Abstract Based on the dynamic similitude theory, a detailed deduction process on the similarity scale factors between the prototype and 1∶50 scale model was presented. A hammering modal test and a series of seismic shaking table tests were successively carried out to obtain the dynamic characteristics and the seismic responses of this 1∶50 scale model. Meanwhile, the corresponding dynamic behaviors of the prototype were also systematically analyzed by the use of the ANSYS software. The investigation results indicate that the 1∶50 scale model can accurately predict the dynamic performances and seismic responses of the prototype with small error and can provide a reliable testing model for the following studies.
