STUDY ON STRUCTURAL CHARACTERISTICS OF TUBULAR STEEL TRUSSED TOWERS WITH ECCENTRIC CONNECTIONS

Abstract

The present paper discusses structural characteristics of the tubular steel trussed tower with gusset plate typed connections, specially having an eccentric joint applied to the crossing between column and braced members. Firstly, it is clarified effects of eccentric bending moment to the column buckling strength by horizontal loading tests and non-linear analyses for the model planned to make its column member buckle at first. Secondary, it is discussed effects of local deformation of the column tube at the eccentric joint to static and fatigue bearing strength of its connection. Lastly, based on results of the present study, it has been authorized fundamental data for the practical design in case of application of the eccentric joint to such the steel tower.
