FAQ

What is 28-day Concrete Compressive Strength when Column Ultimate Strength is Given?
The 28-day Concrete Compressive Strength when Column Ultimate Strength is Given formula is defined as the strength of the concrete measured after 28 days of manufacturing and is represented as fc=(P0y*AOR)/(0.85*(Ag-AOR)) or 28 Day Compressive Strength of Concrete=(Ultimate strength-Yield Strength*Area of Reinforcement)/(0.85*(Gross area-Area of Reinforcement)). Ultimate strength is the maximum stress that a material can withstand while being stretched or pulled before breaking, Yield strength can be defined as follows, a straight line is constructed parallel to the elastic portion of the stress–strain curve at a strain offset of 0.002. The stress corresponding to the intersection of this line and the stress–strain curve is defined as the yield strength, Area of Reinforcement is an area of a weld that has weld metal added in excess of that specified by engineering drawings and codes and Gross area is the total area enclosed.
