The shaking table (digitally controlled) can input three-dimensional (horizontal + vertical + pitch) excitation. The working area of the shaking table measured 4 m × 3 m, and the maximum load capacity was 10 t, while the maximum horizontal and vertical acceleration were 1.0 g and 0.7 g, respectively. The operating frequency range was 0–50 Hz.
