The selected parameters have been thought to be effective on the performance of RC buildings. In the performance analyses stage of the study, level of performance possible to be shown by these buildings in case of an earthquake was determined on the basis of the 4-grade performance levels specified in Turkish Earthquake Code- 2007 (TEC-2007). After obtaining the 4-grade performance level, selected 23 parameters of each building have been matched with the performance level. In this stage, ANN-based fast evaluation algorithm mentioned above made an economic and rapid evaluation of four to ten storey RC buildings.

Cognitive engineering structure characteristics through seismic damage phenomenon are often far superior to expensive shaking table experiments. After the earthquake, people will record a variety of different types of engineering damage photos. However, a large number of earthquake damage photographs lack sufficient information and reduce their using value. To improve the research value and the use efficiency of engineering seismic damage photographs, this paper objects to explore and show seismic damage background information, which includes the earthquake magnitude, earthquake intensity, and the damaged structure characteristics. From the research requirement in earthquake engineering field, the authors use the 2008 China Wenchuan M8.0 earthquake photographs, and provide four kinds of attribute indexes and classification, which are seismic information, structure types, earthquake damage parts and disaster causation factors. The final object is to set up an engineering structural seismic damage database based on these four attribute indicators and classification, and eventually build a website providing seismic damage photographs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attribute%20index" title="attribute index">attribute index</a>, <a href="https://publications.waset.org/abstracts/search?q=classification%20method" title=" classification method"> classification method</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake%20damage%20picture" title=" earthquake damage picture"> earthquake damage picture</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20structure" title=" engineering structure"> engineering structure</a> </p> <a href="https://publications.waset.org/abstracts/66126/attribute-index-and-classification-method-of-earthquake-damage-photographs-of-engineering-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66126.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">765</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">13364</span> Observed Damages to Adobe Masonry Buildings after 2011 Van Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eylem%20G%C3%BCzel">Eylem Güzel</a>, <a href="https://publications.waset.org/abstracts/search?q=Soner%20G%C3%BCler"> Soner Güler</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20G%C3%BClen"> Mustafa Gülen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Masonry is the oldest building materials since ancient times.

According to the damage states of RC columns and their corresponding seismic reduction factors suggested by experimental data, this work applies the detailed seismic performance assessment method to identify the seismic capacity of earthquake-damaged RC buildings. Additionally, a post-earthquake emergent assessment procedure is proposed that can provide the data needed for decision about earthquake-damaged buildings in a region with high seismic hazard.

Virtex-Field Programmable Gate Arrays (FPGAs) are programmable silicon foundations which offer an important solution for addressing the needs of high performance DSP designer. In this work, Virtex-7 FPGA technology is used to implement an iterative algorithm to estimate the earthquake location. Simulation results show that an implementation based on block RAMB36E1 and DSP48E1 slices of Virtex-7 type reduces the number of cycles of the clock frequency.

The key element of this ability is mathematical modeling of really loadings situation into a simple loads input to use in structure analysis and design. Amongst many different types of loads, the most challenging load is earthquake load. It is possible magnitude is unclear and timing is unknown. Therefore the concept of intended loads and safety have been built on experience of previous earthquake impact on the structures. Understanding and developing these concepts is achieved by investigating performance of the structures after real earthquakes. Damage after an earthquake provide results of thousands of full-scale structure test under a real seismic load. Thus, Earthquakes reveille all the weakness, mistakes and deficiencies of analysis, design rules and practice. This study deals with lesson learnt from earthquake recoded last two decades in Turkey. Results of investigation after several earthquakes exposes many deficiencies in structural detailing, inappropriate design, wrong architecture layout, and mainly mistake in construction practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake" title="earthquake">earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20assessment" title=" seismic assessment"> seismic assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20buildings" title=" RC buildings"> RC buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20performance" title=" building performance "> building performance </a> </p> <a href="https://publications.waset.org/abstracts/59861/earthquakes-and-buildings-lesson-learnt-from-past-earthquakes-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59861.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">264</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">13357</span> Performance of On-site Earthquake Early Warning Systems for Different Sensor Locations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ting-Yu%20Hsu">Ting-Yu Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyu-Yu%20Wu"> Shyu-Yu Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shieh-Kung%20Huang"> Shieh-Kung Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung-Wei%20Chiang"> Hung-Wei Chiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kung-Chun%20Lu"> Kung-Chun Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pei-Yang%20Lin"> Pei-Yang Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuo-Liang%20Wen"> Kuo-Liang Wen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Regional earthquake early warning (EEW) systems are not suitable for Taiwan, as most destructive seismic hazards arise due to in-land earthquakes. These likely cause the lead-time provided by regional EEW systems before a destructive earthquake wave arrives to become null. On the other hand, an on-site EEW system can provide more lead-time at a region closer to an epicenter, since only seismic information of the target site is required. Instead of leveraging the information of several stations, the on-site system extracts some P-wave features from the first few seconds of vertical ground acceleration of a single station and performs a prediction of the oncoming earthquake intensity at the same station according to these features. Since seismometers could be triggered by non-earthquake events such as a passing of a truck or other human activities, to reduce the likelihood of false alarms, a seismometer was installed at three different locations on the same site and the performance of the EEW system for these three sensor locations were discussed. The results show that the location on the ground of the first floor of a school building maybe a good choice, since the false alarms could be reduced and the cost for installation and maintenance is the lowest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake%20early%20warning" title="earthquake early warning">earthquake early warning</a>, <a href="https://publications.waset.org/abstracts/search?q=on-site" title=" on-site"> on-site</a>, <a href="https://publications.waset.org/abstracts/search?q=seismometer%20location" title=" seismometer location"> seismometer location</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a> </p> <a href="https://publications.waset.org/abstracts/48504/performance-of-on-site-earthquake-early-warning-systems-for-different-sensor-locations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48504.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">243</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">13356</span> A Brief Overview of Seven Churches in Van Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eylem%20G%C3%BCzel">Eylem Güzel</a>, <a href="https://publications.waset.org/abstracts/search?q=Soner%20Guler"> Soner Guler</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Gulen"> Mustafa Gulen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Van province which has a very rich historical heritage is located in eastern part of Turkey, between Lake Van and the Iranian border.

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">13354</span> Introduction of the Harmfulness of the Seismic Signal in the Assessment of the Performance of Reinforced Concrete Frame Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kahil%20Amar">Kahil Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Boukais%20Said"> Boukais Said</a>, <a href="https://publications.waset.org/abstracts/search?q=Kezmane%20Ali"> Kezmane Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannachi%20Naceur%20Eddine"> Hannachi Naceur Eddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamizi%20Mohand"> Hamizi Mohand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The principle of the seismic performance evaluation methods is to provide a measure of capability for a building or set of buildings to be damaged by an earthquake.

The investigation of the mappings shows that vertical earthquake acceleration can be significantly closer to the maximum horizontal earthquake acceleration, and even exceeds it in some cases. This study has compared the behavior of different members of three steel moment frame with a buckling-restrained brace (BRB), one time only by considering the horizontal component and again by considering simultaneously the horizontal and vertical components under the three mappings of the near-fault area and the effect of vertical acceleration on structural responses is investigated. Finally, according to the results, the vertical component of the earthquake has a greater effect on the axial force of the columns and the vertical displacement of the middle of the beams of the different classes and less on the lateral displacement of the classes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vertical%20earthquake%20acceleration" title="vertical earthquake acceleration">vertical earthquake acceleration</a>, <a href="https://publications.waset.org/abstracts/search?q=near-fault%20area" title=" near-fault area"> near-fault area</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20frame" title=" steel frame"> steel frame</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20and%20vertical%20component%20of%20earthquake" title=" horizontal and vertical component of earthquake"> horizontal and vertical component of earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling-restrained%20brace" title=" buckling-restrained brace"> buckling-restrained brace</a> </p> <a href="https://publications.waset.org/abstracts/91326/the-simultaneous-effect-of-horizontal-and-vertical-earthquake-components-on-the-seismic-response-of-buckling-restrained-braced-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91326.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">179</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">13350</span> Sustainable Design of Coastal Bridge Networks in the Presence of Multiple Flood and Earthquake Risks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riyadh%20Alsultani">Riyadh Alsultani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Majdi"> Ali Majdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is necessary to develop a design methodology that includes the possibility of seismic events occurring in a region, the vulnerability of the civil hydraulic structure, and the effects of the occurrence hazard on society, environment, and economy in order to evaluate the flood and earthquake risks of coastal bridge networks. This paper presents a design approach for the assessment of the risk and sustainability of coastal bridge networks under time-variant flood-earthquake conditions. The social, environmental, and economic indicators of the network are used to measure its sustainability. These consist of anticipated loss, downtime, energy waste, and carbon dioxide emissions. The design process takes into account the possibility of happening in a set of flood and earthquake scenarios that represent the local seismic activity. Based on the performance of each bridge as determined by fragility assessments, network linkages are measured. The network's connections and bridges' damage statuses after an earthquake scenario determine the network's sustainability and danger. The sustainability measures' temporal volatility and the danger of structural degradation are both highlighted.

Effective post-earthquake evacuation is critical for ensuring the safety of building occupants. However, current design practices often neglect the integration of post-earthquake evacuation considerations into the early-stage architectural design process. To address this gap, this paper presents a novel automated internal architectural layout generation tool that optimizes post-earthquake evacuation performance. The tool takes an initial plain floor plan as input, along with specific requirements from the user/architect, such as minimum room dimensions, corridor width, and exit lengths. Based on these inputs, firstly, the tool randomly generates different architectural layouts. Secondly, the human post-earthquake evacuation behaviour will be thoroughly assessed for each generated layout using the advanced Agent-Based Building Earthquake Evacuation Simulation (AB2E2S) model. The AB2E2S prototype is a post-earthquake evacuation simulation tool that incorporates variables related to earthquake intensity, architectural layout, and human factors. It leverages a hierarchical agent-based simulation approach, incorporating reinforcement learning to mimic human behaviour during evacuation. The model evaluates different layout options and provides feedback on evacuation flow, time, and possible casualties due to earthquake non-structural damage. By integrating the AB2E2S model into the automated layout generation tool, architects and designers can obtain optimized architectural layouts that prioritize post-earthquake evacuation performance. Through the use of the tool, architects and designers can explore various design alternatives, considering different minimum room requirements, corridor widths, and exit lengths. This approach ensures that evacuation considerations are embedded in the early stages of the design process. In conclusion, this research presents an innovative automated internal architectural layout generation tool that integrates post-earthquake evacuation simulation. By incorporating evacuation considerations into the early-stage design process, architects and designers can optimize building layouts for improved post-earthquake evacuation performance. This tool empowers professionals to create resilient designs that prioritize the safety of building occupants in the face of seismic events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agent-based%20simulation" title="agent-based simulation">agent-based simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=automation%20in%20design" title=" automation in design"> automation in design</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20layout" title=" architectural layout"> architectural layout</a>, <a href="https://publications.waset.org/abstracts/search?q=post-earthquake%20evacuation%20behavior" title=" post-earthquake evacuation behavior"> post-earthquake evacuation behavior</a> </p> <a href="https://publications.waset.org/abstracts/172028/automated-building-internal-layout-design-incorporating-post-earthquake-evacuation-considerations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172028.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">104</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">13348</span> Effects of Damper Locations and Base Isolators on Seismic Response of a Building Frame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azin%20Shakibabarough">Azin Shakibabarough</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Valinejadshoubi"> Mojtaba Valinejadshoubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20Bagchi"> Ashutosh Bagchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structural vibration means repetitive motion that causes fatigue and reduction of the performance of a structure. An earthquake may release high amount of energy that can have adverse effect on all components of a structure. Therefore, decreasing of vibration or maintaining performance of structures such as bridges, dams, roads and buildings is important for life safety and reducing economic loss. When earthquake or any vibration happens, investigation on parts of a structure which sustain the seismic loads is mandatory to provide a safe condition for the occupants. One of the solutions for reducing the earthquake vibration in a structure is using of vibration control devices such as dampers and base isolators. The objective of this study is to investigate the optimal positions of friction dampers and base isolators for better seismic response of 2D frame. For this purpose, a two bay and six story frame with different distribution formats was modeled and some of their responses to earthquake such as inter-story drift, max joint displacement, max axial force and max bending moment were determined and compared using non-linear dynamic analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20nonlinear%20analysis" title="fast nonlinear analysis">fast nonlinear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20damper" title=" friction damper"> friction damper</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20isolator" title=" base isolator"> base isolator</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20vibration%20control" title=" seismic vibration control"> seismic vibration control</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20response" title=" seismic response"> seismic response</a> </p> <a href="https://publications.waset.org/abstracts/50373/effects-of-damper-locations-and-base-isolators-on-seismic-response-of-a-building-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50373.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">321</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">13347</span> Seismic Performance of Slopes Subjected to Earthquake Mainshock Aftershock Sequences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alisha%20Khanal">Alisha Khanal</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Saygili"> Gokhan Saygili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is commonly observed that aftershocks follow the mainshock. Aftershocks continue over a period of time with a decreasing frequency and typically there is not sufficient time for repair and retrofit between a mainshock–aftershock sequence. Usually, aftershocks are smaller in magnitude; however, aftershock ground motion characteristics such as the intensity and duration can be greater than the mainshock due to the changes in the earthquake mechanism and location with respect to the site. The seismic performance of slopes is typically evaluated based on the sliding displacement predicted to occur along a critical sliding surface. Various empirical models are available that predict sliding displacement as a function of seismic loading parameters, ground motion parameters, and site parameters but these models do not include the aftershocks. The seismic risks associated with the post-mainshock slopes ('damaged slopes') subjected to aftershocks is significant. This paper extends the empirical sliding displacement models for flexible slopes subjected to earthquake mainshock-aftershock sequences (a multi hazard approach). A dataset was developed using 144 pairs of as-recorded mainshock-aftershock sequences using the Pacific Earthquake Engineering Research Center (PEER) database. The results reveal that the combination of mainshock and aftershock increases the seismic demand on slopes relative to the mainshock alone; thus, seismic risks are underestimated if aftershocks are neglected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20slope%20stability" title="seismic slope stability">seismic slope stability</a>, <a href="https://publications.waset.org/abstracts/search?q=mainshock" title=" mainshock"> mainshock</a>, <a href="https://publications.waset.org/abstracts/search?q=aftershock" title=" aftershock"> aftershock</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide" title=" landslide"> landslide</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20slopes" title=" flexible slopes"> flexible slopes</a> </p> <a href="https://publications.waset.org/abstracts/105496/seismic-performance-of-slopes-subjected-to-earthquake-mainshock-aftershock-sequences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105496.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">146</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">13346</span> Design and Performance Evaluation of Hybrid Corrugated-GFRP Infill Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Woo%20Young%20Jung">Woo Young Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Min%20Park"> Sung Min Park</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=Viriyavudh%20Sim"> Viriyavudh Sim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a way to reduce earthquake damage and emergency rehabilitation of critical structures such as schools, high-tech factories, and hospitals due to strong ground motions associated with climate changes. Regarding recent trend, a strong earthquake causes serious damage to critical structures and then the critical structure might be influenced by sequence aftershocks (or tsunami) due to fault plane adjustments. Therefore, in order to improve seismic performance of critical structures, retrofitted or strengthening study of the structures under aftershocks sequence after emergency rehabilitation of the structures subjected to strong earthquakes is widely carried out. Consequently, this study used composite material for emergency rehabilitation of the structure rather than concrete and steel materials because of high strength and stiffness, lightweight, rapid manufacturing, and dynamic performance. Also, this study was to develop or improve the seismic performance or seismic retrofit of critical structures subjected to strong ground motions and earthquake aftershocks, by utilizing GFRP-Corrugated Infill Panels (GCIP). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aftershock" title="aftershock">aftershock</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20material" title=" composite material"> composite material</a>, <a href="https://publications.waset.org/abstracts/search?q=GFRP" title=" GFRP"> GFRP</a>, <a href="https://publications.waset.org/abstracts/search?q=infill%20panel" title=" infill panel"> infill panel</a> </p> <a href="https://publications.waset.org/abstracts/32176/design-and-performance-evaluation-of-hybrid-corrugated-gfrp-infill-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32176.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">334</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">13345</span> Effects of Near-Fault Ground Motions on Earthquake-Induced Pounding Response of RC Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Akk%C3%B6se">Mehmet Akköse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In ground motions recorded in recent major earthquakes such as 1994 Northridge earthquake in US, 1995 Kobe earthquake in Japan, 1999 Chi-Chi earthquake in Taiwan, and 1999 Kocaeli earthquake in Turkey, it is noticed that they have large velocity pulses. The ground motions with the velocity pulses recorded in the vicinity of an earthquake fault are quite different from the usual far-fault earthquake ground motions. The velocity pulse duration in the near-fault ground motions is larger than 1.0 sec. In addition, the ratio of the peak ground velocity (PGV) to the peak ground acceleration (PGA) of the near-fault ground motions is larger than 0.1 sec. The ground motions having these characteristics expose the structure to high input energy in the beginning of the earthquake and cause large structural responses. Therefore, structural response to near-fault ground motions has received much attention in recent years. Interactions between neighboring, inadequately separated buildings have been repeatedly observed during earthquakes. This phenomenon often referred to as earthquake-induced structural pounding, may result in substantial damage or even total destruction of colliding structures during strong ground motions. This study focuses on effects of near-fault ground motions on earthquake-induced pounding response of RC buildings. The program SAP2000 is employed in the response calculations. The results obtained from the pounding analyses for near-fault and far-fault ground motions are compared with each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=near-fault%20ground%20motion" title="near-fault ground motion">near-fault ground motion</a>, <a href="https://publications.waset.org/abstracts/search?q=pounding%20analysis" title=" pounding analysis"> pounding analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20buildings" title=" RC buildings"> RC buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=SAP2000" title=" SAP2000"> SAP2000</a> </p> <a href="https://publications.waset.org/abstracts/37307/effects-of-near-fault-ground-motions-on-earthquake-induced-pounding-response-of-rc-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37307.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">262</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">13344</span> Shaking Table Test and Seismic Performance Evaluation of Spring Viscous Damper Cable System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asad%20Naeem">Asad Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinkoo%20Kim"> Jinkoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research proposes a self-centering passive damping system consisting of a spring viscous damper linked with a preloaded tendon.

Bearing in mind, the specificity of the earthquake as a load and the fact that the seismic resistance of the structures solely depends on its behaviour in the nonlinear field, traditional seismic design approach based on force and linear analysis is not adequate. “Performance-Based” seismic design method is based on nonlinear analysis and can be used in everyday engineering practice. This paper presents the application of this method to eight-story high reinforced concrete building with combined structural system (reinforced concrete frame structural system in one direction and reinforced concrete ductile wall system in other direction). The nonlinear time-history analysis is performed on the spatial model of the structure using program Perform 3D, where the structure is exposed to forty real earthquake records. For considered building, large number of results were obtained. It was concluded that using this method we could, with a high degree of reliability, evaluate structural behavior under earthquake. It is obtained significant differences in the response of structures to various earthquake records. Also analysis showed that frame structural system had not performed well at the effect of earthquake records on soil like sand and gravel, while a ductile wall system had a satisfactory behavior on different types of soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ductile%20wall" title="ductile wall">ductile wall</a>, <a href="https://publications.waset.org/abstracts/search?q=frame%20system" title=" frame system"> frame system</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20time-history%20analysis" title=" nonlinear time-history analysis"> nonlinear time-history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=performance-based%20methodology" title=" performance-based methodology"> performance-based methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20building" title=" RC building"> RC building</a> </p> <a href="https://publications.waset.org/abstracts/45616/performance-based-seismic-methodology-and-its-application-in-seismic-design-of-reinforced-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45616.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">366</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">13342</span> Statistical Physics Model of Seismic Activation Preceding a Major Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20S.%20Brox">Daniel S.

However, the recent earthquakes in the region such as the 2016 Gyeongju and the 2017 Pohang earthquake showed that the possible PGA of ground motions can be larger than 0.3g. Therefore, there is a need to analyze the seismic performance of the existing NPP structures under these earthquakes. An NPP model, APR-1400, which is designed and built in Korea was selected for a case study. The NPP structure is numerically modeled in terms of lumped-mass stick elements using OpenSees framework. The floor acceleration and displacement of components are measured to quantify the responses of components. The numerical results show that the floor spectral accelerations are significantly amplified in the components subjected to Korean earthquakes. A comparison between floor response spectra of Korean earthquakes and the NRC design motion highlights that the seismic design level of NPP components under an earthquake should be thoroughly reconsidered. Additionally, a seismic safety assessment of the equipment and relays attached to main structures is also required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nuclear%20power%20plant" title="nuclear power plant">nuclear power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=floor%20response%20spectra" title=" floor response spectra"> floor response spectra</a>, <a href="https://publications.waset.org/abstracts/search?q=Korean%20earthquake" title=" Korean earthquake"> Korean earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=NRC%20spectrum" title=" NRC spectrum"> NRC spectrum</a> </p> <a href="https://publications.waset.org/abstracts/97625/seismic-performance-of-nuclear-power-plant-structures-subjected-to-korean-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97625.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">158</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">13340</span> Effect of Irregularities on Seismic Performance of Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Snehal%20Mevada">Snehal Mevada</a>, <a href="https://publications.waset.org/abstracts/search?q=Darshana%20Bhatt"> Darshana Bhatt</a>, <a href="https://publications.waset.org/abstracts/search?q=Aryan%20Kalthiya"> Aryan Kalthiya</a>, <a href="https://publications.waset.org/abstracts/search?q=Neel%20Parmar"> Neel Parmar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vishal%20Baraiya"> Vishal Baraiya</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhruvit%20Bhanderi"> Dhruvit Bhanderi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tisha%20Patel"> Tisha Patel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In multi-storeyed framed buildings, damage occurring from earthquake ground motion generally initiates at locations of structural weaknesses present in the lateral load-resisting frame. In some cases, these weaknesses may be created by discontinuities in stiffness, mass, plan, and torsion. Such discontinuity between storeys is often associated with sudden variations in the vertical geometric irregularities and plan irregularities. Vertical irregularities are structures with a soft storey that can further be broken down into the different types of irregularities as well as their severity for a more refined assessment tool pushover analysis which is one of the methods available for evaluating building against earthquake loads. So, it is very necessary to analyse and understand the seismic performance of the irregular structure in order to reduce the damage which occurs during an earthquake. In this project, a multi-storey (G+4) RCC building with four irregularities (stiffness, mass, plan, torsion) is studied for earthquake loads using the response spectrum method (dynamic analysis) and STADD PRO. All analyses have been done for seismic zone IV and for Medium Soil. In this study effects of different irregularities are analysed based on storey displacement, storey drift, and storey shear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comparison%20of%20regular%20and%20irregular%20structure" title="comparison of regular and irregular structure">comparison of regular and irregular structure</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20analysis" title=" dynamic analysis"> dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20irregularity" title=" mass irregularity"> mass irregularity</a>, <a href="https://publications.waset.org/abstracts/search?q=plan%20irregularity" title=" plan irregularity"> plan irregularity</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20spectrum%20method" title=" response spectrum method"> response spectrum method</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness%20irregularity" title=" stiffness irregularity"> stiffness irregularity</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=torsional%20irregularity" title=" torsional irregularity"> torsional irregularity</a>, <a href="https://publications.waset.org/abstracts/search?q=STAAD%20PRO" title=" STAAD PRO"> STAAD PRO</a> </p> <a href="https://publications.waset.org/abstracts/156259/effect-of-irregularities-on-seismic-performance-of-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156259.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">75</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">13339</span> The Problems of Current Earth Coordinate System for Earthquake Forecasting Using Single Layer Hierarchical Graph Neuron</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benny%20Benyamin%20Nasution">Benny Benyamin Nasution</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahmat%20Widia%20Sembiring"> Rahmat Widia Sembiring</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Rahman%20Dalimunthe"> Abdul Rahman Dalimunthe</a>, <a href="https://publications.waset.org/abstracts/search?q=Nursiah%20Mustari"> Nursiah Mustari</a>, <a href="https://publications.waset.org/abstracts/search?q=Nisfan%20Bahri"> Nisfan Bahri</a>, <a href="https://publications.waset.org/abstracts/search?q=Berta%20br%20Ginting"> Berta br Ginting</a>, <a href="https://publications.waset.org/abstracts/search?q=Riadil%20Akhir%20Lubis"> Riadil Akhir Lubis</a>, <a href="https://publications.waset.org/abstracts/search?q=Rita%20Tavip%20Megawati"> Rita Tavip Megawati</a>, <a href="https://publications.waset.org/abstracts/search?q=Indri%20Dithisari"> Indri Dithisari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The earth coordinate system is an important part of an attempt for earthquake forecasting, such as the one using Single Layer Hierarchical Graph Neuron (SLHGN). However, there are a number of problems that need to be worked out before the coordinate system can be utilized for the forecaster. One example of those is that SLHGN requires that the focused area of an earthquake must be constructed in a grid-like form. In fact, within the current earth coordinate system, the same longitude-difference would produce different distances. This can be observed at the distance on the Equator compared to distance at both poles. To deal with such a problem, a coordinate system has been developed, so that it can be used to support the ongoing earthquake forecasting using SLHGN. Two important issues have been developed in this system: 1) each location is not represented through two-value (longitude and latitude), but only a single value, 2) the conversion of the earth coordinate system to the x-y cartesian system requires no angular formulas, which is therefore fast. The accuracy and the performance have not been measured yet, since earthquake data is difficult to obtain. However, the characteristics of the SLHGN results show a very promising answer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20graph%20neuron" title="hierarchical graph neuron">hierarchical graph neuron</a>, <a href="https://publications.waset.org/abstracts/search?q=multidimensional%20hierarchical%20graph%20neuron" title=" multidimensional hierarchical graph neuron"> multidimensional hierarchical graph neuron</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20layer%20hierarchical%20graph%20neuron" title=" single layer hierarchical graph neuron"> single layer hierarchical graph neuron</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20disaster%20forecasting" title=" natural disaster forecasting"> natural disaster forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake%20forecasting" title=" earthquake forecasting"> earthquake forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20coordinate%20system" title=" earth coordinate system"> earth coordinate system</a> </p> <a href="https://publications.waset.org/abstracts/118471/the-problems-of-current-earth-coordinate-system-for-earthquake-forecasting-using-single-layer-hierarchical-graph-neuron" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118471.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">216</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">13338</span> Lessons Learnt from Moment Magnitude 7.8 Gorkha, Nepal Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narayan%20Gurung">Narayan Gurung</a>, <a href="https://publications.waset.org/abstracts/search?q=Fawu%20Wang"> Fawu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjan%20Kumar%20Dahal"> Ranjan Kumar Dahal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nepal is highly prone to earthquakes and has witnessed at least one major earthquake in 80 to 90 years interval. The Gorkha earthquake, that measured 7.8 RS in magnitude and struck Nepal on 25th April 2015, after 81 years since Mw 8.3 Nepal Bihar earthquake in 1934, was the largest earthquake after Mw 8.3 Nepal Bihar earthquake. In this paper, an attempt has been made to highlight the lessons learnt from the MwW 7.8 Gorkha (Nepal) earthquake. Several types of damage patterns in buildings were observed for reinforced concrete buildings, as well as for unreinforced masonry and adobe houses in the earthquake of 25 April 2015. Many field visits in the affected areas were conducted, and thus, associated failure and damage patterns were identified and analyzed. Damage patterns in non-engineered buildings, middle and high-rise buildings, commercial complexes, administrative buildings, schools and other critical facilities are also included from the affected districts. For most buildings, the construction and structural deficiencies have been identified as the major causes of failure; however, topography, local soil amplification, foundation settlement, liquefaction associated damages and buildings built in hazard-prone areas were also significantly observed for the failure or damages to buildings and hence are reported. Finally, the lessons learnt from Mw 7.8 Gorkha (Nepal) earthquake are presented in order to mitigate impacts of future earthquakes in Nepal. <p class="card-text"><strong>Keywords:</strong> <a
