According to Degarmo and Black (2003, p.56), reinforced bars with high ductility and tensile strength are often preferred because they allow the materials to be rolled, drawn or made longer without breakage. Generally the tensile strength of reinforcing steel can be measured by dividing the cross sectional area of the steel tested by the stress exerted on the material. The amount of stretching force (N) needed to break the test material can then be measured and recorded. Experimental Procedure The tensile testing experiment involved calculating mechanical properties of three specimen samples of reinforcing steel bars which were designated as N12, R12 and RW11.9. Some of the main mechanical properties that were tested include yield stress, modulus of elasticity, elongation, tensile strength, ductility and reserve length. Specimen N12 was a hot rolled deformed bar that was derived from a microalloy TEMCORE material. Generally such steel alloys are made by adding expensive alloys such as Silicon, Carbon, Manganese and Vanadium to the steel. ...
