摘要:苏州360剧场室外人行钢连桥采用钢箱梁上覆现浇混凝土板,北侧上承挂板龙骨体系。采用MIDAS Gen等软件,进行静力弹性计算及时程分析,发现了大跨度钢连桥主体结构采用钢箱梁可以满足承载力和变形要求;通过多种支座连接方式的对比分析,验证了室外人行钢连桥采用一端固定、一端单向活动球型支座的合理性;介绍了室外钢连桥舒适度控制要素和计算方法等;提出了支承桥墩的抗震性能目标要求;同时分享了支座节点设计、球型支座选用及挂板龙骨与主体钢箱梁一体化设计等研究成果。

Abstract: The outdoor steel pedestrian bridge of Suzhou 360 theater adopts a steel box-section beam which a concrete slab is laid on, and a hanging slab skeleton system is supported on the north side. Using software such as MIDAS Gen to carry out elastic static calculation and elastic time-history analysis, it is found that the steel box-section beam can meet the bearing capacity and deformation requirements when the main structure adopts long-span steel pedestrian bridge. Through the comparative analysis of various bearing connection methods, the rationality of the outdoor steel pedestrian bridge with a hinged support and a one-way moving spherical support was verified. The comfort control elements and calculation methods of outdoor steel pedestrian bridge were introduced. The seismic performance target requirements of the supporting pier were put forward. At the same time, the research results of the support joint design, the selection of the spherical support and the integration design of the hanging slab skeleton and the main steel box-section beam were shared.
Keywords: Suzhou 360 Theater; steel pedestrian bridge; steel box-section beam; vertical comfort; spherical support
