Through the large general nonlinear finite element analysis software ANSYS
the steel fiber reinforced concrete (SFRC)deep beams are analyzed. The constitutive model of concrete and reinforcement
as well as the properties of their elements are discussed in detail. During the simulation process the ANSYS parametric design language (APDL) is used to set up the finite element model; besides
the model of bond stress-slip relationship between steel bar and concrete which based on the Nilson bond stress-slip relationship theory is established
The simulation analysis and test results demonstrate that the good agreement can be found between simulation and test results
if Solid65 and Pipe20 element are used to simulate the SFRC and reinforcement respectively; and the three-dimensional nonlinear spring element Combin39 can simulate the interaction between steel bar and steel fiber reinforced concrete very well.
