| Abstract |
Predictions for bending and shear behaviors of FRP concrete composites have been presented. The path-dependent confining effect on concrete has been determined by the failure surface of concrete using three-dimensional constitutive laws. FRP layers have been modeled using the mechanics of orthotropic laminated composite materials in two-dimension. For the prediction of bending and shear responses of FRP concrete composite members, an algorithm for the nonlinear flexural analysis using a fiber cross- sectional approach has been proposed. To predict shear strains from shear flow in a section, an effective width is calculated from the FRP thickness and the ratio of the average concrete modulus to the modulus of FRP jacket. The proposed model has been well predicted the bending and shear behaviors of FRP concrete composite members. |
