The plasticity analyses for stability problems is differentiated from the conventional limit equilibrium method by the former in consideration of the soil's stress-strain relationship.
The paper presents a numerical method, named the Finite Strip Plasticity Coefficient Increment Initial Stress Method, to solve the elastoplastic stability ultimate loads of steel columns.
