FAQ

What is Gross Cross-Sectional Area of Column when Total Allowable Axial Load is Given?
The Gross Cross-Sectional Area of Column when Total Allowable Axial Load is Given formula is defined as the total area enclosed by the column and is represented as Ag=Q a/(0.25*f'c+f's*pg) or Gross area of column=Allowable Load/(0.25*Compressive strength+Allowable stress in vertical reinforcement*Area ratio of cross sectional area to gross area). Allowable load is the maximum working load that can be applied on the structure, Compressive strength is is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate, Allowable stress in vertical reinforcement is equal to 40 percent of the minimum yield strength, but not to exceed 30,000 lb/sq.in(207 MPa). and Area ratio of cross sectional area to gross area is the ratio of cross-sectional area of vertical reinforcing steel to gross area of column.
