Challenge Problems
Push your limits with advanced challenges
Suppose a concrete specimen with a embedded steel bar of 12 mm diameter experiences a maximum pull-out force of 150 kN when tested. Calculate the average bond strength given an embedded length of 100 mm.
💡 Hint: Ensure units are consistent; convert everything to mm and N before calculating.
If a reinforced concrete structure loses its bond strength due to improper curing, how would that affect its load-bearing capacities? Discuss potential failure modes.
💡 Hint: Consider how steel and concrete work together to resist forces.
