ABSTRACT

The regional seismic damage assessment methods based on time-history analysis usually ignore the site-city interactions (SCI). The SCI may influence the simulated seismic responses and damage states of buildings. However, very few studies have been conducted to quantify the SCI effects on the damage states of buildings. In this study, the SCI effects on the seismic damage of buildings were quantitatively analysed using an idealized building arrangement model and several real-world urban models. The results show that the SCI effects on the regional damage ratios are limited, especially for urban areas with various building types and irregular arrangements.

摘要

基于时程分析的区域地震损伤评估方法通常忽略了站点-城市相互作用（SCI）。SCI 可能会影响模拟的地震响应和建筑物的损坏状态。然而，很少有研究来量化 SCI 对建筑物损坏状态的影响。在这项研究中，使用理想的建筑布置模型和几个现实世界的城市模型，定量分析了 SCI 对建筑物地震破坏的影响。结果表明，SCI对区域破坏率的影响是有限的，尤其是对于建筑类型多样、布置不规则的城市地区。
