Abstract:
Reports on a nearly completed study begun in 1989 to improve the ductility of reinforced concrete members by mixing fibers with concrete. In this study, the bending test of fiber-mixed reinforced concrete beams made with two kinds of steel fiber and aramid fiber by reversal static loading has been done. From the test results obtained so far, it is shown that the ductility of fiber-mixed reinforced concrete beams is improved over that of normal reinforced concrete beams. It is calculated that the ductility factor of fiber-mixed reinforced concrete beams can be computed if the tensile strength and ultimate compressive strain are known.
