This study examines stiffened panels with crack damage in a longitudinal stiffener. The crack is installed near a joint line with a transverse frame. Finite Element analysis (FEA) is performed to clarify the collapse behavior and residual strength of the cracked panels subjected to lateral water pressure and in-plane compression. The influence of the dimensions of the stiffened panel and the number of stiffeners on the collapse behavior is examined. The results indicate that the crack does not affect the bending strength of a thick stiffened panel under lateral pressure, but may reduce the strength of a thin panel. The crack reduces the compressive ultimate strength when the panel has such deep stiffeners that the overall buckling deformation does not increase. In a panel with small stiffeners, the crack constrains the growth of the overall buckling deformation and increases the ultimate strength. Simplified methods are proposed for estimating the reduced strength of the stiffened panel with the crack under in-plane compression. The benefits of the methods are validated through comparison with FEA results.
