杭州上城区体育中心由于用地及功能等限制,采用一体多馆建筑形式,主体结构采用框架-剪力墙结构体系,大跨度楼层采用钢骨柱-钢桁架承重体系,部分钢骨柱间设置中心钢支撑。进行结构分析时,根据工程特点确定结构的性能设计目标,采用YJK,SATWE,MIDAS Building等软件进行对比分析,针对扭转不规则、楼板不连续、竖向构件侧向刚度和受剪承载力突变、单跨穿层柱等超限情况,对结构采取相应的加强措施,以实现整体结构的抗震性能。此外,采用简化计算法与SAP2000有限元分析法对大跨楼盖的振动舒适度进行了核算。
Due to the limited land use and function, Hangzhou Shangcheng District Sports Center adopts the integrated multi-pavilion building form. The main structure adopts the frame-shear wall structure system. The long-span floor adopts the steel bar-steel truss bearing system and the center between some steel columns Steel support. In structural analysis, the structural performance design goals were determined according to the engineering characteristics. The software YJK, SATWE and MIDAS Building were used for comparative analysis. In view of the irregular torsion, the discontinuity of floor slab, the lateral stiffness and the sudden change of shear strength of vertical members, Single span through the pillars and other overrun situation, the structure to take the appropriate measures to strengthen the overall structure of the seismic performance. In addition, the simplified calculation method and SAP2000 finite element analysis method were used to calculate the vibration comfort of long-span floor cover.
