| Abstract: | Nonlinear finite element analysis of reinforced concrete(RC) beams with different reinforcement ratios using the ANSYS computer program was conducted to study the effect of reinforcement ratio on flexure behaviors of RC beams.A series of key techniques on numerical simulation of RC beams were(presented.) The numerical simulation results of RC beam specimens were in agreement with the experimental and theoretical results.The development of RC beam stiffness,the failure modes, the stress distribution of sections,the crack propagation and stress development of reinforcement bars and concrete in the RC beams were analyzed.It is found that the numerical simulation technology presented is feasible. |
