地震作用下钢筋混凝土联肢剪力墙的应力分析

摘要

应用有限元分析软件ANSYS,分析了某钢筋混凝土联肢剪力墙在水平地震作用下的应力分布情况,研究得出：位于整片墙体底部及中部的洞口边角处表现出了明显的应力集中,控制连梁的跨高比,不仅可以避免连梁本身发生剪切破坏,而且可使其两侧墙肢仍具有较强的抗震能力。%Application of finite element analysis software ANSYS,the paper analyzes the distribution of stress in a reinforced coupled shear wall under horizontal earthquake action.It is concluded that： the hole corner in bottom and middle of the whole piece wall show significant stress concentration,when control the span-depth ratio of coupling beam,not only to avoid shear failure of itself,but also to allow the wall limb which in both sides of coupling beam still have strong seismic capacity.
