WebJan 7, 2024 · The present study investigates this finding for a PiP solution under a two-phase loading condition: in phase 1, the PiP solution is subject to 75 mm perpendicular indentation, and in phase 2, the resulting plastic damage in phase 1 is translated and induced longitudinally along the PiP system. WebSep 7, 2024 · The collision between tubular members and support vessels is the most important reason for damaged offshore structures. It can lead to serious consequences for economic losses and even human life or loss of structural strength [ 1 ]. Thus, the reparations of these structures are very difficult and time-consuming [ 2 ].
WebThe results of the test programs indicated that a significant amount in member deterioration could occur due to either dent or corrosion damage. The extent of the ability of a repair … WebAn analytical model of dented tubular members is constructed. Using this model, an ultimate strength interaction relationship between axial force and biaxial bending moments is derived. The implementation of this interaction relationship to take account of denting and bending damage in the analysis of nonlinear behavior of tubular space frames ...
WebSep 1, 2016 · The members used for legs and bracing structures are exposed to severely corrosive marine environments, including high humidity and high concentrations of airborne salt. To prevent the corrosion of structural members, heavy-duty coatings or sacrificial anodic systems are often applied to the steel.
