Seismic Responses of Multiple-Circuit Transmission Tower-Line System
Applied Mechanics and Materials, 2014Compared with normal transmission towers, the multiple-circuit tower was higher and heavier,it also had a longer crossarm. Response spectral method was taken to analysis the transmission tower-line’s response under earthquake.The results obtained from single tower and tower-line system under the earthquake were compared with each other，such as the ...

Strain Rate Effect on Transmission Tower-Line System under Earthquake
Advanced Materials Research, 2011Using ABAQUS software, three dimensional finite element model of a transmission tower-line system is created. Nonlinear seismic responses under three seismic records with and without strain rate effect are studied. The results show that the strain rate effect on the transmission tower-line system is more obvious with an increase in intensity of the ...

At present, the effect of tower-line coupling is neglected in seismic vibration control with TMD for transmission tower-line system. However, for large crossing transmission tower-line system(LCTL), the neglect can affect the performance of TMD. In this study, a typical FEM model of LCTL is established.
