Abstract:
A probabilistic model for predicting the expected value and the variance of the postcracking tensile strength of fiber reinforced concrete is presented. Fibers are assumed to occur as a spatial Poisson process. Orientation of the fibers is assumed to be of three types: 1) randomly orientated in space; 2) randomly orientated within a prescribed plane; and 3) fibers all aligned along an axis. Analytical strength predictions are compared with existing strength data and the model assumptions are critically discussed.
