The aim of the present research is to create a fiber concrete construction with non-homogeneous fiber distribution in it. Traditionally fibers are homogeneously dispersed in concrete, but in many situations fiberconcrete with homogeneously dispersed fibers is not optimal (majority of the added fibers are not participating in the load bearing process). Layered beams with different short fibers content in plies were fabricated. The beams were tested under four point bending conditions. Increasing external applied load macro-crack is started at the bottom side of the beam. This is why the maximal fiber content in the prepared beams was concentrated at the bottom side of the beam. Prediction results were discussed.
