主要研究均载钢筋混凝土长柱“双机三点吊”约束绳系的最优绳程组合、最优绳元高度 (对应最优绳长 )、最优吊点坐标。以“弯曲应变能最小”为优化准则、采用“三步循环坐标搜索法”求解最优吊点坐标。优化结果可供工程吊装技术人员使用参考。
The main research includes the optimal rope combination of reinforced concrete long column “double machine three-point suspension” restraint system, the optimal rope element height (corresponding to the optimal rope length) and the optimal lifting point coordinates. Taking “the minimum bending strain energy” as the optimization criterion, the “three-step cycle coordinate search method” is used to solve the optimal lifting point coordinates. Optimization results for engineering hoisting technical staff to use for reference.
