     the behavior of a building during an earthquake depends on many factors including the characteristics of the ground motion, the configuration and dynamic characteristics of the structure, the hysteretic behavior of the structural components, the building’s non-structural parts, and the local soil behavior. when conducting seismic assessment studies, controlling the first factor involves selecting appropriate earthquake records and scaling to a specific level of intensity is one of the challenges in non-linear dynamic analysis of structures. this paper presents, how these differences among scaling methods effectthe results of timehistory analysis. three methods had been compared. the iranian standard no.2800, spectral correctionand spectral balance that are the usual scaling methods in iran. the studied model is 10 story dual-steel concentrically braced frames located in tehran.the records had been selected with respect to site consideration from bhrc.the results showed that first, the responses of non-linear analysis that consisted of base shear, inter story drift and lateral displacement is more than linear analysis. and second, the iranian standard no.2800 method had largest response among three methods. based on results, it is obvious that the iranian standard no.2800 procedure is conservative than the others.
