［摘要］烟台八角湾国际会展中心项目中综合文化活动中心为地下1层，地上5层的钢框架结构，屋盖为双向桁架与单层网壳的多重组合形式。介绍了结构布置、计算参数、超限情况等，对结构进行了反应谱法、弹性时程、抗震性能化设计和稳定性等方面的分析，并对结构进行了罕遇地震作用下的动力弹塑性时程分析以研究结构的抗震性能。同时对旋转楼梯进行了应力、挠度、舒适度的验算，对托柱桁架进行了节点有限元分析。结果表明，综合文化活动中心具有良好的抗震性能，能满足预定的性能目标。

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
