Abstract
![CDATA[Previous research on fatigue of tubular joints has focussed mainly on empty welded joints subjected to various types of loading. Recent bridges have been constructed with welded tubular joints where the main chord is concrete filled to improve rigidity of the structure. This research investigates the behaviour of welded tubular T-joints made up of thin-walled square hollow section chord and braces with concrete-filled chords. The main chords are concrete-filled to simulate recent bridge constructions. High cycle fatigue tests of the T-joints are carried out under cyclic in-plane bending load in the brace. Stress concentration factors, failure modes and design data of the T-joints with concrete-filled chord are compared to those of empty tubular joints from previous research. Fatigue design is from an analysis of test data.]]
