Optimal Seismic Intensity Measure Selection for Isolated Bridges under Pulse-Like Ground Motions

open access: yesAdvances in Civil Engineering, 2019
Isolated bridges are commonly designed in the near-fault region to balance excessive displacement and seismic force. Optimal intensity measures (IMs) of probabilistic seismic demand models for isolated bridges subjected to pulse-like ground motions are ...

Modeling response spectrum compatible pulse-like ground motion [PDF]

open access: yesMechanical Systems and Signal Processing, 2022
The seismic response analysis of near-fault pulse-like ground motions is severely restricted due to the scarcity of pulse-like records. The requirement in regulations that the response spectra of artificial ground motions should be compatible with the ...

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

open access: yesDizhen 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 ...

A light-triggered Time-Resolved X-ray Solution Scattering (TR-XSS) workflow with application to protein conformational dynamics. [PDF]

open access: yesFEBS Open Bio
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
