In order to take this effect into account in a seismic assessment, the cumulative damage caused by the energy dissipation has to be quantified. In the paper a new damage model for seismic damage assessment of reinforced concrete frame structures is proposed. It combines deformation and energy quantities at the element level in order to take into account the cumulative damage. In the new model the damage index is expressed as a deformation demand/capacity ratio. The equivalent deformation capacity is used as the available deformation capacity which takes into consideration the influence of cumulative damage. It is defined as a linear function of an energy demand/capacity ratio, and its range of values is between the monotonic and cyclic ultimate drift. In order to apply the new model, data on demands and capacities are needed. Seismic demands can be estimated by a seismic analysis of the structural model. For the estimation of capacities, some experimental data are available in existing databases on reinforced concrete elements.
