重庆万州文化艺术中心二期结构设计

Structural design of Chongqing Wanzhou Culture and Art Center Phase Ⅱ

本工程主体部分采用钢筋混凝土框架-剪力墙结构体系;音乐厅屋顶采用钢桁架体系;排练厅及入口采用落地钢结构单层网壳体系。结构存在扭转位移比超限、楼板开大洞、局部多塔等不规则项。通过计算分析,验证了当上部钢结构跨度大、重量轻、刚度较弱时,主体结构与上部钢结构之间相互间影响较小,独立模型与合模模型均为合理结构受力状态。

The main part of the project are made of reinforced concrete frame-shear wall structure system;the roof of the concert hall adopts a steel truss system;rehearsal hall and entrance adopt floor-to-ceiling steel single-layer reticulated shell system.There are irregular items such as torsion irregularity,open holes,and multi-tower irregularity for the building.By computational analysis,verified that when the upper steel structure has a large span,light weight,and weak stiffness,the main structure and the upper steel structure have little influence on each other,both the independent model and the combined model are in a reasonable structural stress state.
