Challenges for mitigating natural disasters on Overhead Transmission Lines - Earthquake

In general, in the design of transmission towers, wind load has a large effect on the calculation of the axial force of steel tower members. Even though Japan has experienced some of the world's largest earthquakes in recent years, notably the Kobe Earthquake in 1995 and the Tohoku Earthquake in 2011, there has been no record of overhead transmission towers collapsing because of seismic motion.
