| 摘 要： | 保定长城体育馆看台为钢框架结构,屋面采用正放三角形钢管桁架结构,弦杆和腹杆均为无缝钢管。采用ANSYS软件,对结构在各主要荷载组合工况下的结构受力进行了分析,结果表明,结构受力合理,构件强度满足要求。分析了结构的整体稳定性和动力特性,计算结果表明,恒载和最不利活荷载组合为结构的最不利工况,结构在此工况下的强度和整体稳定性均满足要求。

| Abstract: | The steel frame structure is adopted in the grandstand of Baoding Changcheng gymnasium and the triangle steel tube truss structure is used in the roof.The chord and web members are all seamless steel tube.The ANSYS software is used to analyze the structure bearing capcity under main load combinations.The results show that the structure internal force is rational and the member strength meets the requirement.The structure integer stability and dynamic behavior are analyzed.The calculation results show that the combination of dead load and the most disadvantage live distribution is the most disadvantage load condition,and the structure strength and integer stability meet the requirement. |
