Recent developments in reassessment of jacket structures under extreme storm cyclic loading. Part 2: Cyclic capacity of tubular members

Tubular members with D/t ratio 35, 45, 60 and 80 were tested under controlled axial displacement described by an amplitude and a mean level. The material was structural steel to St. 52-3N, with minimum yield stress 345 MPa. The slenderness ratio of the specimens were in the range 50--70. During testing, the specimens were instrumented for measurements of longitudinal and transversal deflections, ovalization, and extreme fiber strains. Number of cycles to local buckling and through thickness cracking was recorded. Selected tests were simulated by use of the nonlinear beam-column FE program USFOS and the shell FE program ABAQUS. Comparisons were made to the corresponding test results. Monotonic and cyclic capacity criteria of tubular members are discussed on the basis of the results obtained.
