Progressive Collapse and Residual Strength of Damaged Ship Structures Under the Action of Combined Loads
Abstract
This Research will focus on two important areas of research for intact and damaged ship strength these are:Damage Modeling Methodologies:- The removal of structure and the evaluation of the subsequent damage strength- The simulation of the damage mechanism, which will induce both residual stresses and initial distortions of the structure, including penetration damage, caused by the damage mechanism.Effect of Combined Loads- The Simplifies progressive collapse methodology will be extended to include the effects of combined loading on the structure, The combined loads to be incorporated will be the effects of hull girder horizontal and vertical bending loads combined with torsional loading, these environmental load conditions will be incorporated into the ProCol software to enable their combined effecton the progressive collapse of a ship~s hull girder to be investigated.- This capability will be demonstrated for hull girders (box girder structures) which have different structural characteristics such as single/double hull configurations as well as deck openings and structural damage.- These effects will be incorporated into the methodology for both the intact and damaged conditions.
