The authors have developed an initial hull structural planning and hull weight optimization system for bulk carriers and double hull tankers, and have established simplified evaluation methods for hull structural strength in the optimization process. In previous paper, simplified evaluation method of buckling strength for double bottom panels of bulk carriers is investigated. In the initial design process, evaluation of buckling strength for other stiffened panels besides double bottom panels is also needed. However, the previous simplified methods are applied only for double bottom panels of bulk carriers or similar them. Then, in this paper, we improve previous evaluation method of buckling strength for stiffened panels. As the result, good agreements of solutions between proposed method and finite element analysis are observed in the numerical example. And some influence by deflection of stiffener on stiffened panel is clarified.
