This paper provides and evaluates a very simple and practical procedure for selecting ground motions in addition to compare two common scaling methods based on the uniform hazard spectrum (UHS) method and presents scale factors of the selected ground motions associated with these methods. Evaluation of the proposed approach of record selection demonstrates the efficiency of the proposed method. It also presents proper method of scaling for each soil condition and engineering demand parameter and the obtained scale factors could be utilized directly from this paper in the other studies in this field without any excessive calculational attempts.
