由于场地限制和建筑物功能的需要，地震区所建的高层建筑往往难以满足规范关于“平、立面宜规则对称”的要求，是否需要设置防震缝一直是建筑师与结构师争议的焦点。本文从历次震害现象和理论分析两方面对该问题进行了研究，并对复杂体型高层建筑的抗震概念设计提出了若干建议． Due to the site constraints and the need for building functions, high-rise buildings built in seismic areas are often difficult to meet the requirements for regulating the “symmetry between the elevation and the facade.” Whether or not earthquake-proof joints need to be installed has always been the focus of disputes between architects and architects. This paper studies the problem from two aspects of earthquake damage phenomena and theoretical analysis, and puts forward some suggestions for the seismic concept design of complex tall buildings.
