PROBLEM: A simply supported beam has a width of 300 mm and an effective depth of 330 mm. It is reinforced at the bottom with a steel reinforcement area of 2464 mm?. Assuming steel covering to the centroid of the reinforcement is 70 mm. fc' = 34 MPa, and fy = 415 MPa. DETERMINE: • Ultimate Moment (Singly Reinforced) • Ultimate Moment (Doubly Reinforced) if the beam is reinforced with steel area of 1232 mm? (Compression Bars) at the top in addition to the existing steel area of 2464 mm2 (Tension Bars) at the bottom.

PROBLEM: A simply supported beam has a width of 300 mm and an effective depth of 330 mm. It is
reinforced at the bottom with a steel reinforcement area of 2464 mm?. Assuming steel covering to the
centroid of the reinforcement is 70 mm. fc' = 34 MPa, and fy = 415 MPa.
DETERMINE:
• Ultimate Moment (Singly Reinforced)
• Ultimate Moment (Doubly Reinforced) if the beam is reinforced with steel area of 1232 mm?
(Compression Bars) at the top in addition to the existing steel area of 2464 mm2 (Tension Bars) at the
bottom.
