| Sumario: | In concrete structures in order to reduce the story drift, one of the simple methods are using a shear wall. Due to the fact that the concrete shear wall has a suitable stiffness, it can be limited the displacement of the story as much as the seismic demand. The use of GFRP polymer composite rebar in concrete shear walls of along with its many advantages, can be useful for increasing the durability and service life of such structural elements. Also, in concrete shear walls where the congestion of steel reinforcement causes problems in vibration and quality of concrete, replacement of polymer composite rebar with steel rebar due to its high tensile strength, thus reducing the number and cross-sectional area of reinforcing element.In this study 43 shear walls was analysed subjected to pushover analysis to determination the amount of ductility and lateral strength. 20 models of them reinforced by GFRP polymer composite reinforcement rebar and 20 models reinforced by steel reinforcements, and for three last models difference concrete compression amount was used. The results show that the reinforced shear wall with GFRP polymer composite reinforcement has the ability to withstand displacements and greater lateral force than the steel reinforced steel walls. |
