NUMERICAL APPROACH TO THE COMPLETE STRESS-STRAIN CURVE OF CONCRETE

THIS PAPER PRESENTS THE EXPERIMENTAL JUSTIFICATION OF TWO PREVIOUSLY PUBLISHED FORMULAS FOR THE ESTIMATION OF THE COMPLETE STRESS-STRAIN DIAGRAM OF CONCRETE. MORE RELATIVE CURVATURE IS PROVIDED IN THE DIAGRAM FOR CONCRETES OF LOWER STRENGTHS. TAKEN INTO CONSIDERATION IS THE FACT THAT THE VALUE OF THE UNIT STRAIN INCREASES WITH INCREASING CONCRETE STRENGTH. THE RESULT OF THESE REFINEMENTS IS THAT THE STRESS-STRAIN DIAGRAMS CALCULATED BY THESE FORMULAS FIT BETTER THE EXPERIMENTALLY OBTAINED DIAGRAMS AND WITHIN WIDER LIMITS THAN THE SIMILAR FORMULAS AVAILABLE IN THE LITERATURE. /AUTHOR/
