The Effect of Chord Support Conditions on the Force-Displacement Characteristics of Tubular YT-Joints

摘要

The most common assumption adopted in relation to chord support conditions for individual tubular joint testing and analyses is that of simple supports. In studying the force-displacement characteristics of tubular joints the effects of alternative support conditions should be investigated, since it is known that brace loading paths do not typically remain radial. This paper presents an investigation of the effects of encastre chord support conditions (versus simply-supported) on both the force-displacement response and the failure locus of a representative tubular YT-joint. The work is relevant to the simplification of framework collapse techniques via localised representation of non-linear joint behaviour.
