Behaviour of Steel Transmission Line Towers under Earthquake Loads using Labview

Abstract

This paper deals with a detailed outline on the design, analysis, response and control measures of steel transmission line towers for the past few years. Due to the technological boom there led a change in our current way of lifestyle which makes necessary for the electricity to be available for 24x7. As the transmission line towers are one of the essential life line structures in the distribution of power from the source to the various places for several purposes and stand forth as lifelines of humans by enlightening our daily lives, it is essential to create a damage free transmission tower since, it is not imaginable to lead the life with absence of such electric serving systems. This review paper shed light on various case studies that deals with the collapse of transmission line towers which are stimulated by the action of wind and earthquake loads along with the creation of three dimensional models using the software. In addition detailed response of towers at different seismic zones under various wind zones are also discussed. The response of the transmission line tower differs depending over several structural bracing configurations which are highlighted in here through the comparisons. This paper also indicates about the response of towers with the foundation at soil surface which is termed as pile-soil-structure dynamic interaction. The present study is the outline of various literature researches over the analysis of steel transmission line towers by using the FEM analysis.
