Recently, there are a lot of cases found where transmission towers are damaged due to the effects of abnormal weather. Therefore, the authors propose an advanced transmission tower monitoring system that utilizes inclination sensor technology. This paper summarizes the analytical model of transmission tower that is able to represent the relationship between the base displacement and the change in the inclination angle of structural members measured in the full-scale base displacement test. Furthermore, 20 analytical models of transmission steel towers are developed and the threshold values that prevent the material damages are estimated.
