Abstract

Application of robotics welding in the fabrication of steel plate girders requires the modification of structural details such as the connections between the horizontal and vertical stiffeners. Placing a large gap at the horizontal-stiffener-ends improves the movability of welding robots. In this research the effects of the horizontal-stiffener-end-gaps on the local strains at the stiffener-ends are investigated by elasto-plastic large-deflection analysis. The developed finite element model is verified by experimental results and used to perform a series of virtual experiments. The results show that the large gap has a considerable effect on the local strains, depending on the shape of the initial out-of-plane deflection of webs.
