随着城市建设的发展,对于临街的住宅和办公楼,一般均要求在底层设置商店。然而,此类柔性底层房屋的抗震性能很差,地震时底层的破坏程度很重。通过对震害规律、模型试验以及理论计算结果的分析,我们认为,在进行底层为大空间的多层房屋的抗震设计时,应在以下几方面加以改进:1. With the development of urban construction, it is generally required to set up shops on the ground floor for residential and office buildings facing the street. However, the anti-seismic performance of such flexible subgrade housings is poor, and the underlying damage during earthquakes is very heavy. Through the analysis of earthquake damage laws, model tests, and theoretical calculations, we believe that in the seismic design of a multi-storey house with a large ground floor, improvement should be made in the following aspects: 1.
