Guide to design of Singly reinforced Sections

For “Singly reinforced sections” article series, we have covered the following:


Now we will move on with our discussion on “2nd Design method” for the design of Singly reinforced Sections.
We will follow a simple three-step procedure for the design of singly reinforced sections.

Step One:

Given that:

  • Dimensions of section (b and d)
  • Area of tensile steel (Ast)
  • Modular ratio (m)

From the figure above, we can see that the neutral axis is situated at the centre of gravity of a given section. Therefore, the moments of area on either side are equal.
