24.1.1. Notation

Try these first

1. 1.

   What is the typical ratio of concrete's tensile strength to its compressive strength?

   Hint

   Think of a fraction based on the strengths.

2. 2.

   What does the ACI code provide for structural design?

   Hint

   It's a code established for safety.

3. 3.

   What is the tensile strength ratio of concrete to its compressive strength?

   • One-half
   • One-third
   • One-tenth

   Hint

   Think about the common fraction.

4. 4.

   Is concrete a good material for tension applications?

   • True
   • False

   Hint

   Recall the need for reinforcement.

5. 5.

   Given a specific load applied to a concrete beam, calculate the required steel reinforcement using the ACI guidelines.

   Hint

   Start with the established strength limits.

6. 6.

   Analyze a scenario where a section of a bridge is overloaded, leading to cracks. How would you redesign this section respecting ACI codes?

   Hint

   Consider both tensile and compressive forces in your redesign.
