［摘要］煙臺八角灣國際會展中心AC廳結(jié)構(gòu)采用大跨度鋼框架結(jié)構(gòu)體系，屋面采用平面桁架結(jié)構(gòu)體系，屋蓋呈波浪形，展廳屋蓋平面投影最大長度約360m，最大寬度約270m，存在多項不規(guī)則項，屬于超限結(jié)構(gòu)。主要介紹了AC廳的設(shè)計思路，采用YJK和MIDAS Gen兩種軟件對結(jié)構(gòu)進行了多遇地震作用下的整體計算，并采用彈性時程分析法進行補充驗算；采用性能化設(shè)計方法保證主要構(gòu)件在設(shè)防地震和罕遇地震作用下的性能要求；采用3D3S及MIDAS Gen軟件對屋蓋桁架結(jié)構(gòu)進行分析，控制結(jié)構(gòu)變形及應(yīng)力比；對關(guān)鍵節(jié)點補充有限元分析計算。分析結(jié)果表明，設(shè)計方案合理、結(jié)構(gòu)安全可靠。

Abstract: No.AC exhibition hall in Yantai Bajiaowan International Convention and Exhibition Center adopts long-span steel frame structure system, and its roof adopts plane truss structure system, and the roof is undulating. The maximum plane projection length of the roof is 360 meters and width is 270 meters respectively. There are many irregular terms, which belong to out-of-code structure. The design ideas of No.AC exhibition hall were mainly introduced. Programs of YJK and MIDAS Gen were used to calculate the overall structure under the frequently occurred earthquakes, and the elastic time-history analysis method was used for supplementary check. Performance-based design method was adopted to ensure the performance requirements of main components under fortification and rare earthquakes. Programs of 3D3S and MIDAS Gen were used to analyze the truss structure of the roof, to control structural deformation and stress ratio. The finite element analysis was applied to analyze key nodes. The analysis results show that the design scheme is reasonable and the structure is safe and reliable.
Keywords:Yantai Bajiaowan International Convention and Exhibition Center； long-span steel frame structure； plane truss structure； out-of-code structure； performance-based seismic design； elastic time-history analysis
