DOUBLY REINFORCED BEAM
![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
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:
Ø25 mm on the second layer of
