A ship structure is basically an assembly of stiffened panel elements and an estimation of the maximum load carrying capacity or the ultimate strength of these members is of the highest importance task for the safety assessment and rational design of the structure, In general, thin plates are often used in cruise ship/high speed vessel structures, for example at deck plating, side shell plating and inside structure, It has been known that reducing the thickness of plating dramatically reduces the buckling strength of a steel plate subjected to irv?plane compression and shear loading, and the ultimate strength of it is also expected to decrease.
In the present paper, to clarify and examine the fundamental buckling and progressive collapse behaviors of thin plates subjected to in-plane compression and in-plane edge shear load, a series of elastic and elastoㅡplastic large deflection analyses are performed applying nonlinear FEM codes, MSC Patran/Nastran,
On the basis of the numerical results, influences of yielding stress, thickness of plating, slenderness ratio, loading condition on the characteristics of the buckling/ultimate strength and progressive collapse behavior of steel plates, are discussed, It is shown that the ultimate strength formula developed for a flat plate can give a reasonable estimate of strength, when the newly defined double beta parameter considering the change of yield strength as well as slenderness ratio, It is our hope that the obtained ultimate strength formulation would be used as practical design guideline to predict ultimate strength of steel flat plates in the field of ships and offshore structures.
