［摘要］煙臺八角灣國際會展中心項目中綜合文化活動中心為地下1層，地上5層的鋼框架結(jié)構(gòu)，屋蓋為雙向桁架與單層網(wǎng)殼的多重組合形式。介紹了結(jié)構(gòu)布置、計算參數(shù)、超限情況等，對結(jié)構(gòu)進行了反應(yīng)譜法、彈性時程、抗震性能化設(shè)計和穩(wěn)定性等方面的分析，并對結(jié)構(gòu)進行了罕遇地震作用下的動力彈塑性時程分析以研究結(jié)構(gòu)的抗震性能。同時對旋轉(zhuǎn)樓梯進行了應(yīng)力、撓度、舒適度的驗算，對托柱桁架進行了節(jié)點有限元分析。結(jié)果表明，綜合文化活動中心具有良好的抗震性能，能滿足預(yù)定的性能目標(biāo)。

Abstract: The comprehensive cultural activity center in Yantai Bajiaowan International Convention and Exhibition Center is a steel frame structure with one underground floor and five floors above the ground. The roof is a multiple combinatorial of two-ways plane truss and single-layer latticed shell. The structural layout, calculation parameters and the out-of-code situations were introduced. The elastic response spectrum method, elastic time-history analysis, performance based seismic design and stability analysis of the structure were conducted. The dynamic elastic-plastic time-history analysis was conducted to study the seismic performance of the structure under the rare earthquake. At the same time, the stress, deflection, and comfort of the whirling stairs were checked, and the finite element analysis of the supporting-column truss joints was carried out. The analysis results show that the comprehensive cultural activity center has good seismic performance and can fully meet the requirements of predetermined performance objectives.
Keywords:Yantai Bajiaowan International Convention and Exhibition Center； steel frame structure; long-span structure； plane truss system； multiple combinatorial roof； whirling stairs； seismic performance
