型钢混凝土框支框架-混凝土核心筒结构抗震性能分析
|
摘要
对带型钢混凝土梁式转换层的型钢混凝土框支框架-混凝土核心筒结构进行有限元计算分析,研究了转换层设置高度及转换层上、下等效侧向刚度比变化时,其地震作用下结构地震反应的一般规律.结果表明,此类结构的转换层设置高度可适当提高,适合高位转换;抗震设计时,对转换层附近外框架应予以加强,对于高位转换,应重点加强转换层上一层外框架;设计转换层上1～2层的外框架时,相对其它框架柱,应强化框支柱;转换层上、下结构等效侧向刚度比宜控制在0.86～1之间.
A finite element analysis was conducted on steel reinforced concrete frame supported by frame-concrete core structure with steel reinforced girder transfer story,and the general rules of the earthquake response were studied,when the height of transfer story and the ratio of equivalent lateral stiffness change.The results have shown that the height of transfer story can be set a little higher properly and suitable at a high altitude,and the outer frame should be reinforced around the transfer story for seismic design.When the transfer story is at a high altitude,the outer frame,up but next to the transfer story,should be specially strengthened,and when designing the outer frame of one or two upper stories,the corner columns should be more reinforced than other columns.Besides,the ratio of equivalent lateral stiffness should be ranged between 0.86 and 1.
