A shaking response is estimated with high precision by performing a shaking test f or combining and estimating a shaking characteristic of a partial structure of an object under test obtained through a shaking test and a shaking response of the whole structure which is numerically modeled. In a shaking test apparatus and method, a structure under test comprises a partial structure and a numerical model which is virtually connected to the partial structure. First, a vibration model corresponding to the partial structure is assumed, the numerical model and the vibration model are combined to construct an overall-system model, and then the vibration response of the overall-system model is calculated. On the basis of the calculation result and the signal input from a waveform oscillator, the partial structure is shaken by using a shaker. The displacement and reaction force of the partial structure are measured by a displacement gauge and a load cell, the vibration model is corrected on the basis of the measurement value and the overall-system model is reconstructed. This procedure is repeated to construct the overall-system model with high precision.
