CARRILLO, Julián; BARRERA-PENALOZA, Angélica P.  e  ACOSTA, Dago A.. Assessment of the splitting-tensile strength of ZP-306 steel fiber reinforced concrete. Ing. compet. [online]. 2014, vol.16, n.1, pp.261-272. ISSN 0123-3033.

Steel fibers reinforced concrete (SFRC) is a material with great potential to be used in low-rise concrete housing because the strength capacity of the walls is controlled by diagonal tension strength. The paper shows the results of an experimental study intended to characterize splitting-tensile strength of SFRC made of both ZP-306 fiber and local concrete. The experimental program included the tests of 52 cylindrical-shaped specimens. The study discusses the available predictive models and shows a statistical analysis to compare the predicted results with measured data. Based on trends of the experimental results, equations to estimate the parameters describing the backbone of the stress-strain behavior of SFRC under splitting-tensile strength are proposed. The equations have been developed in a versatile format to be included in a design code
