摘要
主要介绍了狮山艺术剧院的结构布置、超限判别、主体结构分析及设计等内容。大剧场观众厅周边扭曲的弧形倾斜混凝土墙体采用斜柱+斜撑的方式进行模拟,确保模型分析更为精准高效,受力更为清晰合理。大剧场根据规范采用三水准设防、两阶段设计方法,并采用基于性能的抗震设计方法,弹性分析和弹塑性分析表明,主体结构能够满足规范规定的各项指标和既定的性能目标。钢结构顶棚动力特性分析和竖向地震作用分析表明,钢结构顶棚结构地震反应较小,不起控制作用。
This paper mainly presents the structural layout, overrun discriminant, structure analysis and design of the Suzhou Shishan Art Theater. The twisted arc-shaped inclined concrete walls surrounding the auditorium are simulated by the inclined columns plus diagonal braces to ensure that the model analysis is more accurate and efficient, and the force analysis is more clear and reasonable. The three-level fortification and two-stage design methods are adopted, and performance-based seismic design methods are also used. Elastic analysis and elastoplastic analysis show that the structure can meet the specifications and scheduled performance object. The analysis of the dynamic characteristics and the vertical seismic action of the steel structure roof show that the structure has a small seismic response which does not have a controlling effect.
