Reinforced Concrete Behavior and Design for Beginners!

Hi guys! I hope you find this video helpful! I plan to slowly introduce the concepts of concrete design on this channel based on CSA A23.3. We cover reinforced concrete behavior, failure modes, and the balanced condition. The following question is covered.

The reinforced concrete beam shown has an effective depth of 400 mm. Determine:

a) the balanced area of reinforcement (As).
b) the balance reinforcement ratio (p).
c) The factored moment resistance (Mr).

Given : fc' = 25 MPa, fy = 400 MPa,
Փc = 0.65, Փs = 0.85, Es = 200000MPa.

If you have any recommendations for future problems, or have suggestion for tutorials in the future, feel free to leave a comment!
