Moment Resistance for Unique Concrete Beams!

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 moment resistance and design assumptions in this video. The following question is covered.

A concrete beam with an irregular cross section has 100 mm x 100 mm notches at the corners within the compression zone. Assuming the beam is properly reinforced, Determine the factored moment resistance (Mr) with the given material properties:
( fy ) = 400 MPa.
( fc' ) = 30 MPa.
( Փc ) = 0.65.
( Փs ) = 0.85.

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