STUDY OF MODE - I FRACTURE PARAMETERS IN HIGH PERFORMANCE CONCRETE

Abstract

In this paper an experimental investigation was carried out to study the fracture behavior of plane high performance concrete beams subjected to three point bending. In this investigation to study the effect of stress intensity factor and Fracture energy of concrete beams of various sizes with constant notch depth ratios at center. It was found that the stress intensity factor and fracture energy increases with the increasing of beam sizes and decreasing the failure stresses with increasing the beam sizes.
