Challenge Problems
Push your limits with challenges.
Question 1
A 10-foot-long reinforced concrete beam has a cross-section that is 10 inches wide and 12 inches tall. If the steel reinforcement’s tension equals 30 kips at mid-span, what is the equivalent compression in the concrete at the same section?
💡 Hint: Apply equilibrium principles to balance the concrete and steel.
Question 2
Given that the failure strain for a concrete beam is 0.003, if the strain observed during loading is 0.0025, will the beam fail?
💡 Hint: Compare the observed strain with the failure strain.
