本文介绍一种解塔机双吊点水平臂内力简捷方法。其要点是将臂和拉杆视为由受弯构件和轴力构件组成的混合结构，结构的位移由臂的弯曲变形及拉杆的轴向变形共同产生，弹性支承的柔度系数由拉杆参数求得，同时选取合适的静定基本体系，即可简捷地求出结构内力。
This article describes a solution tower crane double point horizontal arm internal force simple method. The main point is that the arm and the tie rod are regarded as a hybrid structure composed of a flexural member and an axial force member. The displacement of the structure is jointly generated by the bending deformation of the arm and the axial deformation of the tie rod. The flexibility coefficient of the elastic support is obtained from the parameters of the tie rod , At the same time select the appropriate static basic system, you can simply calculate the structure of internal forces.
