［摘要］某多层钢结构展览馆由于建筑外形和功能要求，北区采用中心支撑-钢框架结构体系，结构存在多项不规则情况。采用了性能化设计方案，对于结构内庭侧，利用幕墙龙骨形成的空间网格结构作为竖向传力构件，并对其进行稳定性全过程分析，计算结果表明结构稳定性满足要求；对结构进行罕遇地震作用下静力弹塑性分析，发现结构自身具有较好的抗震性能；主要节点多尺度分析表明，节点在大震下基本处于弹性工作状态。

Abstract: Due to the architectural appearance and functional requirements of a multi-story steel structure exhibition hall, the centrally braced steel frame structural system is adopted in the north area of the exhibition hall, and there are many irregularities in the structure. The performance-based seismic design scheme was adopted. For the inner side of the structure, the space grid structure formed by the curtain wall keel was used as the vertical force transmission component, and the whole process of its stability was analyzed, the calculation results show that the structure stablity meets the requirements. After static elastoplastic analysis of the structure under the rare earthquake, it is found that the structure has good seismic performance. The multi-scale analysis of the main joints shows that the joints are basically in elastic working state under rare earthquake. 

Keywords:performance-based seismic design； whole process stability analysis； multi-scale analysis； static elastoplastic analysis； temperature stress analysis
