Seismic responses of transmission tower-line system under multi-component ground motions
Advances in Structural Engineering, 2023In this study, shaking table tests, theoretical research, and finite element modeling analysis were conducted on seismic responses of a transmission tower-line system under multi-component ground motions. The rocking component of ground motion was determined from the original seismic record by the wavelet analysis.

The Response Analysis of Angle Tower Line System by Broken Lines
Applied Mechanics and Materials, 2015The suddenly break makes the tension of tight lines rapid realease. The tower system will be subject to impact,but the design specification considers the break load only by static load.Beacuse of the angle between the sides of the transmission lines and the span changes, In order to solve this problem this paper uses the finite element program ANYSY/LS-

Dynamic Behavior of Transmission Tower-Line Systems Subjected to Insulator Breakage
International Journal of Structural Stability and Dynamics, 2018Ice loads attached to a transmission tower-line system can not only increase the vertical loads on the insulators, but also cause flashover to occur more easily. Both effects can lead to an increased probability of insulator breakage. In this paper, a finite-element model of a transmission tower-line system with three towers and four span lines under ...
