摘要
结合实际工程设计 ,选取轻型薄壁钢管拱形屋面的矢高、拱形桁架高度、杆件截面面积作为优化设计变量 ,以轻型钢管拱形屋面的总造价最低为目标函数 ,建立了优化设计的数学模型 ,采用直接搜索法与准则法结合的综合优化设计方法 ,按规程要求对轻型钢管拱形屋面的几何外形及杆件的截面进行了综合优化设计 ,考虑了各种情况的荷载作用 ,编制了SLAOP软件 .
In this paper, combined actual project design of the light steel tube truss, the arch rise and height of the arch truss, as well as the cross sections of the steel tubes are taken as the design variables. The total cost of the arch truss roof is taken as the objective function. According to the Code, the mathematical model is established that the combination of the direct searching and criteria methods is adopted as the comprehensive optimum method. The variety loads about the truss structure are considered and the 'SLAOP' is programmed for the optimum design of the truss structure.
