A reinforced concrete T-beam has the following properties:
Flange width, bf = 800 mm
Flange thickness = 100 mm
Width of web. bw = 275 mm
Gross depth, h = 500 mm
Effective depth, d = 420 mm
Concrete strength, fc = 21 MPa
Steel strength, fy = 415 MPa
If the beam is reinforced with 6-28-mm-diameter bars at the bottom, determine the resulting depth (mm) of rectangular stress block at ultimate stage. Write the answer to the nearest whole number.
