Question

A reinforced concrete T-beam has the following properties:


Flange width, bf = 1,200 mm
Width of web, bw = 300 mm
Gross depth, h = 500 mm
Effective depth, d = 420 mm
Concrete strength, f’c = 21 MPa
Steel strength, fy = 415 MPa

10. If the beam is reinforced with (4) 3-20-mm-diameter bars at the bottom (in single layer), determine the
resulting depth (mm) of rectangular stress block at ultimate stage.
