［摘要］2019北京世园会生活体验馆地上采用钢框架结构体系，基础形式为筏板基础及独立柱基。两种不同基础形式间有较大的沉降差，故采用CFG桩复合地基。对上部结构中楼板大开洞及不连续处进行楼板应力分析，采取相应加强措施处理。因施工难度大，将双向曲线屋面由现浇楼板改为钢筋桁架楼承板，进行楼板应力分析并提供相应节点细节设计,以保证施工及使用阶段安全。

Abstract:Steel frame structural system was adopted on the ground of Living Experience Pavilion of International Horticultural Exhibition 2019, Beijing, China. The foundation forms were raft foundation and independent column foundation. CFG pile composite foundation was adopted because of the large settlement difference between the two kinds of foundations. Stress analysis was conducted on floors with large openings and discontinuities in the upper structure, and corresponding reinforcement measures were taken to deal with them. Because of the difficulty of construction, the hyperbolic roof was changed from cast-in-situ floor to reinforced truss floor slab, and the floor stress analysis was carried out, and the detailed design of the corresponding joints was provided to ensure the safety of construction and use stages.
