**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**.
