managed%20aquifer%20recharge" title="managed aquifer recharge">managed aquifer recharge</a>, <a href="https://publications.waset.org/abstracts/search?q=stormwater%20management" title=" stormwater management"> stormwater management</a>, <a href="https://publications.waset.org/abstracts/search?q=cape%20flats%20aquifer" title=" cape flats aquifer"> cape flats aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=MIKE%20SHE" title=" MIKE SHE"> MIKE SHE</a> </p> <a href="https://publications.waset.org/abstracts/47344/managed-aquifer-recharge-mar-for-the-management-of-stormwater-on-the-cape-flats-cape-town" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47344.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2381</span> Use of Vapor Corrosion Inhibitor for Tank Bottom Protection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Arsalan%20Khan%20Sherwani">Muhammad Arsalan Khan Sherwani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of Volatile Corrosion Inhibitors (VCI) to protect Aboveground Storage Tank (AST) bottom plates against soil-side corrosion is one of the emerging corrosion prevention methods, specifically for tanks constructed on oily sand pad. Oily sand pad and the presence of air gaps underneath the bottom plates lead to severe corrosion and high metal thickness loss. In such cases, the cathodic protection cannot be fully considered as effective due to Cathodic Protection (CP) current shielding. These situations sometimes result in serious failures on multiple fronts, such as; containment losses, system shutdowns, extensive repairs, environmental impact and safety concerns in case of flammable fluids. Recently, East West Pipeline Department (EWPD) of Saudi Aramco has deployed this technology to one of the crude oil storage tanks, which showed high metal thickness loss during its out of service inspection. Soil-side corrosion rustled in major repairs of bottom plates and ultimately caused enormous unplanned activities in term of time as well as cost. This paper mainly focuses on the methodology of VCI installation, corrosion monitoring system and the expected results of protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vapor%20Corrosion%20Inhibitor" title="Vapor Corrosion Inhibitor">Vapor Corrosion Inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=Soil%20Side%20Corrosion" title=" Soil Side Corrosion"> Soil Side Corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=External%20Corrosion" title=" External Corrosion"> External Corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=Above%20Grade%20Storage%20Tank" title=" Above Grade Storage Tank"> Above Grade Storage Tank</a> </p> <a href="https://publications.waset.org/abstracts/167617/use-of-vapor-corrosion-inhibitor-for-tank-bottom-protection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167617.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2380</span> Terminal Ballistic Analysis of Non-Filled and Water-Filled Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Aziz">M.

The algorithm also calculates the volume of the detected damage from the depth map generated, for example, from the distance measurement unit. The proposed method was tested on data obtained by a tank barrel scanning device, which generates both surface image data and depth map. The article also discusses tank barrel scanning devices and how damaged surface impacts material resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barrel" title="barrel">barrel</a>, <a href="https://publications.waset.org/abstracts/search?q=barrel%20diagnostic" title=" barrel diagnostic"> barrel diagnostic</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20damage%20detection" title=" surface damage detection"> surface damage detection</a>, <a href="https://publications.waset.org/abstracts/search?q=tank" title=" tank"> tank</a> </p> <a href="https://publications.waset.org/abstracts/148441/tank-barrel-surface-damage-detection-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148441.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2377</span> Data-Driven Surrogate Models for Damage Prediction of Steel Liquid Storage Tanks under Seismic Hazard</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Micheli">Laura Micheli</a>, <a href="https://publications.waset.org/abstracts/search?q=Majd%20Hijazi"> Majd Hijazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Faytarouni"> Mahmoud Faytarouni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The damage reported by oil and gas industrial facilities revealed the utmost vulnerability of steel liquid storage tanks to seismic events. The failure of steel storage tanks may yield devastating and long-lasting consequences on built and natural environments, including the release of hazardous substances, uncontrolled fires, and soil contamination with hazardous materials. It is, therefore, fundamental to reliably predict the damage that steel liquid storage tanks will likely experience under future seismic hazard events. The seismic performance of steel liquid storage tanks is usually assessed using vulnerability curves obtained from the numerical simulation of a tank under different hazard scenarios. However, the computational demand of high-fidelity numerical simulation models, such as finite element models, makes the vulnerability assessment of liquid storage tanks time-consuming and often impractical. As a solution, this paper presents a surrogate model-based strategy for predicting seismic-induced damage in steel liquid storage tanks. In the proposed strategy, the surrogate model is leveraged to reduce the computational demand of time-consuming numerical simulations. To create the data set for training the surrogate model, field damage data from past earthquakes reconnaissance surveys and reports are collected. Features representative of steel liquid storage tank characteristics (e.g., diameter, height, liquid level, yielding stress) and seismic excitation parameters (e.g., peak ground acceleration, magnitude) are extracted from the field damage data. The collected data are then utilized to train a surrogate model that maps the relationship between tank characteristics, seismic hazard parameters, and seismic-induced damage via a data-driven surrogate model. Different types of surrogate algorithms, including naïve Bayes, k-nearest neighbors, decision tree, and random forest, are investigated, and results in terms of accuracy are reported. The model that yields the most accurate predictions is employed to predict future damage as a function of tank characteristics and seismic hazard intensity level. Results show that the proposed approach can be used to estimate the extent of damage in steel liquid storage tanks, where the use of data-driven surrogates represents a viable alternative to computationally expensive numerical simulation models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage%20prediction" title="damage prediction ">damage prediction </a>, <a href="https://publications.waset.org/abstracts/search?q=data-driven%20model" title=" data-driven model"> data-driven model</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20liquid%20storage%20tanks" title=" steel liquid storage tanks"> steel liquid storage tanks</a>, <a href="https://publications.waset.org/abstracts/search?q=surrogate%20model" title=" surrogate model"> surrogate model</a> </p> <a href="https://publications.waset.org/abstracts/130172/data-driven-surrogate-models-for-damage-prediction-of-steel-liquid-storage-tanks-under-seismic-hazard" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130172.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2376</span> Application of Global Predictive Real Time Control Strategy to Improve Flooding Prevention Performance of Urban Stormwater Basins</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shadab%20Shishegar">Shadab Shishegar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sophie%20Duchesne"> Sophie Duchesne</a>, <a href="https://publications.waset.org/abstracts/search?q=Genevieve%20%20Pelletier"> Genevieve Pelletier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainability as one of the key elements of Smart cities, can be realized by employing Real Time Control Strategies for city’s infrastructures. Nowadays Stormwater management systems play an important role in mitigating the impacts of urbanization on natural hydrological cycle. These systems can be managed in such a way that they meet the smart cities standards. In fact, there is a huge potential for sustainable management of urban stormwater and also its adaptability to global challenges like climate change. Hence, a dynamically managed system that can adapt itself to instability of the environmental conditions is desirable. A Global Predictive Real Time Control approach is proposed in this paper to optimize the performance of stormwater management basins in terms of flooding prevention. To do so, a mathematical optimization model is developed then solved using Genetic Algorithm (GA). Results show an improved performance at system-level for the stormwater basins in comparison to static strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20sustainability" title="environmental sustainability">environmental sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20control" title=" real time control"> real time control</a>, <a href="https://publications.waset.org/abstracts/search?q=storm%20water%20management" title=" storm water management"> storm water management</a> </p> <a href="https://publications.waset.org/abstracts/91205/application-of-global-predictive-real-time-control-strategy-to-improve-flooding-prevention-performance-of-urban-stormwater-basins" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91205.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2375</span> Comparative Study of Dynamic Effect on Analysis Approaches for Circular Tanks Using Codal Provisions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Deepak%20Kumar">P.

Analysis of liquid containing tanks is known to be complex due to hydrodynamic force exerted on tank which makes the analysis a complex one. The objective of this research is to carry out analysis of liquid domain along with structural interaction for various geometries of circular tanks considering seismic effects. An attempt has been made to determine hydrodynamic pressure distribution on the tank wall considering impulsive and convective components of liquid mass. To get a better picture, a comparative study of Draft IS 1893 Part 2, ACI 350.3 and Eurocode 8 for Circular Shaped Tank has been performed. Further, the differences in the magnitude of shear and moment at base as obtained from static (IS 3370 IV) and dynamic (Draft IS 1892 Part 2) analysis of ground supported circular tank highlight the need for us to mature from the old code to a newer code, which is more accurate and reliable. <p class="card-text"><strong>Keywords:</strong> <a
