摘要
提出了输电铁塔应用刚度分解法的分析过程,利用刚度分解法分别建立了铁塔各段等效抗弯刚度 矩阵和等效抗剪刚度矩阵代替空间桁架分析法中的总刚度矩阵,求得各段铁塔杆件受力.采用迭代方法求得全 塔结构受力,使计算过程简化.实例计算结果与计算机计算结果吻合很好,可为输电铁塔结构设计提供参考.
An analysis method for transmission tower with the split rigidity method is proposed, with each section of equivalent flexural rigidity matrix and equivalent shear rigidity matrix being established separately by using the split rigidity method to replace the total rigidity matrix in the space truss analysis method, to obtain the internal force of each section of tower. Using an iterative method, the truss member force of entire tower is obtained. The calculating results agree well with the calculating data by using computer.
