Abstract

The load-displacement curves for concrete under biaxial (tension-compression) loading conditions were measured using rectangular notched specimens and wedge splitting procedures. The polylinear inverse analysis method was used to determine the tension softening diagrams from the load-displacement curves. The observed differences in the biaxial fracture behavior between natural and crushed aggregate concrete are analyzed and discussed. The influences of compressive loading on softening properties, such as the shape of the curve or tensile strength, were also investigated from the analytical results.
