Comparison of the Performance of Structures with a Special Lateral Bearing System of a Special Reinforced Concrete Frame with Special Shear Wall based on the Third Edition and the Draft of the Version No.۴ of the Iranian Earthquake Code

In this article the performance of structures with lateral bearing system of special reinforced concrete frame with special shear wall based on the third edition and draft of the fourth edition of the Iranian Earthquake Regulations has been studied. For this purpose, three structures of ۱۰, ۱۵ and ۲۰ three-dimensional floors under linear dynamic dynamics analysis was performed, in which the ۱۵-story structure is irregular. The structure is then analyzed with both of the above-mentioned regulations and then designed according to the ninth section of the National Building Regulations; Frame A of the three-dimensional structures is then subjected to push-up analysis. In the third version, taller structures, i.e. ۱۵ and ۲۰-storey structures, perform better than the fourth edition ۲۸۰۰, but this fact is the opposite for the shorter structure, i.e. ۱۰-storeys, i.e. the ۱۰-storey structure designed based on ۲۸۰۰ fourth edition has better performance than the same structure. But it is designed with the third edition. It should be noted that the structures are examined in the area away from the fault.
