Abstract

In this study, impact behaviors of layered concrete beams with more steel fibers in the tensile zone (0.75% of 30mm by volume) were assessed. This analysis was achieved using LS-DYNA, an explicit finite element analysis program. And the material tests were performed to obtain the material properties. These results were used as a basic input data of material models in LS-DYNA. The results indicated that the impact resistances, flexural strength, ductility, etc., increased steeply when higher steel fiber volume fractions were applied. In the case of the layered concrete beams, the higher impact resistances were obtained than those of the normal steel fiber reinforced concrete beam with an equivalent steel fiber volume fraction. The analysis results were also corroborated with the impact test results, which had similar in terms of maximum deflection.
