A steel bar of 20 mm Fe415 grade is embedded in a concrete block of M20 grade. The bond stress τbd = 1.2 MPa as per IS : 456-2000, for mild steel in tension. The length of embedment is 1m. The maximum pulling force that can be applied on the bar is ___________ kN
  • a)
    113
  • b)
    114
Correct answer is between '113,114'. Can you explain this answer?
Verified Answer
A steel bar of 20 mm Fe415 grade is embedded in a concrete block of M...
Force required to pull out the bar from concrete
P1 = τbd × 1.6 × π × d × l = 1.2 × 1.6 × π × 20 × 1000 × 10-3
P1 = 120.63 kN
Force required to break the bar
P2 = 113.43 kN
Hence maximum pulling force = Min. of P1 & P2
= 113.43 kN
