Abstract

A series of three-dimensional soil−foundation−structure coupled analyses of transmission tower is performed to investigate the strength of the entire system. Nonlinear finite element analysis is conducted to capture the progressive failure of the foundations and the buckling behavior of the tower. In the series of analyses, various landforms, load directions and neighboring of the piles are considered to evaluate the performance of the foundation under actual condition. The coupled analysis of the entire system reveals that the displacement of the foundation is influential on the collapse of the tower. Moreover, it is pointed out that the critical component in the collapse of the entire system drastically changes depending on the mode of external loads.
