CRITERIA FOR THE BEHAVIOUR OF PLAIN CONCRETE UNDER COMPLEX STATES OF STRESS

THE INFORMATION AVAILABLE ON THE MECHANICAL PROPERTIES OF CONCRETE UNDER COMPLEX STATES OF STRESS IS REVIEWED IN GENERAL TERMS. DEFINITIONS OF FAILURE OF CONCRETE ARE PROPOSED IN TERMS OF SUCH PARAMETERS AS DISCONTINUITY AND ULTIMATE STRENGTH ARE EXPRESSED IN TERMS OF SHEAR STRAIN ENERGY, MEAN NORMAL STRESS & LIMITING MAXIMUM TENSILE STRAIN SUGGESTIONS ARE MADE CONCERNING THE POSSIBLE RELATIONSHIPS BETWEEN PHENOMENOLOGICAL STRENGTH CRITERIA AND THE MODE OF CRACK FORMATION AND INTERPARTICLE BOND STRENGTHS, STRUCTURAL AND INTERPARTICLE MODELS, AND THEORIES OF CRACK PROPAGATION. THE ELASTIC AND CREEP BEHAVIOR OF CONCRETE UNDER COMBINED LOADING CAN BE READILY DEFINED AND UNDERSTOOD BY CONSIDERING SEPARATELY THE VOLUMETRIC AND DEVIATORIC COMPONENTS OF THE STRESS AND STRAIN TENSORS. /A/RRL/
