چکیده مقاله
In this paper comparing 3 rehabilitation techniques for retrofitting a 7 story building For this porpose considered a 7 story structural model with reinforcement concrete moment resisting frames system that designed by old seismic and concrete regulations Nonlinear static and dynamic and endurance time method analysis on the model was done According to the results, the model have not life safety level and need to retrofitting Have upgraded seismic performance level of the model by 3 methods The methods are: adding steel brace, adding concrete shear wall and adding concrete peripheral frame to the structure The retrofitting models evaluated by the new regulations and according to the results, the retrofitting models reach to the life safety performance level and target displacement have decresed
