    Abstract

    An experimental investigation was performed on dynamic compressive stress–strain relationships for steel fiber reinforced concrete (SFRC) with various steel fiber volumetric contents under cyclic compression at a medium strain rate. Results indicate that the mechanical properties of SFRC are not only affected by strain rates but are also influenced by loading modes. The envelope curves of unconfined SFRC are different from those of specimens under monotonic compression. Dynamic compressive strength presents a non-monotonic enhancement with increasing steel fiber content. On the basis of the experimental results of cyclic compression at a medium strain rate, the elastic–plastic damage constitutive equations are proposed to describe the dynamic compressive stress–strain relationships of SFRC under cyclic compression at a medium strain rate. These equations match the test results well.
