在水平地震力作用下,钢筋混凝土框架结构多层房屋的底层,有时侧移变形较大而不满足规范所规定的变形限值的要求。为此仅在房屋底层设置一定数量的抗震墙,形成底层加抗震墙的框架结构房屋。本文对这种结构的性能作了分析,提出了初步的计算方法及一些构造措施。 Under the action of horizontal seismic forces, the bottom layer of a multi-story reinforced concrete frame structure sometimes deforms laterally and does not meet the requirements of the deformation limits specified in the specifications. For this purpose, only a certain number of seismic walls are installed on the ground floor of the house to form a frame structure housing with a seismic wall at the bottom. This article analyzes the performance of this structure and proposes a preliminary calculation method and some structural measures.
