The dimension analysis method is adopted to induce the similarity relation about structural dynamic test, based on the similarity ratio of damping, the earthquake excitation and any physics quantity related to the dynamic test can be calculated between the structure and the model.

The primary method and applicable fields of dynamic test and dynamometer in dynamic machinery equipment are summarized.

With respect to the reinforcement of civil defense works,the dimensional analysis method and the differential equation method are employed to derive and analyze the similitude scales for the setup and dynamic test of a reinforced concrete slab-column system model.
