Abstract | The majority of tubular joints commonly found in offshore jacket structures are multi-planar. Investigating the effect of loaded out-of-plane braces on the values of the stress concentration factor (SCF) in offshore tubular joints has been the objective of numerous research works. However, due to the diversity of joint types and loading conditions, a number of quite important cases still exist that have not been studied thoroughly. Among them are multi-planar XT-joints subjected to out-of-plane bending (OPB) moment loading. In the present research, data extracted from the stress analysis of 81 finite element (FE) models, verified using experimental test results, was used to study the effects of geometrical parameters on the chord-side SCFs in multi-planar tubular XT-joints subjected to three types of OPB moment loading. Parametric FE study was followed by a set of the nonlinear regression analyses to develop three new SCF parametric equations for the fatigue analysis and design of OPB-loaded multi-planar XT-joints. |
