横向钢梁空间约束作用对钢框架-混凝土核心筒结构弹塑性地震反应的影响
|
摘要
本文基于文献[5]建立的钢框架-混凝土核心筒混合结构弹塑性地震反应的拟三维分析模型,进一步考虑钢框架和核心筒之间横向梁的空间扭转作用,讨论了横向梁空间约束作用对钢框架-混凝土核心筒混合结构弹塑性地震反应的影响。算例分析表明:进一步考虑横向梁的空间扭转作用后所得的楼层位移和层间位移角比只考虑竖向作用所得的值偏大,可见,采用考虑横向梁空间竖向和扭转约束作用的拟三维分析方法更合理。
Based on the pseudo-three-dimensional elastic-plastic seismic response analysis model of the steel frame concrete tube hybrid structures established by Reference [5],this paper further considers the reverse restraining effects of the transverse beam between steel frame and concrete.Then the effects of transverse beam's reverse restraining on the elastic-plastic seismic response of steel frame-concrete tube hybrid structures are discussed.Examples show that the inter-story displacement and the story drift which considers the reverse restraining effects are bigger than those got in Reference [5].It is found that the pseudo-three-dimensional analysis method which considers both of the vertical restraining and reverse restraining is more reasonable.
