In recent years the research concerning the numerical solutions of the buckling strength of the stiffened web plates has been rapidly developed by use of I.B.M., and systematic stability coefficient's values have been published by K. Kloppel, J. Scheer and others. A method is herein developed for determining the stability of the longitudinally stiffened plates under shearing forces by proposing the simplified formulas applicable to the actural design. The basic equations of the stability coefficient taking out from datas up to this date is exhibited as following form. [numerical formula] where [numerical formula] [numerical formula] β=a/b, a=length of web plate, b=width of web plate q=(number of longitudinal stiffeners)+1, μ_L=EJ_L/N・b N=Et^3/12(l-v^2), t=thickness of plate, J_L=moment of inertia of longitudinal stiffener b_0=b/q, b_0'=minimum width of panel plate. The simplicity of the proposed formula has a tendency to give rather large safetyside errors in the case of large values of β or μ_L, but it does not bring out much errors to be methoned of in the range of applicable design. The formula can be applied to the transverse stiffeners such as vertical stiffeners of plate girders, and derived formula can be represented in the form. [numerical formula] where J_0=moment of inertia of vertical stiffeners a_0=spacing of vertical stiffeners.
