摘要
巨型框筒-钢子框架结构是一种新型的结构体系,本文以1栋48层巨型框筒-钢子框架结构为例,运用Midas软件建立三维空间有限元模型,并进行了模态分析,考查了该结构的自振特性;并改变该结构各构件刚度、质量等关键参数,采用弹性时程分析方法,研究了子结构、巨型框架、核心筒刚度的变化对结构动力特性的影响.研究表明巨型框筒-钢子框架结构具有良好的抗震性能,并给出了参数影响规律.
Mega frame tube-steel subframe structure is one kind of new structure system.This article takes one 48 mega frame tube-steel subframe structure as an example,the Midas software is used to establishe the three-dimensional space finite element model.It has carried on the modality analysis and examined the self oscillation characteristic of this structure.By changing the essential parameter of this structure,such as various components rigidity,the quality and so on,the elastic time interval analysis method is applied to research this structure's dynamic characteristics influence,which is caused by changing the sub-structure,giant frame,core tube rigidity.The results of the example in this paper show that mega frame tube-steel subframe structure has the good earthquake resistance performance and the rules of the parameters influence is also listed.
