CAMBER/TOLERANCE RELATIONSHIP ON THE ACLU PROJECT

THE AMERICAN COLLEGE OF LIFE UNDERWRITERS' ADULT LEARNING RESEARCH CENTER (A SIX-STORY OFFICE BUILDING IN BRYN MAWR, PA.) IS A TYPICAL CAST-IN-PLACE REINFORCED CONCRETE BUILDING THAT REQUIRES THE SUBSEQUENT MECHANICAL TRADES TO SQUEEZE THEIR EQUIPMENT BETWEEN A LEVEL CEILING AND A DEFLECTED SURFACE. ON THIS PROJECT MANY CAREFUL MEASUREMENTS OF BEAM AND SLAB SOFFITS VERIFIED THAT DEFLECTIONS WERE PREDICTABLE, BUT THAT CAMBER IS NOT ALWAYS EQUIVALENT TO THE SPECIFIED, NORMALLY ANTICIPATED TOLERANCE SUCH AS ACI 347 INDICATES SHOULD BE ACHIEVED. DATA ARE TABULATED FOR 45 BUILDING LOCATIONS ON SIX DIFFERENT FLOORS DEMONSTRATING THAT UNDER PRESENT CONDITIONS, ACTUAL TOLERANCES ABUSE THOSE RECOMMENDED BY ACI 347. /AUTHOR/
