Effects of ground motion spectral characteristics on RC frame fragility considering liquefaction [PDF]
Scientific ReportsSeismic liquefaction represents a persistent and complex engineering challenge in soil dynamics. Post-earthquake damage investigations have shown that damage to buildings caused by site liquefaction constitutes a significant proportion of all seismic ...

Quantitative bounded method of special long-period ground motions
Magazine of Civil Engineering, 2022 The resonance effect of special long-period ground motions to (super) high-rise buildings is significant, which is likely to cause serious damage to these long-period structures. Therefore, the influence of long-period ground motions cannot be ignored in

NGA-West2地震动预测模型对速度脉冲型地震动各分量的适用性
Dizhen xuebao, 2023 鉴于传统的地震动预测模型未考虑速度脉冲的影响，可能会低估近断层区域的地震风险，而新一代NGA-West2地震动预测模型对速度脉冲型地震动的适用性有待研究。首先，收集了2013年以来的近断层地震动记录，在充分考虑脉冲方向的不确定性条件下，基于小波方法定量地识别出速度脉冲记录，形成了最新的速度脉冲记录数据库；然后，利用小波提取出速度脉冲记录中的长周期脉冲信号，基于偏差参数分析方法，定量地研究NGA-West2地震动预测模型分别对速度脉冲原始记录和提取长周期脉冲后的残余记录的适用性。研究结果显示，NGA ...

Correlation of Ground Motion Duration with Its Intensity Metrics: A Simulation Based Approach [PDF]
Journal of Soft Computing in Civil Engineering, 2020 There are different kinds of intensity measures to characterize the main properties of the earthquake records. This paper proposes a simulation-based approach to compute correlation coefficients of motion duration and intensity measures of the earthquake

Seismic Response Analysis of a Curved Bridge under Near-Fault and Far-Field Ground Motions
Applied Sciences, 2022 To study the influence of near-fault and far-field (FF) ground motions on a curved girder bridge, a 1:10 scale curved bridge shaking table test model was constructed. Three types of ground motions, namely, near-fault pulse (NP), near-fault non-pulse (NN),
