青岛体育中心游泳跳水馆网架结构施工监测与模拟分析

Simulation Analysis and Construction Monitoring of Grid Structure for Swimming and Diving Hall in Qingdao Sports Center

鉴于青岛体育中心游泳跳水馆网架结构为复杂大跨多曲面异形钢屋盖结构,施工难度大,施工不易控制,利用弦式应变计和静力水准仪对该网架采用无线监测,监测该网架的竖向位移、支座位移和杆件内力。同时对该网架结构进行了详细的有限元数值分析。研究结果表明,卸载时监测结果和有限元分析结果吻合较好,表明青岛体育中心游泳跳水馆网架结构卸载成功。

In view of complex grid structure for big-bay steel roof structure of Qingdao Sports Center Swimming and Diving Hall,construction is very difficult and not easy to control.The grid structure is monitored wirelessly by using chordal strain gauge and static level meter,the vertical displacement of the grid structure,the displacement and internal forces of bearing are measured.At the same time,the finite element analysis for the grid structure is done in detail.The results show that the results of monitoring are in good agreement with the results of finite element analysis in the unloading time,show that grid structure of Qingdao Sports Center Swimming and Diving Hall is unloaded successfully.
