In this article I will discuss some useful point that how to calculate steel for different structure in civil engineering.
Some points for Steel calculation
1: Deduct the concrete cover for slab if u find the length of main bars and distribution bars in slab or beam etc.
2: Crank length of slab = l / 5
3: Crank length for beam or slab is 1.41 Remember where d is the depth of the slab or beam ( but not the diameter of steel)
4: The beam bottom extra length should be take with 1/6
5: The beam top extra length should be take with 1/3
6: The Stirrups hooks should be take with 135 degree angle.
7: Spacing of distribution bar and main bars can take from the center of steel.
8: Steel calculation should be do with this formula ( DxD / 162 ) Where D is diameter of steel in mm.
9: The Stirrups hook length should be take with 9D where D is dia of steel.
10: Densit of steel is 7850 kg/m3
