Abstract:
Uniaxial compression experiments for the steel fiber reinforced high strength concrete(SFRHSC)were conducted by using a multifunction servocontrolled testing machine. The volume fraction Vf of steel fibers of SFRHSC ranges from 0 to 3%. On the basis of the stress-strain curves the constitutive equations were established. These equations satisfy all the characteristics of those curves. The equations have two key parameters A and B. Both A and B increase as Vf increases, which clearly shows that the strength and toughness of the matrix are enhanced by steel fibers. The larger the A, the greater the difference between the compressive strength fc and elastic limit stress; the larger the B, the flatter the descending portion of the curve. Finally, the mathematical expressions of A, B and Vf, fc are also presented.
