Finite Element Analysis of Hybrid Fiber Reinforced HPC Deep Beams under Shear Load

Abstract:

18 different groups of hybrid fiber (steel fiber and polypropylene fiber) reinforced HPC deep beams and 2 groups of HPC deep beams without fiber were made. The shear tests under the static load and the numerical simulation by ABAQUS were conducted. Good agreement are found between test results and simulation results.The results of finite element analysis indicate that with the increment of reinforcement ratio, the shear capacity of hybrid fiber reinforced HPC deep beams increases, but quite limited. The variation of shear capacity of hybrid fiber reinforced HPC deep beams is not obvious as the shear-span ratio changes (when ) . The increment of span-depth ratio can improve the shear capacity of hybrid fiber reinforced HPC deep beams, but only with small amplitude. All these regularities are similar to those of ordinary reinforced concrete deep beams.
