THE ASSESSMENT OF THE ULTIMATE STRAIN OF CONCRETE

The ultimate strain of concrete under short term loading is affected by a number of factors such as the position of the neutral axis (ie, the strain gradient), the percentage of steel reinforcement ("over" or "under" reinforced beams in flexure), the shape of the cross-section, the eccentricity of loading, the shape of the stress-strain curves and the stiffness of the structural testing system. The concrete strength has only a small effect. Time-dependent effects such as creep and rate of loading have not been included. The influence of test stiffness has been quantified. Analyses have been developed which enable the ultimate strain to be determined for axial loading, bending and combined axial load and bending. The predicted values compare favourably with ultimate strains measured in tests under a variety of different test conditions. The number of the covering abstract for the conference is TRIS no 394150.
