VARIABILITY OF DEFLECTIONS OF SIMPLY SUPPORTED REINFORCED CONCRETE BEAMS

THE VARIABILITY OF ACTUAL DEFLECTION OF SIMPLY SUPPORTED REINFORCED CONCRETE BEAMS WITH RESPECT TO DEFLECTION CALCULATED BY ACCEPTED METHODS IS DISCUSSED. THE PROBABILITY OF THE DEFLECTION OF A PARTICULAR BEAM FALLING WITHIN A GIVEN LEVEL OF UNCERTAINTY IS EVALUATED BY ANALYZING EXISTING DATA AND FITTING A PROBABILITY DISTRIBUTION TO THE DATA. USING DEFLECTION CRITERIA OF ACI 318-71, THERE IS APPROXIMATELY A 90% CHANCE THAT DEFLECTIONS OF A PARTICULAR BEAM WILL BE WITHIN THE RANGE OF 20% LESS THAN TO 30% MORE THAN THE CALCULATED VALUE. THIS REPRESENTS A SLIGHT IMPROVEMENT OVER ACI 318-63. /ACIJ&P/
