a. Determine the design moment capacity of the reinforced concrete beam shown in Figure 1(a) if it is reinforced with 4-28-mm diameter in tensio and 2-16-mm diameter in compression. b. If the beam will carry the loading pattern shown in Figure 1(b), what safe load W can it carry based on the design moment in part (a)?

Question
a. Determine the design moment capacity of the reinforced
concrete beam shown in
Figure 1(a) if it is reinforced with 4-28-mm diameter in tension
and 2-16-mm
diameter in compression.
b. If the beam will carry the loading pattern shown in Figure
1(b), what safe load W
can it carry based on the design moment in part (a)?
Use fc = 21 MPa, fy = 276 MPa and effective cover of 50 mm for top and bottom bars.
Assume the load W to be ultimate. Neglect weight of beam.
