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.
