This paper provides and evaluates record's scale factors associated with four classes of soil with different domain of shear wave velocity considering two common scaling methods based on the uniform hazard spectrum (UHS) method. The evaluation has been conducted based on the deviation in structural responses of the models. The assessed scaling methods are the ones which are broadly used by design professionals as well as they are compatible with commonly used performance assessment codes. As well, the records were selected from a very frequently applied list of ground motions. It has been recognized that although by reduction in shear wave velocity in the soil classes the scale factors increased, the amounts of deviation in structural responses are not depended on the class of soil. So, it could be concluded that the reliability of the structural responses is independent from shear wave velocity in the soil class.<\div>

This study attempts to answer the question of distinguishing appropriate intensity measure parameter for performance–based design or assessment, taking into account the efficiency aspect. The comprehensive comparative tables proposed in this paper could be an effective support in the decision making procedure for intensity measure selection, comprising most of the frequently utilized intensity measures for low–rise buildings with different fundamental periods. In addition, since some specific intensity measures are commonly applied in codes, the amounts of standard deviation computed in this study could be very beneficial in answering the question of being worthy to consider another intensity measure, to improve the certitude of structural responses, noting expansion in calculationefforts.
