Application of Folded Plate Structure with Flat Truss in Long-Span Steel Roof Structure

Folded plate structure with flat truss is applied in the roof steel structure of the natatorium in Huai’an sports center. In this paper, mechanical analysis on loading case and dynamic characteristics of the roof steel structure is accomplished. Overall stability analysis is also completed by FEM software STRAND7. Analysis results indicate the scheme is in accordance with safety and aesthetic is appropriately designed, which could figure out that bearing capacity and seismic performance of the folded plate structure are satisfactory.
