Experimental data are presented on the dynamic behaviour of a hysteretic SDoF system subjected to a succession of quasi-harmonic inputs. The specimen consists of a full-scale reinforced concrete column, having at the free end a large (15 tonnes) pivoted mass. Pseudodynamic and shaking table tests were performed, subjecting the column to inertial loading which was designed to cause it considerable damage. The responses obtained from both techniques are compared and the motion examined in terms of hysteretic equivalent damping and natural frequency degradation.
