摘要
五、六十年代建成的大型公共建筑，不少都由变形缝分成各自独立的区段，但缝宽均不能满足现行抗震规范对防震缝最小宽度的要求，地震时相邻区段可能互撞导致严重破坏甚至倒塌。本文通过几个具体实例，对这些建筑物地震时碰撞问题进行探讨，提出一些具体的措施，供建筑工程技术人员参考。
Some large public buildings built in the 1950's or the 1960's were usually separated into several division by deformation joints,but their width can not meet the provision of seismic joint in the aseismic code.In this case,the adjacent parts may be pounded and destroyed seriously or even collapsed during earthquake.In this paper,the problems of seismic pounding effects of existing buildings are probed by analyzing a few examples,and some details against pounding are put forward,which may serve as a reference for engineering technicians.
