- Abstract
- The evolution of the response of reinforced concrete frames to seismic ground motions is studied using experimental data from shaking table tests of reinforced concrete model structure. The 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; the ground motion by its pseudoacceleration response surface. The distribution of the energy supplied to the structure by the shaking table is also described. Numerical methods for 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 in the specification of the filter parameters and in the numerical performance.
