摘要
根据结构抗震设计规范,分别采用精细时程积分法和结构分析软件Midas/gen建模,对高层钢框架-混凝土核心筒的混合结构的动力特性和地震时程反应进行分析,得到自振周期及地震作用下的位移和加速度响应.通过对比可知精细时程分析方法和Midas/gen两种不同建模方法得到的计算结果吻合较好,说明精细积分分析方法和Midas/gen的分析方法都是适用可靠的,均能为此类结构的抗震性能研究提供有效的途径.
According to the present code for seismic design of building,the characteristics of free-vibration and the time history of seismic performance of steel-concrete hybrid structure were carried out by using precise time integration method and Midas/gen software,the characteristics of free-vibration,the displacement and acceleration distribution were obtained.The comparison of the results shows that the analysis results of precise time-history analysis methods are in good agreement with two different Midas/gen methods.It is indicated that precise time-history analysis methods and two different Midas/gen methods are the reliable ways to study the seismic performance of the structure.
