四川复杂剧院建筑的结构设计

Structure design of a complex theatre building in Sichuan

主要介绍了四川某复杂剧院建筑的结构设计思路、结构设计方案的优化和确定,并采用两种不同的计算模型进行整体计算,对比计算结果,以验证计算模型的可靠性。对特别不规则的结构,补充了弹性时程分析。之后,基于设计过程中的重要部位和关键问题,介绍了大跨度桁架支座节点连接,台口转换构件,二层悬挑楼座的结构设计以及基础设计等,为类似工程设计提供参考。

The article is mainly about the train of structure design,optimization and confirmation of structural scheme for a theater building in Sichuan province.Two calculation models based on different mechanical methods are built to calculate the overall indexes.Through comparison of these overall results,reliability of the calculation models can be verified.Besides,elastic time history analysis is also carried out for particularly irregular structure.Then some important parts or key problems are shown to provide references for similar projects in future,such as the support joint of long-span truss structure,transfer structure over proscenium arch,structure of the cantilevered circle on the second floor,foundation design,etc..
