【 摘 要 】
An experiment of the full-scale transmission tower is carried out to study the deformation of the tower under unbalanced tension. By adding extra load on the transmission wire connected to the tower and using distributed angle sensors to record the continuous changes of deformation, the deformation rule of the full-scale tower under the unbalanced tension is studied. The experimental results show transmission tower has some complicate performances as a kind of statically indeterminate structure under unbalanced tension as it will incline, twist and vibrate under unbalanced horizontal tension and the creep happen partially in the tower, which reveals the limitation of simulation and the necessity of real tower tests. The results can be used as the theoretical basis of monitoring and optimization of the transmission towers' health status.
