The objective of this test program is to determine the feasibility of using MMFX reinforcing bars as shear reinforcement for reinforced concrete structures. To achieve this objective, comparative tests will be conducted for shear critical reinforced concrete beams using both conventional steel and MMFX steel reinforcements. The experimental program consists of nine reinforced concrete beams of each series are further divided into 3 groups of 3 beams each. Within each group, the variable would be the amount of shear reinforcement – the minimum, the intermediate, and the maximum amounts.
