Different researches show that during an earthquake, the seismic input energy of structure strongly affects the seismic destructive which foresight them completely is not possible by using nonlinear response spectrum or drift methods. Because of the recent studies show that energy concepts be able to explain about all effective parameters on seismic behavior of structures, therefore this energy concept became an effective and attractive basis considered by optimum distribution of damage in structures. Since almost all structures will have nonlinear behavior under strong ground motions, therefore study such behavior of structures is necessary. Purpose of this paper is assessment of damage distribution quality, drift and hysteretic energy in stories of concentrically braced frames which have designed based on Iranian Earthquake Code No. 2800 (Third Edition). The results show that maximum stories drift and the ratio of hysteretic energy to input energy have increased to two and three respectively and despite uniform distribution of strength in frames height, damage and hysteretic energy distributions diagrams are not uniform and centralization of energy and damage are indicated in first story, which increasing the number of stories, this centralization is decreased and appear the more uniform distribution of this energy in frames height.
