Abstract:Hangzhou International Expo Center,which is about 432m long and 264m wide, is a large-scale, multifunctional and complicated structure. The main body of the project adopts the frame structure combined by concrete-filled steel tubular column and long-span steel truss. Meanwhile, the roof garden is composed of the curved steel structure and single-layer spherical lattice shell, in addition the subsidiary office building is made of the frame-shear wall structure. The key problems and relevant technical measures in the preliminary design are introduced, including loads calculation,structural analysis and forms, the out-of-code problems, the performance-based seismic design and analysis of the super-length structure etc. Up to now, the project has already passed the out-of-code evaluation.
Keywords:concrete-filled steel tubular column; long-span steel truss; frame-shear wall; single-layer spherical lattice shell; roof garden; super-long structure; out-of-code evaluation
