Abstract:Since most of the non-uniform shaking table tests use a multi-point shaking table array system, the seismic response of underground structures under non-uniform earthquakes is restricted by the conditions of the test equipment and it is difficult to carry out extensively. Therefor, an experiment technology by using conventional single shaking table to consider the traveling wave effect is proposed. In order to verify the feasibility of the test method, the model box is simplified into a driving block and a driven block connected by springs and dampers. The calculation formulas for the spring and damping parameters of the two-mass model and the three-mass model are theoretically deduced, and the accuracy of the formulas are verified through numerical cases, and then a series of small single shaking table test of the two-mass and three-mass model are designed and implemented. The experimental results show that the dominant frequency and time delay of the acceleration response of the driven block are very close to the target value under the excitation of simple harmonic load, which shows that the method of implementing the traveling wave effect through the spring damper is feasible. The research results can provide some reference to non-uniform shaking table test under traveling wave.
