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