Test results of nine stiffened panels loaded axially show that the Perry-Robertson formula accurately predicts the collapse load and the direction of collapse provided the imperfection term ©¯ is interpreted in a logical manner. A new expression for ©¯ is derived. Four other panels were tested in bending or with combined bending-axial loadings. Simple rules are also presented for the design of stiffened panels with these
