设置加强层的钢框架-核心筒结构的动力弹塑性时程分析
The dyna mic ti me-history analysis of steel fra me-core tube structure with strengthened layer
摘要
Abstract
In order to study the effect of horizontal strengthened layer on the steel frame-core tube structure un-der earthquake action,a 34 layer steel frame-core tube built without strengthen layer and with one,two,three reinforcing strengthened layers was selected to evaluate the dynamic elastic -plastic time -history effect. Through calculation,the floor displacement response and the distribution of plastic hinges of four kinds of struc-tures under seismic principal direction of 7 degrees,8 degrees,9 degrees of rare earthquake were derived.The effect of aseismic performance on structures with different numbers of strengthened layers has been comprehen-sively analyzed.The results show that setting the strengthening layer can improve the stiffness of the structure, and the seismic effect of two strengthened layers is better than that with one or three reinforcing layers.关键词
