摘要:
提出一种新型的钢框架结构体系,即内摇摆柱-钢框架结构体系.为了研究这种新体系的受力性能,并与普通钢框架体系性能相比较,本文建立了六层的新型结构体系和传统普通钢框架体系的三维非线性有限元模型,分析了在不同类型的侧向荷载作用下结构的变形特征、承载力以及塑性铰分布等受力性能,结果显示本文提出的内摇摆柱-钢框架结构体系具有良好的受力性能,并且新型结构体系构造简单施工方便,采用该体系建筑结构可以获得较好的经济效益
Abstract:
A new structure system that i.e. a multi-storey steel moment frame combined with interior leaning columns and hinged beams(MFCLC)is put forward in this paper. To research the behavior of this structure system under lateral loads, two analytical six-storey steel buildings are designed, an un-braced steel moment frame(MF),and an MFCLC. Three-dimension finite element method is used to analyze the two structural models. Ultimate bearing capacities of the two models subjected to three different distribution types’ lateral loads are studied and compared. The results showed that the new structural system has similar or even better performance than the pure steel moment frames in the case where the volume of the steel is not increased. In addition, as a result of reducing a large number of steel beam-column rigid connections, the MFCLC can reduce the configuration volume of the steel in total beam-column connections. Steel frames with more flexible beam-to-column connections also have many economical and construction advantages over rigid frames
