| Abstract: | Nonlinear finite element program for steel fiber reinforced concrete (SFRC) composite beams is compiled with C ++ language, considering material nonlinear. By using the program, the nonlinear analysis for SFRC composite beam model from initial loading, cracking, yielding to failing is carried on calcuating the cracking, ultimate load and deflection. The calculated results correspond well to the experimental results. |
