Challenge Problems
Push your limits with advanced challenges
A concrete structure has been reinforced with steel to improve its tensile strength. If the compressive strength is measured at 6,000 psi and the tensile strength is observed at 600 psi, assess the structure's performance based on these values.
💡 Hint: Consider how lateral forces affect structures.
Given statistics that increased water in the concrete mix decreases compressive strength by 20%, calculate the new compressive strength if the original strength was 5,000 psi.
💡 Hint: Think about the percentage decrease and how to apply it.
