[摘要] 以光谷网球中心15000座网球馆为对象，对主体结构及大跨度空间结构的抗连续倒塌性能进行了研究。首先通过基于概念判断的敏感性分析方法，确定每类构件中最关键的杆件；再依次对网球馆的Y形柱，顶部环梁，电梯处格构柱钢管，固定屋盖支撑，圆钢管大拱，菱形网格撑杆采用线性静力拆除构件法进行抗连续倒塌分析。分析结果表明15000座网球馆具有良好的抗连续倒塌性能，并提出增强结构整体性的措施。

Abstract: Tennis Court with 15000 seats of The Optics Valley Tennis Center was analyzed to estimate the progressive collapse of the main building structures and long-span space structures. Firstly the sensitivity analysis method was used to choose the important components of a class structure member based on conceptual estimate. Then linear static alternative load path method was applied for the progressive collapse prevention analysis of the Y shape columns, the top ring beams, the steel pipes of latticed columns, the braces of fixed roof, the steel tubular arch and the braces of rhombic-shaped steel grid. It can be concluded that the main building structure and roof structure of the Tennis Court with 15000 seats has good resistance to progressive collapse, so the reinforcement measures are proposed．
Keywords: Optics Valley Tennis Center; resist progressive collapse; alternative load path method
