安阳文体中心体育场结构设计

Structural design of Anyang Sports Center Stadium

安阳文体中心体育场为4万座乙级体育场,采用混凝土框架看台、悬挑桁架罩棚。结合相关规范要求,从结构体系、概念设计、抗震性能设计等方面对复杂结构设计相关问题进行着重论述,采用多种结构有限元计算软件对屋盖和整体进行弹性、弹塑性分析,对屋盖的分叉柱支座铸钢节点进行了有限元分析,对超长混凝土看台进行了合理处理、释放温度应力。计算表明,通过合理地布置结构体系,采取适当的构造措施,可实现建筑形态和功能、满足结构的抗震性能要求。

Anyang Sports Center Stadium is a 40000-seat Grade-B stadium, with concrete frame stands and cantilevered truss canopies. Combining with the requirements of relevant codes, the problems related to complex structural design were analyzed from the aspects of structural system, conceptual design, and seismic performance design. Various structural finite element calculation programs were used to carry out elastic and elasto-plastic analysis of the roof and the whole structure. The finite element analysis was carried out on the cast steel joints of the bifurcated column supports, and the super-long concrete stands were reasonably treated to release the temperature stress. Calculations show that by rationally arranging the structural system and taking appropriate structural measures, the architectural form and function can be realized and the seismic performance requirements of the structure can be met.
