摘要

在四川汶川地震中一些混凝土框架结构出现"强梁弱柱"的破坏机制,柱发生剪切破坏,最终导致结构形成侧移机构。通过对"强梁弱柱"框架破坏过程分析,以及考虑随机多维地震作用下框架的受力特性,并与中国规范进行对比,为完善框架结构抗震设计提供参考。
Some concrete frame structures were damaged with "strong beam and weak column",and plastic hinges formed at column ends earlier than beam ends.Then structures are collapsing by shear breakdown in columns.Through analysis for the reasons the RC frame structure in multidimensional earthquake,and comparing with code for seismic design of building.the suggestion proposed are essential to consummate the seismic design.
