Challenge Problems
Push your limits with challenges.
Question 1
If a cement concrete pavement requires tie bars with a total steel area of 2.0 cm²/m and the allowable tensile stress is 1750 kg/cm², what would be the required diameter of the tie bars assuming a circular cross-section?
💡 Hint: Remember to rearrange the area formula to solve for diameter.
Question 2
Consider a scenario where the bond stress for deformed bars increases to 30 kg/cm². Re-evaluate the length of a tie bar with a 1 cm diameter and 1750 kg/cm² allowable tensile stress. How would the increase in bond stress affect the length?
💡 Hint: Reflect on how stronger bond stress influences the anchoring requirement.
