One of the major concerns in seismic testing is whether the loading conditions imposed on a structure adequately represent those that might occur during a major earthquake. Response simulation using shaking tables can resolve many of these concerns for some types of structures. The recently developed pseudo-dynamic test method may enable these advantages to be extended to a broader range of test specimens. This paper outlines some recent advances in this method, discusses some of its limitations and identifies future research areas.
