某大跨室内演艺剧场结构设计研究

Structural design of a large-span indoor performing Theatre

本工程为型钢混凝土框架剪力墙支承的大跨超限双层网壳结构。该结构通过对单体网壳和整体建模的包络设计,以及对薄弱部位关键构件的性能设计,保证了大跨网壳及其支承结构在其生命周期内具有良好的可靠性。因此,本文主要介绍该工程的结构设计思路、计算方法和采取的主要措施,并结合建筑造型来控制屋面网壳产生的水平推力对下部支承竖向构件的不利影响。

This project is a large span over-limit double-layer reticulated shell supported by steel reinforced concrete frame shear wall.Through envelope design of single reticulated shell and overall modeling,and performance design of key components in weak parts,the structure ensures good reliability of large-span reticulated shell and its supporting structure in its life cycle. Therefore,this paper mainly introduces the structural design ideas,calculation methods and main measures adopted in the project,and combines the architectural modeling to control the adverse effects of horizontal thrust produced by roof reticulated shells on the vertical members supported at the lower part.
