| 摘 要： | 在四川汶川地震中,一些混凝土框架结构没有出现＂强柱弱梁＂的破坏机制,而是在柱端出现塑性铰,柱发生剪切破坏。基于中国抗震规范对柱构件设计的要求,通过对柱的破坏形式和原因分析,进行框架柱的设计时要充分考虑各因素的影响,建议框架结构的设计应适当提高柱的刚度和承载力,结构弹塑性分析时应采用有楼板和填充墙的计算模型来代替纯框架结构计算模型。

| Abstract: | Some concrete frame structures were not damaged with "strong column and weak beam",but plastic hinges formed at column ends in Wenchuan earthquake.Based on the requirement of designing column in China seismic code,We must fully consider the various factors of frame column,and the suggest is that the stiffness and strength of columns need be enhanced,and structural elastic-plastic analysis model should take slab and infill wall into account instead of pure frame structural analysis model. |
