Under longitudinal seismic action,the transmission tower was simplified as a generalized single degree of freedom model.The seismic response of the simplified model was calculated using the incremental form of the New-mark method.And the calculation result was compared with the response calculated by the finite element model of the transmission tower under the same longitudinal seismic action.The calculation result indicates that the tower top dis-placement calculated by the simplified model through the stepwise integration method is slightly larger than that calcu-lated by the refined model using general finite element software,and the difference is relatively small.This indicates that using the generalized single degree of freedom simplified model of transmission tower can effectively replace the o-riginal model under longitudinal seismic action.
