This paper describes an improved analytical model for predicting the nonlinear response of multistory reinforced concrete frames, based on the concepts of isotropic continuum damage mechanics combined with plasticity theory. A frame member is considered to consist of an elastic beam with two inelastic hinges at its ends, according to the conventional lumped plasticity models. This model uses the conventional plastic damage, adapted to the case of frames.
