Buckling behavior of plates and shells is one of the important characteristics in analysis of any structure. One the most significant parameter that must be considered in buckling phenomenon is imperfection. In this paper the effect of imperfection on buckling load of steel rectangular plates under uni-axial in-plane compressive loading is investigated by numerical and experimental methods. The plates were free on two opposite sides and simply supported at the load side whereas the opposite side is either clamped or simply supported. This means that the plate primarily exhibits a type of column’s buckling.
