| Résumé : |
Fatigue cracking caused by stress concentrations in tubular joints has been observed in some
fixed platforms installed in hostile offshore environments. Consequently, the ability to assess the
magnitude of the stress concentration is prerequisite to dealing with the fatigue damage problem of
tubular joints, and to lead to reliable tubular joints.
The stress concentrations in offshore structures usually occur at the intersections of tubular members.
For some joints, the stress concentration can produce a maximum stress at the intersection as high as
thirty times the nominal stress acting in the members, and thus increase the risk of fatigue crack in the
tubular joints.
This work aims to study the distribution of the constraints and this article aims to study the distribution
of the constraints and the “hot-spot” points in the welded tubular joints subjected to a combined
loading of traction and rotational bending (inflection in the plan, inflection except plan and traction), to
simulate the real loading better. |
