Question
I want to design residential building for that i want to know what is the formula of calculation loads and how much steel is required in 1 Sft.

Answer
Hi Amit,

Fot calculating loads, you need to assess the self (dead) weight of the structure by calculating the volume and multiplying with the density, and you need to apply the imposed (live) loads in accordance with usage and the applicable standards/codes.

How much rebar is required per sft depends on the spans and loading, but on average you can assume about 80 to 100 kg per cubic metre of concrete for a residential building.
