Therefore, this study focused on sign structure among various vulnerable facilities. The evaluation of the wind fragility was carried out considering the destruction of the anchor, which is one of the various failure modes of the sign structure. The performance evaluation of the anchor was carried out to derive the wind fragility. Two parameters were set and four anchor types were selected to perform the pull-out and shear tests. The resistance capacity was estimated based on the experimental results. Wind loads were estimated using Monte Carlo simulation method. Based on these results, we derived the wind fragility according to anchor type and wind exposure category. Finally, the evaluation of the wind fragility was performed according to the experimental parameters such as anchor length and anchor diameter. This study shows that the depth of anchor was more significant for the safety of structure compare to diameter of anchor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sign%20structure" title="sign structure">sign structure</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20fragility" title=" wind fragility"> wind fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=set%20anchor" title=" set anchor"> set anchor</a>, <a href="https://publications.waset.org/abstracts/search?q=pull-out%20test" title=" pull-out test"> pull-out test</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20test" title=" shear test"> shear test</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation" title=" Monte Carlo simulation"> Monte Carlo simulation</a> </p> <a href="https://publications.waset.org/abstracts/85579/evaluation-of-wind-fragility-for-set-anchor-used-in-sign-structure-in-korea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85579.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">287</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">1296</span> Wind Fragility for Soundproof Wall with the Variation of Section Shape of Frame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seong%20Do%20Kim">Seong Do Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Woo%20Young%20Jung"> Woo Young Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, damages due to typhoons and strong wind are on the rise.

Monte Carlo Simulation method had been used to derive damage data and analytical fragilities were constructed. Fragility of window system showed that window located in leeward wall had higher probability of failure, especially those close to the edge of structure.

However, the combined effect of wind and temperature is the most critical limit state for chimney design. Hence, in the present paper, an efficient fragility analysis for concrete chimney is explored under combined wind and temperature effect. Wind time histories are generated by Davenports Power Spectral Density Function and using Weighed Amplitude Wave Superposition Technique. Fragility analysis is often carried out in full Monte Carlo Simulation framework, which requires extensive computational time. Thus, in the present paper, an efficient adaptive metamodelling technique is adopted to judiciously approximate limit state function, which will be subsequently used in the simulation framework. This will save substantial computational time and make the approach computationally efficient. Uncertainty in wind speed, wind load related parameters, and resistance-related parameters is considered. The results by the full simulation approach, conventional metamodelling approach and proposed adaptive metamodelling approach will be compared.

As typhoon disasters in Korea are constantly on the rise, probability risk assessment (PRA) has become a vital tool to evaluate the performance of civil structures. In this study, we attempted to determine the fragility of roof cladding with the screw connection. Experimental study was performed to evaluate the pull-out resistance of screw joints between honeycomb panels and back frames. Subsequently, by means of Monte Carlo Simulation method, probability of failure for these types of roof cladding was determined. The results that the failure of roof cladding was depends on their location on the roof, for example, the edge most panel has the highest probability of failure. <p class="card-text"><strong>Keywords:</strong> <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=roof%20cladding" title=" roof cladding"> roof cladding</a>, <a href="https://publications.waset.org/abstracts/search?q=screw%20pull-out%20strength" title=" screw pull-out strength"> screw pull-out strength</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20fragility" title=" wind fragility"> wind fragility</a> </p> <a href="https://publications.waset.org/abstracts/80016/wind-fragility-for-honeycomb-roof-cladding-panels-using-screw-pull-out-capacity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80016.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">253</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">1291</span> Feasibility of an Extreme Wind Risk Assessment Software for Industrial Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Pandolfi">Francesco Pandolfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgios%20Baltzopoulos"> Georgios Baltzopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Iunio%20Iervolino"> Iunio Iervolino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact of extreme winds on industrial assets and the built environment is gaining increasing attention from stakeholders, including the corporate insurance industry. This has led to a progressively more in-depth study of building vulnerability and fragility to wind. Wind vulnerability models are used in probabilistic risk assessment to relate a loss metric to an intensity measure of the natural event, usually a gust or a mean wind speed. In fact, vulnerability models can be integrated with the wind hazard, which consists of associating a probability to each intensity level in a time interval (e.g., by means of return periods) to provide an assessment of future losses due to extreme wind. This has also given impulse to the world- and regional-scale wind hazard studies.Another approach often adopted for the probabilistic description of building vulnerability to the wind is the use of fragility functions, which provide the conditional probability that selected building components will exceed certain damage states, given wind intensity. In fact, in wind engineering literature, it is more common to find structural system- or component-level fragility functions rather than wind vulnerability models for an entire building. Loss assessment based on component fragilities requires some logical combination rules that define the building鈥檚 damage state given the damage state of each component and the availability of a consequence model that provides the losses associated with each damage state. When risk calculations are based on numerical simulation of a structure鈥檚 behavior during extreme wind scenarios, the interaction of component fragilities is intertwined with the computational procedure. However, simulation-based approaches are usually computationally demanding and case-specific. In this context, the present work introduces the ExtReMe wind risk assESsment prototype Software, ERMESS, which is being developed at the University of Naples Federico II. ERMESS is a wind risk assessment tool for insurance applications to industrial facilities, collecting a wide assortment of available wind vulnerability models and fragility functions to facilitate their incorporation into risk calculations based on in-built or user-defined wind hazard data. This software implements an alternative method for building-specific risk assessment based on existing component-level fragility functions and on a number of simplifying assumptions for their interactions. The applicability of this alternative procedure is explored by means of an illustrative proof-of-concept example, which considers four main building components, namely: the roof covering, roof structure, envelope wall and envelope openings. The application shows that, despite the simplifying assumptions, the procedure can yield risk evaluations that are comparable to those obtained via more rigorous building-level simulation-based methods, at least in the considered example. The advantage of this approach is shown to lie in the fact that a database of building component fragility curves can be put to use for the development of new wind vulnerability models to cover building typologies not yet adequately covered by existing works and whose rigorous development is usually beyond the budget of portfolio-related industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=component%20wind%20fragility" title="component wind fragility">component wind fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20risk%20assessment" title=" probabilistic risk assessment"> probabilistic risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability%20model" title=" vulnerability model"> vulnerability model</a>, <a href="https://publications.waset.org/abstracts/search?q=wind-induced%20losses" title=" wind-induced losses"> wind-induced losses</a> </p> <a href="https://publications.waset.org/abstracts/133506/feasibility-of-an-extreme-wind-risk-assessment-software-for-industrial-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133506.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">181</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">1290</span> Seismic Fragility Curves Methodologies for Bridges: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amirmozafar%20Benshams">Amirmozafar Benshams</a>, <a href="https://publications.waset.org/abstracts/search?q=Khatere%20Kashmari"> Khatere Kashmari</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Hatami"> Farzad Hatami</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesbah%20Saybani"> Mesbah Saybani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a part of the transportation network, bridges are one of the most vulnerable structures.

Results show that the probability of failure in moderate damage for deteriorated model was found to be larger than pre-deterioration model when peak ground acceleration (PGA) passed 0.4 g. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=weir" title="weir">weir</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=fragility" title=" fragility"> fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a> </p> <a href="https://publications.waset.org/abstracts/68378/seismic-fragility-for-sliding-failure-of-weir-structure-considering-the-process-of-concrete-aging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68378.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">424</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">1288</span> A Review of Current Knowledge on Assessment of Precast Structures Using Fragility Curves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Akpinar">E.

Such structures are rather popular for industrial buildings. For the sake of economic importance of such industrial buildings as well as significance of safety, like every other type of structures, performance assessment and structural risk analysis are important. Fragility curves are powerful tools for damage projection and assessment for any sort of building as well as precast structures. In this study, a comparative review of current knowledge on fragility analysis of industrial precast RC structures were presented and findings in previous studies were compiled. Effects of different structural variables, parameters and building geometries as well as soil conditions on fragility analysis of precast structures are reviewed. It was aimed to briefly present the information in the literature about the procedure of damage probability prediction including fragility curves for such industrial facilities. It is found that determination of the aforementioned structural parameters as well as selecting analysis procedure are critically important for damage prediction of industrial precast RC structures using fragility curves. <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=fragility%20curve" title=" fragility curve"> fragility curve</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20buildings" title=" industrial buildings"> industrial buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=precast%20reinforced%20concrete%20structures" title=" precast reinforced concrete structures"> precast reinforced concrete structures</a> </p> <a href="https://publications.waset.org/abstracts/100004/a-review-of-current-knowledge-on-assessment-of-precast-structures-using-fragility-curves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100004.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">189</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">1287</span> Potentiality of the Wind Energy in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Benoudjafer">C.

This paper proposes the procedure to estimate seismic fragility curves using an incremental dynamic analysis (IDA) rather than the method adopting a CSM. To achieve the research purpose, this study compares the seismic fragility curves of a 5-story reinforced concrete (RC) moment frame obtained from both methods, an IDA method and a CSM. Both seismic fragility curves are similar in slight and moderate damage states whereas the fragility curve obtained from the IDA method presents less variation (or uncertainties) in extensive and complete damage states. This is due to the fact that the IDA method can properly capture the structural response beyond yielding rather than the CSM and can directly calculate higher mode effects. From these observations, the CSM could overestimate seismic vulnerabilities of the studied structure in extensive or complete damage states. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20fragility%20curve" title="seismic fragility curve">seismic fragility curve</a>, <a href="https://publications.waset.org/abstracts/search?q=incremental%20dynamic%20analysis" title=" incremental dynamic analysis"> incremental dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=capacity%20spectrum%20method" title=" capacity spectrum method"> capacity spectrum method</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20moment%20frame" title=" reinforced concrete moment frame"> reinforced concrete moment frame</a> </p> <a href="https://publications.waset.org/abstracts/21652/seismic-fragility-functions-of-rc-moment-frames-using-incremental-dynamic-analyses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21652.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">422</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">1285</span> Fragility Assessment for Torsionally Asymmetric Buildings in Plan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Feli">S.

In order to understand the influence of concrete aging on the weir structure, by using probabilistic risk assessment, the analytical seismic fragility of the weir structure was derived for pre- and post-deterioration of concrete. The performance of concrete weir structure after five years was assumed for the concrete aging or deterioration, and according to after five years’ condition, the elastic modulus was simply reduced about one–tenth compared with initial condition of weir structures. A 2D nonlinear finite element analysis was performed considering the deterioration of concrete in weir structures using ABAQUS platform, a commercial structural analysis program. Simplified concrete degradation was resulted in the increase of almost 45% of the probability of failure at Limit State 3, in comparison to initial construction stage, by analyzing the seismic fragility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=weir" title="weir">weir</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=fragility" title=" fragility"> fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a> </p> <a href="https://publications.waset.org/abstracts/72469/seismic-fragility-of-weir-structure-considering-aging-degradation-of-concrete-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72469.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">483</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">1283</span> Selection of Intensity Measure in Probabilistic Seismic Risk Assessment of a Turkish Railway Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20F.%20Yilmaz">M.

Also, it is used to determine the nonlinear behavior of bridges. There are many historical bridges in the Turkish railway network; the earthquake performances of these bridges are needed to be investigated. To derive fragility curve Intensity measures (IMs) and Engineering demand parameters (EDP) are needed to be determined. And the relation between IMs and EDP are needed to be derived. In this study, a typical simply supported steel girder riveted railway bridge is studied. Fragility curves of this bridge are derived by two parameters lognormal distribution. Time history analyses are done for selected 60 real earthquake data to determine the relation between IMs and EDP. Moreover, efficiency, practicality, and sufficiency of three different IMs are discussed. PGA, Sa(0.2s) and Sa(1s), the most common used IMs parameters for fragility curve in the literature, are taken into consideration in terms of efficiency, practicality and sufficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=railway%20bridges" title="railway bridges">railway bridges</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake%20performance" title=" earthquake performance"> earthquake performance</a>, <a href="https://publications.waset.org/abstracts/search?q=fragility%20analyses" title=" fragility analyses"> fragility analyses</a>, <a href="https://publications.waset.org/abstracts/search?q=selection%20of%20intensity%20measures" title=" selection of intensity measures"> selection of intensity measures</a> </p> <a href="https://publications.waset.org/abstracts/65523/selection-of-intensity-measure-in-probabilistic-seismic-risk-assessment-of-a-turkish-railway-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65523.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">357</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">1282</span> Experimental Investigation of Tip-Speed-Ratio Effects on Wake Dynamics of Horizontal-Axis Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20Bayron">Paul Bayron</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Kelso"> Richard Kelso</a>, <a href="https://publications.waset.org/abstracts/search?q=Rey%20Chin"> Rey Chin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wind tunnel experiments were performed in the KC closed-circuit wind tunnel in the University of Adelaide to study the influence of tip-speed-ratio ( <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hotwire%20anemometry" title="hotwire anemometry">hotwire anemometry</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20dynamics" title=" wake dynamics"> wake dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title=" wind tunnel"> wind tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbines" title=" wind turbines"> wind turbines</a> </p> <a href="https://publications.waset.org/abstracts/137158/experimental-investigation-of-tip-speed-ratio-effects-on-wake-dynamics-of-horizontal-axis-wind-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137158.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">215</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">1281</span> A Study on Method for Identifying Capacity Factor Declination of Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dongheon%20Shin">Dongheon Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyungnam%20Ko"> Kyungnam Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Jongchul%20Huh"> Jongchul Huh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The investigation on wind turbine degradation was carried out using the nacelle wind data.

Since in the sea, the wind turbine structures are under water and structures interactions, the dynamic analysis has been conducted under combined wind and wave loading. The offshore wind turbines have been investigated undertow models of normal and severe wind turbulence, and the results of this study show that the amplitude of fluctuation of dynamic response of structures including thrust force and base shear force of structures is increased with increasing the amount of wind turbulence, and this increase is not necessarily observed in the mean values of responses.

Job losses and/or reduced wages and insecurity increased the number of people that were unable to meet unexpected expenses, which, in many cases, led to increased household debt levels. This presents a threat to the stability of the financial system and the whole economy; therefore, reducing financial fragility and improving financial literacy present challenges for academicians, practitioners, and policymakers. Concerning financial fragility, significant research attention has been devoted to financial knowledge and financial literacy. However, apart from specific knowledge, personal characteristics are of great importance in making financial decisions in the household. Self-efficacy is one of the personal non-cognitive attributes that is a valuable framework for understanding how household financial decisions are made. Thus, this research proposes that individual levels of financial literacy and self-efficacy are related to the indebtedness and financial instability of the household. The primary data were collected using a structured, self-administered online questionnaire, and a snowball sampling method was applied to reach the participants. Preliminary results confirm our assumptions on the influence of financial literacy and self-efficacy on household financial stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20literacy" title="financial literacy">financial literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=self-efficacy" title=" self-efficacy"> self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20financial%20fragility" title=" household financial fragility"> household financial fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=well-being" title=" well-being"> well-being</a> </p> <a href="https://publications.waset.org/abstracts/166473/the-role-of-financial-literacy-and-personal-non-cognitive-attributes-in-household-financial-fragility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166473.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">87</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">1277</span> Fragility Analysis of Weir Structure Subjected to Flooding Water Damage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oh%20Hyeon%20Jeon">Oh Hyeon Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=WooYoung%20Jung"> WooYoung Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, seepage analysis was performed by the level difference between upstream and downstream of weir structure for safety evaluation of weir structure against flooding. Monte Carlo Simulation method was employed by considering the probability distribution of the adjacent ground parameter, i.e., permeability coefficient of weir structure. Moreover, by using a commercially available finite element program (ABAQUS), modeling of the weir structure is carried out. Based on this model, the characteristic of water seepage during flooding was determined at each water level with consideration of the uncertainty of their corresponding permeability coefficient. Subsequently, fragility function could be constructed based on this response from numerical analysis; this fragility function results could be used to determine the weakness of weir structure subjected to flooding disaster. They can also be used as a reference data that can comprehensively predict the probability of failur,e and the degree of damage of a weir structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=weir%20structure" title="weir structure">weir structure</a>, <a href="https://publications.waset.org/abstracts/search?q=seepage" title=" seepage"> seepage</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20disaster%20fragility" title=" flood disaster fragility"> flood disaster fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20risk%20assessment" title=" probabilistic risk assessment"> probabilistic risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte-Carlo%20simulation" title=" Monte-Carlo simulation"> Monte-Carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=permeability%20coefficient" title=" permeability coefficient"> permeability coefficient</a> </p> <a href="https://publications.waset.org/abstracts/88549/fragility-analysis-of-weir-structure-subjected-to-flooding-water-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88549.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">352</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">1276</span> Wind Energy Potential of Southern Sindh, Pakistan for Power Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Akhlaque%20Ahmed">M.

The monthly average wind speed for these area ranges from 4.5m/sec to 8.5m/sec at 30m height from ground. Extractable wind power, wind energy and Weibul parameter for above mentioned areas have been examined. Furthermore, the power output using fast and slow wind machine using different blade diameter along with the 4Kw and 20 Kw aero-generator were examined to see the possible use for deep well pumping and electricity supply to remote villages. The analysis reveals that in this wind corridor of southern Sindh Hawksbay, Ketibander and Shahbander belongs to wind power class-3 Hyderabad and Nooriabad belongs to wind power class-5 and Karachi belongs to wind power class-2. The result shows that the that higher wind speed values occur between June till August. It was found that considering maximum wind speed location, Hawksbay,Noriabad are the best location for setting up wind machines for power generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20energy%20generation" title="wind energy generation">wind energy generation</a>, <a href="https://publications.waset.org/abstracts/search?q=Southern%20Sindh" title=" Southern Sindh"> Southern Sindh</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20change" title=" seasonal change"> seasonal change</a>, <a href="https://publications.waset.org/abstracts/search?q=Weibull%20parameter" title=" Weibull parameter"> Weibull parameter</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20machines" title=" wind machines"> wind machines</a> </p> <a href="https://publications.waset.org/abstracts/100211/wind-energy-potential-of-southern-sindh-pakistan-for-power-generation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100211.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">149</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">1275</span> Seismic Fragility Curves for Shallow Circular Tunnels under Different Soil Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Khadijah%20Che%20Osmi">Siti Khadijah Che Osmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Mohd%20Ahmad"> Syed Mohd Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a methodology to develop fragility curves for shallow tunnels so as to describe a relationship between seismic hazard and tunnel vulnerability. Emphasis is given to the influence of surrounding soil material properties because the dynamic behaviour of the tunnel mostly depends on it. Four ground properties of soils ranging from stiff to soft soils are selected. A 3D nonlinear time history analysis is used to evaluate the seismic response of the tunnel when subjected to five real earthquake ground intensities. The derived curves show the future probabilistic performance of the tunnels based on the predicted level of damage states corresponding to the peak ground acceleration. A comparison of the obtained results with the previous literature is provided to validate the reliability of the proposed fragility curves. Results show the significant role of soil properties and input motions in evaluating the seismic performance and response of shallow tunnels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fragility%20analysis" title="fragility analysis">fragility analysis</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=tunnel%20lining" title=" tunnel lining"> tunnel lining</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title=" vulnerability"> vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/57352/seismic-fragility-curves-for-shallow-circular-tunnels-under-different-soil-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57352.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">314</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">1274</span> Seismic Fragility of Base-Isolated Multi-Story Piping System in Critical Facilities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bu%20Seog%20Ju">Bu Seog Ju</a>, <a href="https://publications.waset.org/abstracts/search?q=Ho%20Young%20Son"> Ho Young Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Hee%20Ryu"> Yong Hee Ryu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is focused on the evaluation of seismic fragility of multi-story piping system installed in critical structures, isolated with triple friction pendulum bearing. The concept of this study is to isolate the critical building structure as well as nonstructural component, especially piping system in order to mitigate the earthquake damage and achieve the reliable seismic design. Then, the building system and multi-story piping system was modeled in OpenSees. In particular, the triple friction pendulum isolator was accounted for the vertical and horizontal coupling behavior in the building system subjected to seismic ground motions. Consequently, in order to generate the seismic fragility of base-isolated multi-story piping system, 21 selected seismic ground motions were carried out, by using Monte Carlo Simulation accounted for the uncertainties in demand. Finally, the system-level fragility curves corresponding to the limit state of the piping system was conducted at each T-joint system, which was commonly failure points in piping systems during and after an earthquake. Additionally, the system-level fragilities were performed to the first floor and second floor level in critical structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fragility" title="fragility">fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20pendulum%20bearing" title=" friction pendulum bearing"> friction pendulum bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=nonstructural%20component" title=" nonstructural component"> nonstructural component</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a> </p> <a href="https://publications.waset.org/abstracts/96709/seismic-fragility-of-base-isolated-multi-story-piping-system-in-critical-facilities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96709.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">150</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">1273</span> Seismic Fragility Assessment of Continuous Integral Bridge Frames with Variable Expansion Joint Clearances</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Mounnarath">P.

Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fragility analysis is an effective tool for the seismic vulnerability assessment of civil structures in the last several years. The design of the expansion joints according to various bridge design codes is almost inconsistent, and only a few studies have focused on this problem so far. In this study, the influence of the expansion joint clearances between the girder ends and the abutment backwalls on the seismic fragility assessment of continuous integral bridge frames is investigated. The gaps (ranging from 60 mm, 150 mm, 250 mm and 350 mm) are designed by following two different bridge design code specifications, namely, Caltrans and Eurocode 8-2. Five bridge models are analyzed and compared. The first bridge model serves as a reference. This model uses three-dimensional reinforced concrete fiber beam-column elements with simplified supports at both ends of the girder. The other four models also employ reinforced concrete fiber beam-column elements but include the abutment backfill stiffness and four different gap values. The nonlinear time history analysis is performed. The artificial ground motion sets, which have the peak ground accelerations (PGAs) ranging from 0.1 g to 1.0 g with an increment of 0.05 g, are taken as input. The soil-structure interaction and the P-Δ effects are also included in the analysis. The component fragility curves in terms of the curvature ductility demand to the capacity ratio of the piers and the displacement demand to the capacity ratio of the abutment sliding bearings are established and compared. The system fragility curves are then obtained by combining the component fragility curves. Our results show that in the component fragility analysis, the reference bridge model exhibits a severe vulnerability compared to that of other sophisticated bridge models for all damage states. In the system fragility analysis, the reference curves illustrate a smaller damage probability in the earlier PGA ranges for the first three damage states, they then show a higher fragility compared to other curves in the larger PGA levels. In the fourth damage state, the reference curve has the smallest vulnerability. In both the component and the system fragility analysis, the same trend is found that the bridge models with smaller clearances exhibit a smaller fragility compared to that with larger openings. However, the bridge model with a maximum clearance still induces a minimum pounding force effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=expansion%20joint%20clearance" title="expansion joint clearance">expansion joint clearance</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20beam-column%20element" title=" fiber beam-column element"> fiber beam-column element</a>, <a href="https://publications.waset.org/abstracts/search?q=fragility%20assessment" title=" fragility assessment"> fragility assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20history%20analysis" title=" time history analysis"> time history analysis</a> </p> <a href="https://publications.waset.org/abstracts/35784/seismic-fragility-assessment-of-continuous-integral-bridge-frames-with-variable-expansion-joint-clearances" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35784.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">435</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">1272</span> An Assessment of Wind Energy in Sanar Village in North of Iran Using Weibull Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsanolah%20Assareh">Ehsanolah Assareh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Biglari"> Mojtaba Biglari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Nedaei"> Mojtaba Nedaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sanar village in north of Iran is a remote region with difficult access to electricity, grid and water supply. Thus the aim of this research is to evaluate the potential of wind as a power source either for electricity generation or for water pumping. In this study the statistical analysis has been performed by Weibull distribution function. The results show that the Weibull distribution has fitted the wind data very well. Also it has been demonstrated that wind speed at 40 m height is ranged from 1.75 m/s in Dec to 3.28 m/s in Aug with average value of 2.69 m/s. In this research, different wind speed characteristics such as turbulence intensity, wind direction, monthly air temperature, humidity wind power density and other related parameters have been investigated. Finally it was concluded that the wind energy in the Sanar village may be explored by employing modern wind turbines that require very lower start-up speeds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20energy" title="wind energy">wind energy</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title=" wind turbine"> wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=weibull" title=" weibull"> weibull</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanar%20village" title=" Sanar village"> Sanar village</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/16648/an-assessment-of-wind-energy-in-sanar-village-in-north-of-iran-using-weibull-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16648.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">523</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">1271</span> Experimental and CFD of Desgined Small Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tarek%20A.%20Mekail">Tarek A.

In addition to the direct salaries associated with building and operating wind projects, the wind energy industry provides indirect jobs and benefits. The optimal planning of a wind farm is one most important topic in renewable energy technology. Many methods have been implemented to optimize the cost and output benefit of wind farms, but the contribution of this paper is mentioning different types of service providers and also time of installation of wind turbines during planning horizon years.

To reduce cost of wind energy is a challenge. Before building of wind park conditions such as: average wind speed, direction, time for each wind, probability of icing, must be considered in the design phase. Operation values used on the setting of control systems also will depend on mentioned variables. Here it is proposed a procedure to be include in the evaluation of the performance of a wind turbine, based on the amplitude of wind changes, the number of changes and their duration. A generic study case based on actual data is presented. Data analysing techniques were applied to model the power required for yaw system based on amplitude and data amount of wind changes. A theoretical model between time, amplitude of wind changes and angular speed of nacelle rotation was identified. <p class="card-text"><strong>Keywords:</strong> <a
