摘要:
在一些假定的基础上,运用结构动力学关于分布参数体系的振动理论,考虑核心筒变刚度和加强层弯曲变形的影响,对带有水平加强层体系的高层框架-核心筒结构进行动力分析,编制了计算机算法程序,并根据核心筒与外排柱刚度之比、核心筒与水平加强层刚度之比以及加强层位置以上部分核心筒与加强层位置以下部分核心筒刚度之比的不同取值,得出了该体系前3阶振型频率与加强层位置的关系,为合理设计加强层提供了参考。
Abstract:
Based on some assumptions, the free vibration frequency of the structures with an outrigger was analyzed. And depended on different values of the stiffness ratio of core-column, the stiffness ratio of core-outrigger and the stiffness ratio of tube, the relation between the location of the outrigger and the free vibration frequency was inferred through a computer program. The equal-parameter distribution theory of the structural dynamics was used and the influences of core wall with changing stiffness and outrigger flexure were considered. The results give some reference for rationaloutrigger designing.
