采用“双机三点吊”吊装钢筋混凝土长柱的最优方案的研究

Study on the Optimum Scheme of “Double Crane and Threehoisting Point”for the Whole Erection of the Large scale Slender R.C.Column

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 restrained rope system“double crane and three hoisting point”for the whole erection of the large scale slender R.C.column is sutdied with respect to optimization of rope confignration,hoisting point and rope element height (corresponding to best rope element length).Using the criterion of “minimum bending strain energy”,the optimum hoisting points of the column are determined with the method of “three step cycling coordinate search”.Optimized resultant are references for engineers and technicians.
