Abstract: The daylighting roof of the commercial podium of Xuzhou Central International Plaza is a large-span steel structure with complicated supporting conditions. The daylighting roof and the commercial podium as a whole are complicated super high rise hybrid structure of steel and concrete. Aimed at the steel structure of the daylighting roof, the process and method of the structure layout, the seismic analysis and the ultimate bearing capacity analysis of overall stability were introduced. Some key issues were introduced, including progressive collapse resistance analysis under three kinds of modes and the nonlinear analysis of the complex cast steel joints. The analysis and solutions were provided.
Keywords: large-span steel structure; resisting progressive collapse; complicated cast steel joint
