A 300 mm X 450 mm exterior beam is reinforced with 2 - Ø20 mm and 1 - Ø25 mm bars on the first layer of tension reinforcement(larger bar is at the middle), 2 - Ø25 mm on the second layer of tension reinforcement, 3 - Ø25 mm for compression reinforcement and Ø12 mm for stirrups. From analysis the depth of the tension zone is 344 mm, if the tension steel has a yield strength of 420 MPa and the compression steel has a yield strength of 414 MPa. Determine the following using all the NSCP provision (larger bar always governs the spacing) to check and layout the beam: a. The compressive stress in the concrete. b. The depth of compression block C. Ultimate Moment Capacity of the beam.
