description

Experimental results on the shear behaviour of the steel trusses in composite steel-concrete beams are presented. Preliminarily tensile tests have been performed on specimens reproducing different types of welded joints. Tests are addressed to investigate on the bearing capacity of the welds and on the local instability problems that can arise in the elements of the truss. A FEM model is also presented in order to reproduce the behaviour of the steel truss subjected to shear load. Moreover, simplified relations are used to obtain the ultimate load on the welds for the different type of node and simplified models based on truss behaviour are used to foresee the stiffness and the strength of the steel truss specimens.
