Compound strip method (CSM) is applied for geometrically nonlinear problems of stiffened plates. CSM is variation of well-established finite strip method that allows introduction of stiffeners into the strip.This semi-analytical procedure promises more accurate results than purely numerical methods.
Equations of balance are derived using the principle of minimum of total potential energy and Newton-Raphson iterative procedure is utilized for their solution. The stiffeners are modeled so that they may lie anywhere within the strip which helps to increase the flexibility in mesh generation. The formulation is applicable for rectangular plates stiffened with longitudinal and transverse beams and supported on columns. The proposed method is investigated and validated through several examples.
