摘　　要：杭州国际博览中心长约432m,宽约264m,规模大、功能多,结构体系较复杂。工程主体部分采用钢管混凝土柱与大跨钢桁架组成的框架结构,屋顶花园钢结构采用曲面钢网壳和单层球壳,附属办公楼采用现浇混凝土框架-剪力墙结构。介绍了初步设计中的一些关键性问题及相应的技术措施,包括荷载取值、结构分析与选型、超限情况及抗震性能化设计、结构超长论证分析等,该工程目前已经通过超限审查。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.
