Degree of Bending (DoB) in Tubular KT-Joints of Jacket Structures Subjected to Axial Loads
The fatigue life of tubular joints commonly found in offshore industry is not only dependent on the value of Hot-spot stress (HSS), but is also significantly influenced by the through-the-thickness stress distribution characterized by the degree of bending (DoB). The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stres...
متن کاملdistribution of stress concentration factors along the weld toe of tubular kt-joints in truss bridges
many research works have been accomplished so far on the computation of stress concentration factors (scfs) for various types of tubular joints. almost all these studies have focused on values of the scf at the saddle and crown positions, and they have ignored the hss at other locations along weld toe. however, scf distribution is very important for predicting the fatigue crack growth, determin...
متن کاملStatic Strength Analysis of Tubular T-Joints Using Ansys
A Finite element analysis has been done using ANSYS, to study the static strength of an offshore tubular T-joint. The strength of T-tubular joints with circular cross section tube chord with circular cross section tube brace is investigated. To determine the joint strength of these T-joint subjected to tension, compression, in -plane bending and out-of-plane bending loading cases have been carr...
متن کاملFatigue Life of Repaired Welded Tubular Joints
In this study, the effect of repair on fatigue life of tubular joints is investigated. Six cracked specimens precedently subjected to fatigue loading undergone to weld repair. Two of those specimens were shot peened before primary fatigue loading. It is shown that repair gives rise to about 150% increase in fatigue life for original specimens while the increase of fatigue life for shot-peened ...
متن کاملStress Concentration Factors in Uniplanar Tubular KT-Joints of Jacket Structures Subjected to In-Plane Bending Loads
In the present research, data extracted from the stress analysis of 46 finite element models, verified using test results obtained from an experimental investigation, were used to study the effect of geometrical parameters on the chord-side stress concentration factors (SCFs) of central and outer braces in uniplanar tubular KT-joints of offshore structures subjected to four different types of i...
