Abstract:
This paper proposes a design method of steel fiber reinforced concrete structural elements which behave like beams. This method is based on the analysis of a cracked section. Three loading cases are considered: bending with or without axial load, shear, and concentrated force. After a brief presentation of the modeling, the experimental characterization of the material is studied. A uniaxial tensile test is used to get an intrinsic postcracking relationship. A statistical analysis of the tests leads to the definition of a characteristic stress vs. crack opening relationship, taking into account the scattering of test results, to be used in a design procedure. The design method is developed as closely as possible to the reinforced concrete design code, in order to allow an easy acceptance of these proposals. The procedure is based on the definition of material limit states: limit crack opening in tension, limit stress level, and limit strain in compression.
