Evaluating the plasticity of concrete beam-column connections reinforced with FRP composite rebars

Abstract: Moment frame connections have high share to withstand deformation caused by earthquakes. Hence, connections of reinforced concrete structures must have sufficient plasticity in addition to resistance. Observations after earthquakes and the results of tests prove that structural damages have been more observed in the connections area. Implementation of reinforcement in limited volume of connection area is difficult and hence improving the behavior of the connection areas has been among the major issues discussed in structural engineering. In addition, corrosion in the bad environmental conditions is one of the main difficulties in implementing steels in concrete arming. Among alternative materials, FRP rebars that have higher durability, were given attention in recent years. In this study, the behavior of the element has been compared in these conditions by modeling the connection area with steel and FRP rebars.
