摘要
Abstract
The steel roof of the Chibi Sports Center Gymnasium is a large-span spatial structure.Its planar projection is elliptical,with a span of 137.8 m×97.6 m,and it is supported by inner and outer rings of steel-reinforced concrete columns.According to the column positions,the steel roof is divided into inner and outer fields.The steel roof of the inner field adopts a suspen-dome structure with an irregular elliptical plan projection and a span of 80.7 m×67.2 m.The steel roof of the outer field adopts a single-layer latticed shell structure,and a beam-string structure is used in the local large-span region,with a maximum span of 33.8 m.To ensure the rationality of the structural design of the steel roof,the Midas Gen software was used to conduct member stress analysis,modal analysis,temperature effect analysis,buckling analysis,deformation analysis and construction simulation analysis on the steel roof.The calculation results show that all structural indicators of the steel roof meet code requirements.This paper also elaborately introduces the selection and analysis of prestressed cables,the adjustment process of calculation model,and the key joint configurations.The design methods and measures adopted in this project can serve as a reference for similar engineering projects.关键词
