Analysis of the Structural Design of Haicang Sports Center in Xiamen
The Haicang Sports Center Stadium in Xiamen has a concrete frame structure for its upper stands,and the stadium canopy adopts a large-span cantilever structure with inverted triangular spatial pipe trusses.Considering the characteristic of the long stands structure,we analyzed the temperature effects using Midas Gen software and studied the distribution patterns of displacement and temperature stress under heating and cooling conditions.Based on the calculation results,we implemented reinforcement measures at locations where the stress excee-ded the tensile strength design value of the concrete.Additionally,to verify the accuracy and reliability of the wind resistance design,we conducted wind tunnel numerical simulations and experiments in areas with high wind pressure,comparing the results of both.During the re-search,we also proposed an integrated mechanical connection support node scheme to address the problem of excessive tension in the main support of the large-span canopy truss,solving the issues of high uplift force and connection at the support node.These research findings provide important basis for wind resistance design of steel structure canopies.
