［摘要］霍爾果斯文體中心文化館屋蓋采用鋼網(wǎng)架結(jié)構(gòu)，網(wǎng)架右側(cè)為大懸挑結(jié)構(gòu)，左側(cè)為復(fù)雜的扭轉(zhuǎn)體型網(wǎng)架并支撐在科技館混凝土邊柱及邊梁上，形成復(fù)雜的連體網(wǎng)架。采用有限元分析軟件建立整體模型及獨立的網(wǎng)架模型進行對比計算，分析了兩種模型的動力性能； 采用時程分析法對比兩種模型在地震作用下支座位移的差異； 最后進行了整體模型罕遇地震下彈塑性時程分析。得到整體模型的振動周期較長且支座位移較大，確定了罕遇地震下支座處的位移量，并用于指導(dǎo)滑動支座的設(shè)計。

Abstract:The Culture Center′s roof of the Horgos Culture & Sport Center is constructed with a steel grid structure, with the right side of the frame being a large cantilevered structure and the left side of the frame being a complex torsional grid supported on the concrete side columns and beams of the Science and Technology Museum, forming a complex connected grid. The finite element analysis software was used to establish the overall model and the independent model of the grid structure for comparison calculation, and the dynamic performance of the two models was analyzed; the difference of pedestal′s displacement between the two models under the action of earthquake was compared by time history analysis method; Finally, the elastic-plastic time history analysis of the overall model under rare earthquake was carried out. Come to the conclusion: The vibration period of the overall model is longer and the pedestal′s displacement is larger. The result of pedestal′s displacement under rare earthquake was determined and used to guide the design of sliding pedestal.
Keywords:connected grid; large cantilevered structure; sliding predestal; elastic-plastic time history analysis
