摘　　要：杭州电竞中心内圈主体结构采用钢框架-支撑结构,外圈采用“大倾角梭形斜柱+多段钢折梁框架”,是集承重与抗侧力于一体的结构体系,屋盖采用车辐式索承网格自平衡结构形式。详细介绍了地下结构、中央场馆结构的设计要点,门厅处利用建筑造型空间设计为多段钢折梁与跨层桁架相结合的结构形式;室内二层至三层楼面设计一浮空弧形人行桥,截面形式为薄壁钢箱梁,桥宽2.2m,跨度57m,采用“上挂下支”的稳定结构形式。对整体结构进行了静力弹性、动力弹塑性、振动台试验、典型节点有限元、整体稳定以及局部稳定等系列分析与试验。结果表明:结构在静力荷载和地震作用下强度和刚度均满足规范要求;典型节点极限承载力为荷载设计值的4.17倍;结构整体稳定性安全系数为3.79;斜柱局部稳定安全系数为2.52。合理的设计保证了结构的安全、经济和实用性。The main structure of the inner ring of Hangzhou E-sports Center adopts the steel frame-support structure,and the outer ring adopts the structural system of large inclination angle fusiform inclined column+multi-section steel folding beam frame,which integrates load-bearing and lateral force resistance.The roof adopts the self-balanced structure of spoke-type cable-supported grid.The design points of underground structure and central venue structure were introduced in detail.The structural form of multi-section steel folding beam and cross-layer truss is designed by using architectural modeling space at the entrance hall.A floating curved footbridge is designed on the second to third floors of the building.The cross-section is a thin-walled steel box girder with a width of 2.2m and a span of 57m.The bridge adopts a stable structure of hanging up and supporting down.A series of analyses and tests such as static elasticity,dynamic elastoplasticity,shaking table test,typical joint finite element,overall stability and local stability were carried out on the whole structure.The results show that the strength and stiffness of the structure meet the requirements of the code under static load and earthquake.The ultimate bearing capacity of typical joints is 4.17 times of the load design value.The safety factor of the overall stability of the structure is 3.79.The local stability safety factor of inclined column is 2.52.The reasonable design ensures the safety,economy and practicability of the structure.
