Collapse Load of Tubular Trussed Tower Designed by a Conventional Method

Abstract

The elastic-plastic large deformation behavior and the collapse load of a tubular trussed tower which has legs of unequal length and mechanically severe shape is studied by a numerical analysis. An original method for three dimensional steel structures and members with closed thin walled section is used to investigate the behavior. It is shown that the tower designed by a conventional method has a sufficient strength for the design loads.
