摘要
针对我国现行GB50017-2002《钢结构设计规范》中规定的对承受动力荷载重复作用的钢结构构件及其连接进行疲劳设计的要求,采用罚函数方法SUMT(SequentialUnconstrainedMinimizationTechnique)选择构件截面积最小的目标函数对钢结构进行优化设计,并且结合大型工具软件MATLAB编写了在满足强度、疲劳寿命等条件下的优化程序进行构件截面积最小设计的实例计算.
According to the GB 50017-2002 design code of steel structure, the component and joint of steel structure must be considered as fatigue objects when they are acted by periodic loads. Thus fatigue problem besides intensity problem must be considered. The optimization algorithm of SUMT tooptimize the fatigue design of steel structure for the minimal area of cross section is applied. As an illustrative instance, calculating codes with MATLAB language to deal with it is presented.
