Seismic Responses of Transmission Tower-Pile-Soil Dynamic Interaction

The mechanical model of Soil-Pile-Structure interaction of transmission tower-cable system is presented in this paper, and the corresponding equations of motion are derived, in which the nonlinear characteristics of soil is included in the dynamic time history analysis. The computer program for the system is complied and used to calculate the earthquake response of an actual transmission tower. The results of numerical calculation are compared with and without considering soil-pile-structure interactions, and show that the dynamic interaction should be taken into account in the soft foundation.Copyright © 2003 by ASME
