STEP 6

GRID A

• From base to the first floor the maximum Ast = 7027
• So we can provide 10nos of 32mm dia bars = 10*804=8040mm^2
• From the first floor to terrace the maximum Ast = 4800
• Provide 6 nos of 32mm dia bar = 6*804=4824mm^2

GRID B

• From Base to terrace the maximum Ast = 5046
• Provide 8nos of 32mm dia bar = 8*804=6432mm^2

It can satisfy the entire span
