摘要:
提出在垂直升降型立体车库承重骨架的四边形筒式钢构架结构中设置一定间距的横隔,形成带横隔的立体停车结构,以提高结构的整体性。利用有限元软件SAP2000建立了结构分析模型,通过对不同横隔设置方案的结构静力性能,即中间框架的侧移和内力分布、停车区间和提升井变形的比较,探讨了横隔对结构性能的影响及横隔设置的最佳方案。结果表明:设置横隔能加强结构整体性,有效保证中间框架与边框架的同步侧移且显著减小中间框架侧移,结构停车区间和提升井的变形得到有效控制,利于车辆停放及设备的运行,同时柱内力突变相对缓和;综合考虑制作成本及结构性能情况,间隔3层设置横隔为最佳方案。
Abstract:
A tridimensional parking structure with diaphragms was presented by setting diaphragms at some levels of the quadrangular tubetype steel frame. A structural analysis model was established by finite element software SAP2000. By comparing the static property of the structures with different diaphragm arrangement schemes, the effects of diaphragms on structural optimum properties, including the lateral displacement and internal force distribution of the middle frame and the deformation of the parking areas and lifting areas, were studied. Meanwhile, the optimal arrangement scheme of diaphragms was investigated. Results indicate that the behavior of the quadrangular tubetype steel frame tridimensional parking structure is significantly improved for the diaphragms. Besides, the storey shifts of the middle frame become smaller and more uniformly, the deformation of the parking areas and lifting areas is effectively restrained, which is conducive to parking of vehicles and operation of the lifting equipment. Moreover, the sudden change of column internal forces becomes relatively moderate. Synthesizing the cost and structural behaviors, arranging diaphragms every four storeys is the optimal scheme.
