Description
The earthquake resistance of transmission tower has been often discussed from the viewpoint of reinforcing the foundation of steel tower, but there are still few studies considering the damping characteristics of the tower. This paper focuses on the tuned mass damper (TMD) which has been adopted for seismic reinforcement of bridges in recent years. The purpose of this research is to improve the seismic performance of steel tower by giving the high damping to the tower. We construct a single tower model considering the influence of transmission line, and then simulate the vibration characteristics and seismic behavior of the tower by the eigenvalue analysis and the dynamic response analysis. The results show that the transmission tower with TMD can reduce its own response effectively and drastically. This study concludes that the collapse of steel tower can be avoided by using the optimum damper in the design of the transmission tower.
