［摘要］深圳坪山體育館屋頂采用新穎的弦支穹頂結(jié)構(gòu)體系。弦支穹頂是一種剛?cè)犭s交的預(yù)應(yīng)力鋼結(jié)構(gòu)體系,實(shí)際工程應(yīng)用較少,施工經(jīng)驗(yàn)不足,因此針對(duì)此結(jié)構(gòu)施工全過(guò)程的計(jì)算模擬分析顯得十分重要。結(jié)合工程特點(diǎn)，充分考慮施工實(shí)際條件,選定施工方案和施工張拉順序,對(duì)預(yù)應(yīng)力張拉整體結(jié)構(gòu)施工全過(guò)程進(jìn)行有限元模擬計(jì)算，分析了預(yù)應(yīng)力張拉過(guò)程中結(jié)構(gòu)的變形、內(nèi)力變化規(guī)律，確保了張拉施工過(guò)程中結(jié)構(gòu)的安全。

Abstract:Suspend-dome structure is adopted in Pingshan Basketball Gymnasium for Universidad 2011 Shenzhen. The suspend-dome is a prestressed structural system with the combination of rigid-flexible. Due to the less of actual projects and the lack of construction experience, the analysis of the whole construction simulation for the roof would be much important. Focused on the features of the project, considering the actual condition of the constrution, the constuction plan and the tension sequence were chosen, and the prestressed construction simulation analysis was carried out through finite element calculation.The laws of member force and deformation evolution were achieved from the analysis, which would be used to make sure the safty of the construction process.

Keywords:sing-layer reticulated dome; suspend-dome structure; cable-bar structure system; tension construction; the whole construction simulation
