Ultimate Strength Equation for Longitudinally Stiffened Panels under Combined Axial Load, In-plane Bending and Lateral Pressure

Author(s): J.K. Paik, A.K. Thayamballi and B.J. Kim
Abstract: The aim of the present paper is to develop the advanced ultimate strength equation for longitudinally stiffened panels subject to combined axial load, in-plane bending and lateral pressure. The collapse pattern of the stiffened panel is classified into six groups. This paper considers that the collapse of stiffened panels occurs at the lowest value among the various ultimate loads calculated for each of the collapse patterns. The panel ultimate strengths for all collapse modes are calculated separately, and are then compared to find the minimum value which is then taken to correspond to the real panel ultimate strength. The post-weld initial imperfections (initial deflection and residual stress) are included in the developed panel ultimate strength equation as parameters of influence. The validity of the developed equation is checked by a comparison with experimental and numerical results.
