| Abstract: |
| A model of simulating the interaction between the reinforcement and concrete based on contact condition has been established in this paper.Some basic mechanical parameters of the reinforcement and concrete: bond stiffness,frictional coefficient,shear strength,radial extrusion pressure and softening coefficient,are determined in the test;sequentially,four processes of the pull-out specimen: elastic phase,local cracking phase,internal congesting phase and complete debonding phase,are analyzed in the FEM simulation.The calculated results are coincident with those of test and validate the rationality of the computation model,which can solve the problem that has not been explained by traditional continuum theory. |
