Abstract

Abstract

The roof of Fengyang Gymnasium is a long-span complex assembled steel structure composed of steel trusses, inner ring grids and steel cables, the height of the structure is 24 m, the span is 82.2 m, and the projected area is about 11 851 m². According to the characteristics of the project, the three-dimensional computational model of the steel roof was established by means of large analysis software. Firstly, the integral lifting construction scheme was described, the selection of lifting points and main construction steps were determined. Secondly, through the mechanical analysis at each stage of construction, the comparisons between the forming at construction stage and the once-forming, the analysis of the influence of temperature change and elevation deviation of lifting point on the structure, the safety of the construction process and the rationality of the structure forming were verified, the design and mechanical analysis of lifting lug and lifting bracket in auxiliary structure were carried out. Finally, by means of safety monitoring, the reliability of the mechanical analysis was verified, and the basic guarantee for the safe construction of the steel roof structure was provided.
