[摘要] 以光谷網(wǎng)球中心15000座網(wǎng)球館為對象，對主體結(jié)構(gòu)及大跨度空間結(jié)構(gòu)的抗連續(xù)倒塌性能進行了研究。首先通過基于概念判斷的敏感性分析方法，確定每類構(gòu)件中最關(guān)鍵的桿件；再依次對網(wǎng)球館的Y形柱，頂部環(huán)梁，電梯處格構(gòu)柱鋼管，固定屋蓋支撐，圓鋼管大拱，菱形網(wǎng)格撐桿采用線性靜力拆除構(gòu)件法進行抗連續(xù)倒塌分析。分析結(jié)果表明15000座網(wǎng)球館具有良好的抗連續(xù)倒塌性能，并提出增強結(jié)構(gòu)整體性的措施。

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
