EFFECT OF INITIAL IMPERFECTION ON ULTIMATE STRENGTH OF STIFFENED PANELS UNDER LONGITUDINAL COMPRESSION

The stiffened steel panel will experienced high stress when the deck and bottom shell of ship hulls experience bending compressive stress due to hogging and sagging bending moment. Failure of stiffened panel will also will lead to failure of ship hull girder. Therefore, stiffened steel panel has...
