Synergistic combination of systems for structural health monitoring and earthquake early warning for structural health prognosis and diagnosis [PDF]

open access: yes, 2012
Earthquake early warning (EEW) systems are currently operating nationwide in Japan and are in beta-testing in California. Such a system detects an earthquake initiation using online signals from a seismic sensor network and broadcasts a warning of the ...

Seismic hazard analysis for engineering sites based on the stochastic finite-fault method

open access: yesEarthquake Science, 2022
Seismic hazard analyses are mainly performed using either deterministic or probabilistic methods. However, there are still some defects in these statistical model-based approaches for regional seismic risk assessment affected by the near-field of large ...

Assessment of the earthquake vulnerability of multi-residential buildings in Slovenia

open access: yesActa Geographica Slovenica, 2009
The paper assesses the earthquake vulnerability of multi-residential buildings in Slovenia, although it is limited to the buildings that were built before 1981, in the time when the earthquake building codes were much less elaborated than today.

近断层速度脉冲型地震动纵向输入下综合管廊振动台试验

open access: yesDizhen xuebao
基于振动台试验,探讨了速度脉冲对综合管廊动力响应的影响,重点阐明了地震动速度脉冲特性如何影响综合管廊和周围土壤的地震行为。选取具有速度脉冲的实际地震动记录和合成的与实际地震动记录具有相同反应谱的无速度脉冲地震动时程,同时将其加速度幅值分别调整为0.10g,0.20g,0.30g作为输入,设计并开展了地震动纵向输入下的综合管廊振动台试验。基于试验数据分析了场地土体的地震反应变化规律、综合管廊结构的地震响应特征和土-结构相互作用效应。研究结果表明:① 土体在连续试验加载下结构发生变化 ...
