摘要

为了能简易地算出输电塔的抗侧刚度,采用Matlab软件编制一个通用程序,对单层输电塔进行静力分析,得出某一给定水平力下的位移,以SJD-90°终端转角塔为例得出单层抗侧刚度,进而可得出整个输电塔每一层抗侧刚度,最后根据刚度串联理论估算了整塔抗侧刚度为7.16×106 N/m。试验验证结果表明,该方法算出的输电塔抗侧刚度较试验结果相差17%,可满足工程实际要求。
In order to simply calculate the lateral stiffness of transmission tower,general purpose program based Matlab software is developed to analyze static force of single layer transmission tower.The displacement is obtained under the given horizontal force.Taking SJD-90°terminal corner tower for an example,the lateral stiffness of single layer is obtained and then the lateral stiffness of each layer in transmission tower is determined.Based on the theory of stiffness series connection,the estimated lateral stiffness of the whole tower is 7.16×106N/m.Test results show that the error between the proposed method and experimental data is 17%,which meets the engineering requirement.
