Summary:PROBLEM TO BE SOLVED: To improve the reproducibility of a target waveform signal by compensating for the reactive force of a specific frequency component received from a sample, in a vibration-testing apparatus that conducts shaking test on a structure. SOLUTION: A vibration-testing apparatus 1 includes a waveform generating device 6, a hydraulic vibration exciting device 3, a sample 2, a measuring device 5, and a control device 4 for controlling the movement of the hydraulic vibration exciter 3. Either a table 16, on which the sample 2 is mounted or the sample 2 is connected directly to the hydraulic vibration exciter 3. When the sample 2 generates an external force of a specific frequency component, a disturbance compensation filter 20 having the maximum value of gain at the frequency component, is added to an acceleration signal 18a of the table 16.
