Doubly Reinforced Concrete Beam Design (ACI 318-14)
Determine the required reinforcement steel area for a concrete beam carrying service dead and live loads. First, check if singly reinforced beam section is suitable. If not, try doubly reinforced concrete beam section by adding compression reinforcement. It is desired that the section for this cantilever beam be tension controlled. Compare the calculated values in the Reference and the hand calculations with values obtained by spBeam engineering software program from StructurePoint
