Stress strain relationship of very high strength concrete

In ultimate strength design of concrete structures the stress strain relationship is one of the main material properties required. Since part of the concrete compression zone would be subjected to stresses beyond the peak stress, information on both the ascending and descending portions of the curve are of importance. For normal strength concrete (with compressive strengths up to 50 MPa) the shape of the curve in uniaxial compression is well established. An experimental program designed to obtain the full range stress strain relationship of very high strength concrete with strengths up to 130 MPa at 90 days under triaxial conditions is reported here. Also reported are the ascending portion of the curves under uniaxial compression. The results are compared with other proposed relationships for high strength concrete and an expression is proposed for the stress strain relationship of very high strength concrete subjected to active confinement.
