    Study of the Behavior of Concrete under Triaxial

    An experimental study of the confined compression behavior of concrete has been performed using 150 300 mm cylindrical specimens subjected to hydrostatic pressure in a triaxial cell and axial loading through a servo-hydraulic testing machine. A confining stress range of 0 to 60 MPa (about twice the uniaxial compressive strength) was employed to obtain the brittle-ductile transition behavior
