一、前言本文对高层框剪结构体系中含墙量与结构动力特性之间的关系和变化规律进行了探讨,总结了框剪结构中的剪力墙在地震时所起的作用.国内外历次地震表明,框架加剪力墙的结构体系抗震性能比较好,是当前我国中高层房屋采用的主要结构形式之一.框剪体系剪力墙量究竟采用多少,才能使结构达到既安全又经济、既能满足强度要求,又能满足位移的限制值.我国过去一股是参考日本提
I. INTRODUCTION This paper discusses the relationship and variation law between wall content and structural dynamic characteristics in high-rise frame-shear structural systems, and summarizes the role of shear walls in frame-shear structures during earthquakes. The earthquake shows that the seismic performance of the frame and shear wall structural system is relatively good. It is one of the main structural forms adopted by middle and high-rise houses in China. How much shear wall system should be used in order to make the structure safe and economical? Can meet the strength requirements, but also meet the displacement limit value. China’s past is a reference to Japan
