Iran is located in a high-risk seismic region. The severe damage caused by recent major earthquakes has increased the importance of seismic evaluation methods and design procedures. To enhance seismic evaluation methods, it is necessary to provide acceleration records which are compatible with a design spectrum. In this paper, a new method is proposed to generate compatible records with a design spectrum. The method is based on dividing the response spectrum of a record into several period ranges and finding the scale factor for each range. The proposed method is used for seven real acceleration records to generate seven synthesized acceleration records, with a response spectrum compatible with the design spectrum of Standard 2800 (3 edition) for soil type 3. Besides, seven artificial acceleration records are generated using SIMQKE I. The nonlinear dynamic behavior of two 12-story RC buildings, which were designed by a direct displacement based (DDB) method and standard-2800, are used for comparison between the two groups of records. Results state that the proposed method is suitable for analyzing and designing structures without a noticeable increase in the values of the input energy of the real records.
