摘要
瑞金体育中心体育场是一座综合性体育场馆。东西看台屋盖主要通过下部混凝土柱和环向平台梁支撑,屋盖悬挑部分采用双向斜交折形平面桁架结构,立面部分则由双向斜交折形平面桁架汇总形成梭型倒三角桁架支承于环向平台梁。通过总装模型分析整体结构在静力荷载、温度、地震等作用下的受力性能分析,进行了抗连续性倒塌分析和复杂节点设计,结果表明结构具备较好的安全储备和抗连续倒塌能力,供类似工程设计参考。
Ruijin sports center stadium is a comprehensive stadium.The roof of the east and west stands were mainly supported by the lower concrete columns and the platform beams,the cantilever part of the roofs are made up of a two-way oblique plane truss structure and the vertical part is formed by the two-way oblique plane truss.Through the analysis of the overall structure of assembly model under static load,temperature,earthquake and other mechanical performance,the continuity resistance collapsed and the complex node were designed,analysis results show that the structure has good security reserve and continuous collapse resistance,which can provide the reference for the similar engineering design.
