Abstract :
Today ,the process of seismic improvement and resistance has been accelerated in our country due to this fact that most current buildings has an old and non-standard context in our country . Studying the resistance is inevitable case especially in the columns which is the most important and critical structural components . So , this study is conducted to investigation the column's behavior of reinforced concrete under cycle loading before and after the improvement with polymer fibers . In this regard , one laboratory study was used in order to modeling verification .Then , the appropriate approach was examined in order to study the .Arrangement of resistance of Polymer fibers in Abaqus finite element software with simulation with several various models . After studying the hysteresis –bar curves transformation, load-displacement curve cover – transformation , ultimate load and the contribution of polymer fibers of models was found that samples those have polymer fibers have a greater ability to more loading bearing and also , have more absorb property and more energy amortization than samples without fiber.
