Study on Three-Point Bending Numerical Tests of CFRP Reinforced Concrete Beam with Initial Crack
Based on extended finite element method (XFEM) of the finite element software platform-ABAQUS, three-point bending numerical simulation of CFRP reinforced concrete beam with initial crack has been made to predict the 3D crack propagation path. The numerical tests present the crack propagation path under ultimate load and crack damage modes of non-CFRP and some different CFRP plies. The results show that the strength of CFRP reinforced concrete beam is obviously improved and the crack which previous penetrate through doesnt penetrate through concrete beam under CFRP reinforce based on multiple optometric numerical simulation results. The results of this paper can also provide some foundations for damage mode, the ultimate load and CFRP overlay design of reinforced concrete beams.
