［摘要］2019北京世園會生活體驗(yàn)館地上采用鋼框架結(jié)構(gòu)體系，基礎(chǔ)形式為筏板基礎(chǔ)及獨(dú)立柱基。兩種不同基礎(chǔ)形式間有較大的沉降差，故采用CFG樁復(fù)合地基。對上部結(jié)構(gòu)中樓板大開洞及不連續(xù)處進(jìn)行樓板應(yīng)力分析，采取相應(yīng)加強(qiáng)措施處理。因施工難度大，將雙向曲線屋面由現(xiàn)澆樓板改為鋼筋桁架樓承板，進(jìn)行樓板應(yīng)力分析并提供相應(yīng)節(jié)點(diǎn)細(xì)節(jié)設(shè)計(jì),以保證施工及使用階段安全。

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.
Keywords:International Horticultural Exhibition 2019, Beijing, China； Living Experience Pavilion;
