Laboratory Testing of Ultimate Capacity of Dented Tubular Members
Publication: Journal of Structural Engineering
Volume 118, Issue 4
Abstract
During the last few years a project on experimental investigation of the ultimate capacity of dented beam‐columns was performed at Veritas Offshore Technology and Services A.S. in Oslo, Norway. The purpose of the project is to determine experimentally the moment versus axial force versus rotation relationships for dented tubular steel members. The diameter thickness ratio of the tubular tested corresponds to that of typical members in jacket structures with D/t ratios of 31 and 47. The steel quality of the pipes is St 52 and St 35 respectively. A total of 35 ultimate load tests are performed. Four tests are performed with undented specimens for verification of the test procedure. Eighteen tests are performed with a dent depth equal to 10% of the pipe diameter and 13 are performed with a dent depth equal to 20% of the diameter. The information from these tests may be used in the evaluation and verification of residual strength of damaged offshore structures.
