Dynamic Compressive Behavior of FRP-Confined Concrete under Impact and a New Design-Oriented Strength Model
Source abstract
Abstract
The dynamic mechanical properties of fiber-reinforced polymer (FRP) confined concrete were experimentally and theoretically studied using a 100-mm-diameter split Hopkinson pressure bar (SHPB) apparatus. As test results turned out, the dynamic strength of FRP-confined concrete was improved significantly. Within the mean strain rate range of 50–130 s −1 , the dynamic strength increased with the rise in strain rate. With same strain rate, the strengthening effect was influenced by confining ratio. The optimal confining ratio of AFRP-confined concrete is 0.264, once beyond this limit, the failure pattern will be changed, and the dynamic strength will be decreased. In addition, a modified model was proposed for dynamic strength of FRP-confined concrete, which agrees with the test results well.
