Answer / sp

first we will calculate the total area of the steel
required with nos of bar of 20 mm and area of one bar of 20
mm.
and then divide with area of one bar of 16 mm.
the result will be nos of bar of 16 mm dia.

Answer / shailesh

In beam /column
Total cross section area of 20mm=total cross section area of
16mm

(3.14/4)*20*20=(3.14/4)*16*16*no

No=400/256
=1.56

Answer / baljeet yadav

Answer / yogesh tripathi

P1/A1=P2/A2, where, P is spacing and A is Area of bar.
So that we will minimize the specing between bars according
this formula.
