［摘要］武林美术馆建筑外形独特，其下部5层为钢框架-混凝土筒体结构，顶部3层为钢桁架-混凝土筒体结构。结构存在平面不规则、楼板不连续和竖向不规则等多项不规则，是一种较为新型的大跨空间结构体系。从结构抗震性能化设计、楼板应力分析、抗连续倒塌性能、楼板舒适度和关键节点分析这五个方面阐述了本工程的设计思路和分析过程。对于分析过程中的技术难点，提出了相应的解决方案。结果表明，该结构安全合理，抗震性能良好。

Abstract: Architectural appearance of Wulin Art Museum is special. The five-story building on bottom is steel frame-concrete tube structure, and the three-story building on top is steel truss-concrete tube structure. Several irregularities such as plane irregularity, floor discontinuity, vertical irregularity and so on exist, the building is a relatively new type of large-span spatial structure system. The design concept and the analysis process of the project was introduced from five aspects: the performance-based seismic design, floor stress analysis, anti-continuous collapse performance, the vibration comfort of floor and the analysis of key joint. For the technical difficulties in the analysis process, corresponding solutions were proposed. The results show that the structure is safe and reasonable,  seismic performance is good.
