Abstract: This paper presents the fiindings from a damage behavior study carried out in a quasi-static laboratory on a single bay single storey reinforced concrete frame without infill. Applying quasi-static lateral forces induced crack damage in the model. The energy dissipation that followed resulted in an increased equivalent viscous damping. Hysteretic models proposed by various authors for such closed forms overestimate the equivalent viscous damping. In this study, distinct from hysteretic models, the results obtained from the quasi-static test were converted in to a damage index, which included the maximum deformation and cumulative damage. This index gave higher and a more sensitive estimate of the damage behaviour than other indices that were based either on stiffness degradation or on cumulative damage.
