【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]:In order to improve the integrity of the structure, it is put forward that a certain spacing is set up in the quadrilateral steel frame structure of the vertical lifting solid garage bearing frame, and the three-dimensional parking structure with the horizontal space is formed. The finite element software SAP2000 is used to establish the structural analysis model. By comparing the static behavior of the structure with different lateral separation schemes, that is, the lateral displacement and internal force distribution of the middle frame, the deformation of the parking area and the hoist shaft, a comparison is made between the static behavior of the structure and the displacement of the hoisting well. The influence of the transversal on the structure performance and the optimum scheme of the transversal arrangement are discussed. The results show that the structure integrity can be strengthened by setting the horizontal barrier, the synchronous lateral shift of the intermediate frame and the side frame can be effectively guaranteed, and the lateral displacement of the intermediate frame can be significantly reduced, and the structural parking area and the deformation of the hoisting well can be effectively controlled. It is beneficial to the parking of vehicles and the operation of equipment, while the sudden change of internal force in the column is relatively mild; Considering the production cost and structure performance, the best plan is to set 3 layers of horizontal septum.
