Recentry, High Tension Steel is adapt to thin plate in the steel structure and marine structure is used widely, possibility that buckling happens great. Specially, Initial deflection of ship structure happens in place absence necessarily by heat processing of welding or cutting etc. As box style in thin plate structure. This Initial Deflection is element that exert negative impact when thin plate absence complicated nonlinear behaviour accompanied buckling. As a result, must idealize initial deflection that occurrence is possible to endow stability and accuracy in the hull structure or marine structure and reflect in early structure design considering buckling. Longi direction of compressive load interacts and analyzed finite element series that apply various kinds initial deflection shape measured actually on occasion that is arranged simply supported condition in this research. Applied ANSYS elasto-plasicity large deformation finite element method to be mediocrity finite element program as for analysis method and analysis control used in Newton-Raphson method & Arc-length method.
