The evolution of the response of reinforced concrete frames to seismic ground motions is studied using experimental data from shaking table tests on a reinforced concrete model structure. Structural response during shaking is analyzed and correlated with the input table motion. The response is characterized by means of the average vibration period and the effective acceleration while the ground motion is characterized by its pseudoacceleration response surface. The distribution of the energy supplied to the structure by the shaking table is also described. Numerical methods of filtering shaking table and seismic signals are studied. Two widely used techniques, namely the window method and the Ormsby filter, are examined and combined into a numerical scheme with greater flexibility for specifying the filter parameters and numerical performance.
