Energy dissipation capacity of reinforced concrete columns is investigated under inelastic cyclic displacements. Experimental data is obtained from twenty column specimens tested under constant amplitude displacement cycles and from three column specimens tested under variable amplitude displacement cycles. The effect of failure mode, displacement ductility, material properties and detailing on the energy dissipation capacity of columns is investigated first under constant-amplitude loading. A simple model is developed for predicting the cyclic energy dissipation capacity under constant-amplitude inelastic displacement cycles. Then an analytical procedure is introduced for estimating the energy dissipation under variable-amplitude displacement cycles by using the energy dissipation capacity under constant-amplitude displacements. The proposed procedure is verified with test results.
