摘要
重庆龙兴足球场主体结构采用设置少量剪力墙的框架结构,屋盖钢结构采用悬挑平面桁架+上下弦稳定支撑+立面单层网格结构.为了研究结构设计的难点,采用了SPASCAD-PMSA、MIDAS Gen(Ver.2019)和SAP2000 设计软件分别对结构进行多遇地震下的抗震性能分析.采用了SAUSAGE、SAP2000 软件对结构进行设防、罕遇地震下的抗震性能分析.采用了ANSYS软件对钢屋盖整体稳定进行分析,采用了ABAQUS软件对节点受力性能进行分析.结果表明:结构具有较好的抗震能力和抗连续倒塌能力,结构设计安全、合理、经济.
Abstract
The main structure of Chongqing Longxing Football Stadium adopts a frame structure with minor shear walls.The roof steel structure adopts a cantilever plane truss+upper and lower string stable support+single-layer grid structure.In order to study the difficulties of structural design,SPASCAD-PMSA,MIDAS Gen(Ver.2019)and SAP2000 design softwares were used to analyze the seismic performance of the structure under frequent earthquake.SAUSAGE and SAP2000 softwares were used to analyze the seismic performance of the structure under fortification and rare earthquake.ANSYS software was used to analyze the overall stability of the steel roof,and ABAQUS software was used to analyze the mechanical properties of the joints.The results show that the structure has good seismic capacity and progressive collapse resistance,and the structural design is safe,reasonable and economical.
