[提要]  應(yīng)用ANSYS軟件對(duì)廣州市新體育館主場(chǎng)館鋼屋蓋結(jié)構(gòu)進(jìn)行了安裝過程的動(dòng)態(tài)跟蹤分析。跟蹤分析的主要目的是實(shí)時(shí)了解吊裝和拆撐兩個(gè)階段鋼屋蓋內(nèi)力和變形的變化情況，并根據(jù)分析結(jié)果復(fù)核、優(yōu)化施工吊裝方案和拆撐方案。計(jì)算分析為鋼屋蓋安裝提供了理論依據(jù)。

Based on the ANSYS finite element nonlinear analysis, this paper presents the continuous changing of deformation and internal force distribution of truss roof structure of Guangzhou New Gymnasium during its erection process. The emphasis is paid on the theoretical investigation to safety behavior of the roof structure from hoisting state into design state after removing temporary pillars. The proposed erection scheme were checked theoretically, and some modifica-tions were made accordingly.
Keywords:  steel truss; roof structure; tracing analysis; hoisting; removing; temporary pillars; process
