( Guangxi Hualan Design&Consulting Group, Nanning 530011, China)Abstract: Fangchenggang Culture&Art Center is a building that has a large span roof with complex bionic shape, which brings challenge for structural design. With an irregular scallop-shaped plan, this building is 125m long and 115m wide. The main structural system is concrete frame with shear walls, while the steel roofis a latticed shell structure. Key issues in structural design such as modeling of the complicated roof, wind-resistant and seismic design, selection of foundation, and anti-corrosion design were discussed. This project can be a good reference for the design of similar buildings.
Keywords: large span space structure; latticed shell; buckling analysis; wind-resistant design; time history analysis; anti-corrosion
