Abstract: In this paper, a non-linear 3-D finite element analysis (FEA) model usingABAQUS (Hibbit, Karlsson and Sorensen, Inc. 2003) was developed to predict the cyclicbehavior of shear wall structures. In this FEA model, SPRING element is used to simulatethe constraint deformation due to fiber reinforced polymer (FRP) wrapping, andimproved concrete stress-strain curve is considered to account for the improvement ofstrength and ductility of concrete under FRP confinement. A damaged plasticity-basedconcrete model is used to capture the behavior of concrete under cyclic loading.Method to identify shear failure due to FRP debonding and FRP rupture in FEA is alsoproposed. The model is validated using the results from the experimental study. It isshown that the proposed model can predict the shear failure and cyclic hysteresisbehavior of GFRP-wrapped shear wall reasonably well.
