摘要:杭州亚运会曲棍球场钢罩棚结构平面形状为椭圆形。屋面结构体系为钢桁架拱结构:由南北向2榀三管钢桁架拱和最外侧2根圆钢管拱组成主受力结构,东西向通过单向平面桁架连接,组成次受力结构。钢结构屋面通过8个支点落于4个高约6m的混凝土高支墩基座上,高支墩采用桩基础。介绍了曲棍球场看台屋面钢结构的方案比选和风荷载受力特点;进行了多支座类型的整体计算,并取包络值;考虑了复杂节点的应力分析。介绍了大弯矩、大剪力等复杂受力的高支墩及基础设计方法;提出了考虑桩水平承载力、增加结构自重、增设拉梁等综合措施解决基底大水平推力问题。分析结果表明:曲棍球场的各项性能指标均能满足设计要求。

Abstract: The steel canopy shape of hockey stadium for Asian Games Hangzhou is an ellipse. The structural system of the roof is steel truss arch structure: the main load-bearing structure along the direction of south-north consists two three-tube steel trusses arches and two round steel pipe arches, and the secondary load-bearing structure uses single truss to connect to main truss from east to west. The steel structure roof is constructed at four 6-meter-high concrete high-piers through eight pivot points, and the high-pier adopts pile foundation. Scheme comparison of the steel roof and wind load analysis of the structure was introduced. The overall calculation for multiple support types and envelope value was also included. Stress analysis of complex nodes was performed. Foundation design method for large bending moment and large shear force of the high pier was introduced. The comprehensive measures such as considering the horizontal bearing capacity of pile, increasing structural self-weight and the tie beam were put forward to solve the large shear force in the basement. The results of analysis show that all indicators of hockey stadium can meet requirements of design.
