Abstract: One class of X-joint, commonly known as trunnion, with the brace subjected to combined shear and moment loads, is designed to transfer the sling forces to the adjoining structural members and system during the lift installation of a jacket or deck structure. Present offshore codes provide design guidelines for X-joints subjected moment and other loads, except shear loading. In this paper, the in-plane moment strengths of X-joints computed using the ABAQUS software are shown to correlate closely with results published by Vegte (1995). Based on the parametric studies carried out to investigate the influence of applied shear/moment ratio on the strength of X-joints, it is found that the reduction in in-plane moment capacity for increasing shear load ratio, Q/Qp, is less significant for X-joints with smaller β. For joints with β=0.25, there is a strength reduction up to 25% while joints with β=0.73 indicate a reduction up to 55%.
