ABSTRACT

What is the probability of collapse of tall steel braced frame buildings under San Andreas earthquakes in the next 30 years? Using more than 38000 ground motion histories from simulations of 60 scenario earthquakes on the San Andreas fault with magnitudes in the range of 6–8, 3-D nonlinear analysis of several variants of an 18-story steel braced frame building is conducted to address this question. Results are combined with the 30-year probabilities of the scenario earthquakes using the PEER performance-based earthquake engineering framework to determine the exceedance probabilities of five performance limit states over the next 30 years.

使用 Rupture-To-Rafters 模拟对高层钢支撑框架建筑的性能量化

摘要

未来 30 年圣安地列斯地震下高层钢支撑框架建筑倒塌的概率是多少？使用来自圣安德烈亚斯断层上 60 次场景地震模拟的 38000 多个地面运动历史，震级范围为 6-8，对 18 层钢支撑框架建筑的几种变体进行 3-D 非线性分析以解决这个问题问题。使用基于 PEER 性能的地震工程框架将结果与情景地震的 30 年概率相结合，以确定未来 30 年五个性能极限状态的超过概率。
