Resumen:
This paper develops an improved analytical model for predicting the damage response of multi-storey reinforced concrete frames modeled as an elastic beam-column with two inelastic hinges at its ends. The damage is evaluated in the hinges, using the concentrated damage concepts and a new member damage evaluation method for frame members, which leads to a meaningful global damage index of the structure. A numerical procedure for predicting the damage indexes of the structures using matrix structural analysis, plastic theory and continuum damage model is also developed. The method is adequate for the prediction of the failuremechanisms. Numerical examples are finally included
