Similitude coefficients of models Before, during and after designing, constructing and analysis of a structural model for shaking table tests, the most important aspect is to satisfy the similitude relationship. On the other hand, it is very difficult to meet all the demands exactly. Hence, some main factors shall be determined strictly first
