摘要
武汉商学院游泳馆的建筑造型较为独特,结构存在抗震不规则。对大跨度大空间的游泳馆结构进行了抗震性能化分析,设定了抗震性能化目标,采用时程分析法计算并分析了小震和罕遇地震下结构的抗震性能。对屋面开有较大洞口的大跨度体育场馆,屋面结构布置提出新的布局和思路,将洞口三边设置成框架结构与屋面钢结构网架结合形成完整大洞口,并介绍了相关结构布置方法,可为类似建筑造型的结构布置方法提供借鉴。对下垂弧型屋面结构的结构布置进行了分析,为减小弧梁对整体结构刚度影响,提出了三点铰接的结构布置方案和相关节点构造。基础设计结合基坑开挖布置,游泳馆内部整体筏板基础的降板处结构布置与泳池基坑开挖边坡结合,节省了工程的工期和投资。
The Wuhan business University nataorium is a special architectural shape,and its building configuration is irregular.Performance-based seismic analysis was carried out on the structure with large span and large space,the performance-based seismic objective was set,and the seismic performance of the structure under small and rare earthquakes was calculated and analyzed by using time-history analysis method.This paper puts forward a new thought for the roof structure layout of the large span gymnasiums with large holes in the roof,in which the three sides of the entrance are set up as a frame structure combined with the steel space grid structure to form a complete large hole,and introduces the relevant structure layout method,which can provide reference for the structure layout of similar building shape.The structure layout of the drooping arc roof structure is analyzed,and the three-point hinged structure layout scheme and the related joint structure are put forward in order to reduce the influence of arc beam on the stiffness of the whole structure.The foundation design is combined with the layout of retaining and protection for excavation,and the overall structure layout of the raft foundation in the swimming pool is combined with the slope of the foundation pit,saving time and cost.
