ABSTRACT

In densely-populated cities, complex site-city interaction (SCI) effects can occur and may result in non-negligible influences on the input motions to buildings. Due to its complexity, topographic amplification has not yet been considered in most SCI investigations, particularly in experimental tests. This study conducted seven sets of shaking table tests incorporating complex terrains. The SCI effects induced by different terrains, building frequencies, building configurations, and input motions were investigated. Based on the test results, the reliability of a previously proposed numerical coupling scheme was validated. Finally, through a parametric analysis and a case study, the SCI effects were further illustrated.

摘要

在人口稠密的城市中，可能会发生复杂的站点-城市交互 (SCI) 效应，并且可能会对建筑物的输入运动产生不可忽略的影响。由于其复杂性，在大多数 SCI 研究中尚未考虑地形放大，特别是在实验测试中。本研究进行了七组包含复杂地形的振动台测试。研究了由不同地形、建筑物频率、建筑物配置和输入运动引起的 SCI 效应。基于测试结果，验证了先前提出的数值耦合方案的可靠性。最后，通过参数分析和案例研究，进一步说明了SCI的影响。
