北京奥运会国家体育场威亚主钢索是奥运会及残奥会开闭幕式上空表演系统的承载基础。采用有限元分析程序ANSYS,对国家体育场上空10根钢索在8种工况下的变形和受力进行了计算分析,并与理论解进行了比较。结果表明,数值计算结果与理论解基本一致,计算结果可靠。为同类索网结构的变形和受力分析提供参考。
Beijing Olympic Games National Stadium Weiya main cable is the bearing foundation of the opening and closing ceremonies over the opening and closing ceremonies of the Olympic Games and Paralympics. The finite element analysis program ANSYS was used to calculate and analyze the deformation and stress of 10 steel cables over the national stadium under 8 working conditions, and compared with the theoretical solution. The results show that the numerical results are basically consistent with the theoretical solutions and the calculation results are reliable. Provide reference for deformation and force analysis of similar cable network structures.
