In the building you are designing, you indicated that the overall size of a reinforced concrete beam must be 350mm wide by 600mm deep due to architectural requirements. You also indicated in your material specifications that the main deformed steel reinforcement bars, which are non-prestressed, should be PNS Grade 275 and that the concrete mix must achieve a compressive strength of 4,500psi.

Shown in the structural plans prepared by your structural engineer, the beam was indicated to be reinforced with 4-Φ25mm main rebars arranged in a single layer at the tension side, surrounded by Φ10mm rectangular closed-loop stirrups and provided with a clear concrete cover of 40mm all-around.
