ANALYSIS OF TRANSMISSION TOWER DYNAMIC CHARACTERISTIC
Authors
Li Haiwang Chen Kaixuan
Abstract
Since snow disaster to the electric power facility’s huge destruction, the dynamic properties of the electric transmission tower are analyzed with the ANSYS procedure,in order to consider the influences on the dynamic properties of the tower wrapped by a variety of ice thickness.The analytical results indicate the natural frequency of tower will reduce with the increase of wrapped ice thickness,especially when wrapped ice thickness reached 50-60 mm. The decrease range more than 30 percent. The change of dynamic characteristics have a greater influence on for the dynamic response of structures under action of the earthquake and wind.This paper lays a good foundation for the later dynamic properties research under action of earthquakes or wind.

Transmission tower ANSYS modeling and finite element analysis
Authors
CHEN Qi WANG Xin-fang WEN Ming
Abstract
The paper gets static analysis on truss model and truss-beam model of the transmission tower(straight tower) based on the large finite element analysis software——ANSYS,and discusses on the results of the truss model and truss-beam model's max comprehensive stress,max comprehensive displacement and integrity distribution situation,so as to find the same and different points between two kinds of models.

STUDY OF TRANSMISSION TOWER MODELING IN ANSYS AND DYNAMIC CHARACTERISTICS
Author:
Feng Yunwei
Abstract
The natural vibration periods of transmission tower structure are obtained using FEM and the wind pressure regulation factor can be determined by programming interface program which can transform the data of full stress to ANSYS and process the mode analysis.The spatial frame model and mix-element model are established in the example,and the mode analysis results are compared with the results by experience formula.It indicates that the mode analysis results in accord with criterion values better,and the experience formula results are smaller than them.

Influence of Bolted-Joint Slippage on the Response of Transmission Towers Subjected to Frost-Heave
Authors
K.I.E. Ahmed, R.K.N.D. Rajapakse, M.S. Gadala
Abstract
Slippage of bolted joints is an important factor in the behavior of transmission towers. Field inspections of towers located in the northern regions of Canada show substantial frost-heave induced displacements. The conventional structural analysis software solutions for tower leg axial forces, based on idealized joint behavior under field-observed frost-heave induced displacements, are excessively large, implying tower failure in some cases. However, field inspections show structurally stable towers, and design engineers often consider joint slippage as the main reason for this discrepancy. In this paper, the experimental slippage behavior of transmission-tower bolted joints investigated by Ungkurupanian (2000) is incorporated into a non-linear joint finite element and applied to study the behavior of transmission towers under working loads by using the finite element method. The analysis shows that tower-leg joint slippage has a significant influence on tower behavior by either reducing the load carrying capacity or significantly increasing the deflections under working loads. On the other hand, joint slippage has a positive effect on towers subjected to frost-heave induced displacements, as the resulting member axial forces are much lower than those corresponding to rigid joints.
