摘要: 汕頭亞青會場館項目(一期)位于沿海強風(fēng)、臺風(fēng)易發(fā)的高烈度地區(qū),鋼屋蓋采用倒三角立體懸臂桁架+拱桁架的結(jié)構(gòu)體系,存在結(jié)構(gòu)跨度大、懸挑大、風(fēng)振響應(yīng)、溫度效應(yīng)明顯等設(shè)計難點. 從結(jié)構(gòu)體系、設(shè)計條件、力學(xué)概念出發(fā),通過傳力路徑分析、溫度作用精細(xì)分析、振動分析、防連續(xù)倒塌分析等,最終采用柱內(nèi)預(yù)應(yīng)力拉索、彈簧阻尼支座、調(diào)諧質(zhì)量阻尼器、現(xiàn)場溫度監(jiān)測等措施解決結(jié)構(gòu)振動、溫度效應(yīng)等問題. 分析結(jié)果表明,鋼結(jié)構(gòu)體系合理,抗震和抗風(fēng)性能好,結(jié)構(gòu)整體性強.

Abstract: The venue project Shantou Asian Youth Conference ( phase I) is located in a high-intensity area with strongcoastal winds and typhoons, the steel roof adopts the structural system of inverted triangular three-dimensional cantilevertruss + arch truss. There are design difficulties such as large structural span, large overhang, wind vibration response andobvious temperature effect. Starting from the structural system, design conditions and mechanical concepts, through theanalysis of force transfer paths, fine analysis of temperature effects, vibration analysis and anti-continuous collapseanalysis, etc. , finally, prestressed cables in the column, spring damping bearings, tuned mass dampers, on-sitetemperature monitoring and other measures were adopted to solve problems of structural vibration and temperature effects.The results show that the steel roof structure system is reasonable, the seismic and wind resistance performance is good, thestructural integrity is strong.
Keywords: venue project Shantou Asian Youth Conference; prestressed cable in column; spring damping bearing;temperature analysis; anti-continuous collapse; tuned mass damper
