Base displacement is one of the typical deteriorations of a transmission tower. So, we have been developing a health monitoring system using inclinometers for monitoring the base displacement. The prototype system developed by the authors has been currently monitoring the inclination of structural members of transmission tower in several fields. The threshold for inclination used in the current system is determined by FEM analysis. The objective of this research is to confirm the validity of the threshold by conducting a real scale experiment of forced base displacement. In this research, the relationship between the base displacement and the inclination of structural members is investigated. The amount of increment in stress due to the base displacement is also studied. These results give us a knowledge for the appropriate sensor arrangements and show the validity of the current threshold.
