Challenge Problems
Push your limits with advanced challenges
A reinforced concrete beam fails under a specific load. Analyze how the assumptions of bonding and plane sections being maintained could influence the load-bearing capacity of the beam if these assumptions were violated.
💡 Hint: Think about the structural integrity if conditions aren't as they are assumed.
Design a simple reinforced concrete beam under the assumption that it maintains equilibrium. If the steel reinforcement's yield strength is doubled, how does this affect the required concrete strength?
💡 Hint: Examine how increased strength of one material affects the performance of another.
