【摘要】 巨型框架结构由于具有良好的建筑适用性和潜在的高效结构性能,正越来越受到建筑工程的广泛应用。文章运用有限元软件SAP2000,对随着主框架梁数量增加而均匀布置的几种巨型框架结构进行线性时程分析,比较几种巨型框架结构的抗震动力响应。计算结果表明,当巨型梁数量增加并均匀布置时结构周期减小,楼层侧移减小,但楼层剪力会增大,巨型梁布置增大了结构刚度,因此结构设计时应合理布置巨型梁,从而增强结构抗震性能。更多还原

【Abstract】 Because of good applicability and high potential structural performance,Mega-frame structure is more and more widely used in constructions.Using the finite element software SAP2000,this paper analyzed linear time-history of several kinds of Mega-frame Structures in which the mega beams were distributed uniformly with the increase amount.Then compare the seismic response behavior of these Mega-frame Structures.The results show that the structural period and floor displacement were decreased,and the floor sheer was increased with the increase of beam amount and its uniform distribution.At the same time,rigidity of structure was increased with the layout of main frame beams.To enhance seismic behavior of structure,mega beams should be distributed reasonably while designing structures.更多还原
