Challenge Problems

Push your limits with challenges.

Question 1

A reinforced concrete beam must support a load that requires a compressive strength of at least 8,000 psi for safety. Given that standard concrete typically ranges from 3,000 to 6,000 psi, which special mix is advisable, and how might it be designed?

💡 Hint: Think about alternative concrete constituents that can enhance performance.

Question 2

You are tasked with designing a concrete structure that experiences cyclical loading. Consider how the properties of tensile strength and micro-cracking might influence your design choices.

💡 Hint: Consider dynamic loading effects as you examine different material responses.
