ABSTRACT
Idea of push-pull type joints in application to steel truss made with RHS is the base to this research. Simple laser made T RHS joints are tested. Experimental evidence of such joint behaviour tested in natural scale is described. Geometry and material properties of the tested connections are given. Axial-deflection curves are presented. Yield line local push mechanism on front wall and as the alternative front and bottom wall chord section is used to the theoretical estimation of the failure load. Preliminary design model for calculation and a prediction of joints resistance is proposed. Theoretical and experimental results of joints resistance are shown. Finally, some conclusions with regard to the possibility of resistance improvement by the double side joint solution are given.
