为了研究大跨度异形建筑构件的支撑系统在设计和施工过程中的安全性,实验针对成都市大魔方演艺中心建筑工程钢支撑系统进行了建模仿真和数值分析.将其支撑系统中具有代表性的一跨分离出来,建立了有效的简化实验模型,并进一步提出了“阶梯式”支撑系统结构.研究基于有限元分析软件Midas Gen,分析了该模型的承载能力和稳定性,有效的验证了此类支撑的安全性.通过分析其结构特性,研究其失效机理,为此类支架的安全设计、施工以及研究提供有利建议和参考.
In order to study the safety during the design and construction of the support system of long-span shaped building components, experiments were carried out on the modeling and numerical analysis of the steel support system for the construction project of Chengdu Grand Magic Square Performing Arts Center. , An effective simplified experimental model is established and the structure of the “ladder-like” support system is further proposed.According to the finite element analysis software Midas Gen, this paper analyzes the bearing capacity and stability of the model and is valid The safety of such supports is verified, the failure mechanism is studied by analyzing the structural characteristics of the supports, and the safety design, construction and research of such supports are provided with favorable suggestions and references.
