海花岛歌剧院结构设计

Structure design of Ocean Flower Island Opera House

歌剧院由于观演的要求,具有体量大、跨度大、楼板开洞多、错层多、建筑功能复杂等特点,因此歌剧院结构设计难度非常大。以海花岛歌剧院设计为例,介绍了项目的基础设计、抗震超限情况、抗震措施,并进行了弹性分析、弹性时程分析、楼板应力分析和罕遇地震作用下静力弹塑性分析等计算,结果表明结构满足规范要求。

The opera house has the characteristics of large size,large span,floor openings,staggered,building complex function etc. So the structure design of an opera house is very difficult. Take the design of the actual Ocean Flower Island Opera House as an example,the foundation design,out-of-code characteristics and corresponding seismic measures were introduced. The elastic analysis,elastic time history analysis,floor stress analysis and static elastoplastic analysis under rare earthquake analysis were carried out. The results show that the structure meets the code requirements.
