Abstract:Suzhou Modern Media Plaza is a typical urban complex building with diverse functions and unique landmark shape. In the structural design of this project, a variety of new steel structure technologies were adopted. The research, analysis and design application of related technologies were summarized. The project team put forward a new type of steel truss-steel plate wall with opening structure system for the large-span and heavy-load structure with 40m span, and through theoretical analysis and test, its mechanical properties were systematically studied, and the corresponding design methods were introduced; for M-shaped lighting roof set on four monolithic buildings, seismic isolation support and prestressed tie rod combination steel structural system were adopted, which solved the problem of complicated mechanism and differential deformation of the connected body; for roof steel structure with a span of 40m and a height difference of 50m, a catenary flexible structural system was adopted based on the principle of strain energy optimization; for 25m large-span steel staircase, the cross tension string prestressing structural system was adopted to complete the design. The steady state analysis method was used to calculate the comfortableness of the pedestrian.
Keywords:steel truss-steel plate wall with opening structure; tensioned spatial steel structure; strain energy optimization; cross tension string; steady state analysis method
