This research discusses the effects of both steel fibre and matrix strengths on fracture energy of highstrength concrete. The variables of experimental study were water/cement ratio, steel fibre strength and steel fibre volume fraction. The water/cement ratios of 0.35, 0.45 and 0.55, and steel fibre

β¦ Synopsis
A new experimental method for testing the dynamic tensile behavior of concrete at high strain rates was designed and established. By using this method, the dynamic tensile strength of concrete and its dependence on strain rates were measured and investigated. The experimental results indicate that the dynamic tensile strength of concrete is rate sensitive. The numerical simulation results have a good agreement with the experimental data and can be used for further research.
