Dynamic Characteristics Analysis for 1000kV UHV Steel Tubular Tower under Seismic Loading

Abstract:

In this paper, the dynamic characteristics of a 1000kV UHV steel tubular tower with double circuit transmission lines on the same tower are analyzed under seismic loading with 8 degrees fortification intensity. Firstly, the finite element model of the tower and simulation of the earthquake are built in ANSYS finite element software. The dynamic characteristics of steel tube tower under Seismic Loads, such as the time-domain curves of displacement, velocity and force of UHV steel tower under Seismic Loads are obtained. The impact of 1000kV UHV transmission tower under nonlinear vibration of simplified conductor model is studied. The results can help to understand the damage forms of UHV steel tower under earthquake, to improve the capabilities to resist earthquake loads and severe damage of environmental loads under various field conditions for UHV steel tower.
