摘要
锦州滨海体育中心体育场采用混合结构体系,质量和刚度分布不均,应重点考虑结构存在的超长、超限问题,以确保安全。看台适当设置防震缝(兼伸缩缝)是解决结构规则性和超长问题的有效方法;对于结构超限,应采用抗震性能化设计方法对超限构件按设定的性能目标进行设计;看台与钢罩篷、落地拱与基础支座之间连接复杂,采用包络设计的方法可以确保计算内容涵盖结构最不利的受力工况;对于钢罩篷复杂节点,应进行精确的研究分析,必要时宜使用铸钢节点和成品支座。
With mixed structural system, the stadium of Jinzhou Coastal Sports Center has distribution of mass and stiffness unevenly. Out-of-codes problems should be focused on to ensure the safety of the structure. The set of seismic joint （or expansion joint） on the stand is an effective method to solve the out-of-codes problems. Performance based seismic design method is applied to unqualified members according to the established performance goals. The connection between the stand and steel canopy is complex, so is the connection between landing arches and foundation bearing. Envelope design method is applied to cover the most unfavorable bearing conditions of the structure. Accurate computational analysis should be carried out for the complex node of the steel canopy, in which cast steel nodes and finished bearing could be used if necessary.
