EFFECT OF STRESS CONCENTRATIONS ON THE STATIC AND FATIGUE STRENGTH OF CONCRETE IN COMPRESSION
THE EFFECT OF STRESS CONCENTRATIONS PRODUCED BY A CIRCULAR HOLE, ON THE STATIC AND FATIGUE STRENGTH ON PLAIN CONCRETE IN UNIAXIAL COMPRESSION, IS INVESTIGATED BY EXPERIMENTS. TESTS CONDUCTED ON PRISMATIC SPECIMENS SHOWED THAT THE ULTIMATE STATIC COMPRESSIVE STRENGTH AND THE FATIGUE STRENGTH IS NOT SIGNIFICANTLY ALTERED BY THE INTRODUCTION OF A STRESS CONCENTRATING HOLE. THE AIR CAVITIES AND MICROCRACKS INHERENTLY PRESENT IN THE CONCRETE EFFECT THE ULTIMATE STRENGTH AND DEFORMATION CHARACTERISTICS OF THE MATERIAL TO SUCH AN EXTENT THAT THE EFFECT OF THE ARTIFICIALLY INTRODUCED STRESS CONCENTRATIONS IS NEGLIGIBLY SMALL. /AUTHOR/
