                                  [摘要]基于2022年卡塔爾世界杯主場館盧賽爾體育場項目,介紹其主體結構的構成和外部尺寸,重點分析屋面結構、主體鋼結構的組成和整體受力原理。確定體育場屋面索網的總體構成和主要幾何參數,研究屋面主索網結構、次索網結構中各構件的作用和相互關系。對索網結構的零狀態、初始態以及荷載態進行定義,總結形態分析的目的、意義和難點。利用ANSYS3D3S進行膜結構安裝前后的形態分析,分析膜安裝前后的整體結構位移、主索豎向位移、主體鋼結構的徑向與環向位移,并計算和比較屋面索網各主要構件的內力。研究表明,魚尾式索網屋面安全可靠、造型輕盈、受力性能優異,是大型體育場館屋面結構的理想選擇;在形態分析方面,以膜安裝前后進行初始態分析可為之后的荷載態分析奠定良好基礎。

                                  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.
