EFFECT OF STEEL STRENGTH AND OF REINFORCEMENT RATIO ON THE MODE OF FAILURE AND STRAIN ENERGY CAPACITY OF REINFORCED CONCRETE BEAMS

A THEORETICAL STUDY BASED ON IDEALIZED STRESS-STRAIN CURVES INDICATES THAT, WITHIN THE DUCTILE RANGE OF REIN- FORCEMENT RATIOS, THE STRAIN ENERGY CAPACITY IS ABOUT THE SAME IN REINFORCED CONCRETE BEAMS OF EQUAL STATIC BENDING STRENGTH REGARDLESS OF THE YIELD STRESS OF THE REINFORCING STEEL. THIS SUGGESTS THAT, FOR A GIVEN STATIC LOAD CAPACITY, A BEAM REINFORCED WITH BARS HAVING 60,000 PSI (4218 KG/ SQUARE CM) OR 75,000 PSI (5273 KG/SQUARE CM) YIELD STRESS WOULD BE VERY LIKELY ALMOST AS SATISFACTORY AS A BEAM REINFORCED WITH BARS HAVING 40,000 PSI (2812 KG/SQUARE CM) YIELD STRESS FOR RESISTING BLASTS, EARTHQUAKES, OR OTHER DYNAMIC LOADINGS. /AUTHOR/
