Design Verification of Guyed Transmission Tower Using Nonlinear Analysis

Abstract

This paper describes the nonlinear analysis technique used for the design verification of a guyed transmission tower. This tower forms part of a new transmission line which is currently under construction. The nonlinear analysis technique is briefly described and the findings from the analysis are highlighted together with the resulting modifications to the original design. The findings from the nonlinear analysis predict a catastrophic collapse of the transmission tower based on the original design. This collapse would has resulted even if a full-scale testing of the tower was used to verify the design adequacy.
