Abstract:
This study presents the experimental results of steel fiber reinforced concrete specimens subjected simultaneously to compressive and tensile stresses. The main parameters examined are: the combination of the two direct stresses biaxially applied to the specimens causing fracture, and the amount (percent by volume) of steel fibers. Results of tests on 160 specimens confirm that fiber reinforced concrete strength under combined tension and compression is far greater than plain concrete strength. Steel fibers increase concrete strength in the critical stress region from one to three times, depending on the amount of fibers.
