Abstract :
The modal analysis and seismic time history analysis were performed of cathead transmission towers with different tower legs heights by the software Open SEES, the material nonlinearity and geometrical nonlinearity were considered in model. The results show that with the increase of the height of the cathead tower, the fundamental period increases linearly, the tower top maximum displacement and tower bottom main member peak axial force are reducing, the higher tower have better cushioning effect.
