[摘要]基于2022年卡塔尔世界杯主场馆卢赛尔体育场项目,介绍其主体结构的构成和外部尺寸,重点分析屋面结构、主体钢结构的组成和整体受力原理。确定体育场屋面索网的总体构成和主要几何参数,研究屋面主索网结构、次索网结构中各构件的作用和相互关系。对索网结构的零状态、初始态以及荷载态进行定义,总结形态分析的目的、意义和难点。利用ANSYS3D3S进行膜结构安装前后的形态分析,分析膜安装前后的整体结构位移、主索竖向位移、主体钢结构的径向与环向位移,并计算和比较屋面索网各主要构件的内力。研究表明,鱼尾式索网屋面安全可靠、造型轻盈、受力性能优异,是大型体育场馆屋面结构的理想选择;在形态分析方面,以膜安装前后进行初始态分析可为之后的荷载态分析奠定良好基础。

Abstract: Based on the Lusail Stadium, the main stadium for Qatar World Cup in 2022, this article introduces the composition and external dimensions of the main structure, focusing on the analysis of the roof structure, the main steel structure and the overall force principle. The overall composition and main geometric parameters of the stadium roof cable net are determined, and the role and relationship of each component in the main and secondary cable net structures of the roof are researched. The zero state, initial state and load state of the cable net structure is defined, and the purpose, significance and difficulty of the morphological analysis are summarized. Before and after the installation of the membrane structure, morphological analysis is done using ANSYS and 3D3S. The overall structural displacement, vertical displacement of the main cable and the radial and circumferential displacement of the main steel structure are analyzed, and the internal forces of the main components of the roof cable net structure are calculated and compared. Studies have shown that fishtail cable net roofs are safe and reliable, light in shape, and excellent in stress performance. They are ideal choices for large stadium roof structures. In terms of morphological analysis, it is scientific to analyze the initial state before and after membrane installation, which can be used as load state analysis lays a good foundation.
