ANALYTICAL MODEL FOR TENSILE BEHAVIOR OF STEEL-FIBER CONCRETE

An analytical model to predict the tensile behavior of steel-fiber concrete (SFC) is proposed. The model predicts the elastic and post-cracking behavior of SFC by considering the tensile load-extension responses of an uncracked and a precracked SFC specimen. Based on easily quantifiable material and mix parameters, the model is shown to give good predictions when compared to experimental results from SFC mixes using two types of fibers and to establish a rational basis for an idealized tensile stress-strain curve applicable to the analysis of SFC members.
