Abstract:The axial|tension stress|strain full curves for the member of the steel fiber reinforced expansive concrete are measured successfully .The macroscopical progress and the micro|mechanism of the curves have been analyzed by the micro|cracking extension theory .Based on the test results, the numerical simulation for the stress|strain full curve has been carried out. The simulation equations are given, which show good agreement with the experimental results.
Keywords:concrete  stress|strain relation/axial|tension member
