This calculator is useful for design of one way solid slab simply supported on both ends. This calculator assumes normal weight concrete and uses FPS/US Customary Units. It uses Strength Design method as per ACI 318 code of American Concrete Institute.

Effective depth is measured from the top edge to the centroid of tension rebar. This calculator uses the concept of Whitney's stress block and measures the depth of stress block "a" from the top edge. The user of this calculator is advised to comply with ACI guidelines for beam thickness, rebar spacing and cover etc.

This calculator also determines the minimum area of tension rebar required for crack control and balanced steel area required for a balanced section. The calculator also determine the value of RPlease enter the values in the appropriate units mentioned in the form given below and start calculations.
