A reinforced concrete beam having a width of 350mm and a overall depth of 600 mm is reinforced with 3-25mm compression bars & 8-25mm tension bars. Concrete covering is 60 mm from the centroid of the bar group. Unit weight of concrete is 23.60 Kn/M3. Concrete Strength, fc’ = 21 MPa, Steel Strength, fy = 415 MPa. Other than the weight of the beam, the beam will support a uniform live load.       A. Determine the balanced tension steel area.   B. Determine the Ultimate Moment Capacity of the beam.

Question

A reinforced concrete beam having a width of 350mm and a overall depth of 600 mm is reinforced with 3-25mm compression bars & 8-25mm tension bars. Concrete covering is 60 mm from the centroid of the bar group. Unit weight of concrete is 23.60 Kn/M3. Concrete Strength, fc’ = 21 MPa, Steel Strength, fy = 415 MPa. Other than the weight of the beam, the beam will support a uniform live load.

 

 

 

A. Determine the balanced tension steel area.

 

B. Determine the Ultimate Moment Capacity of the beam.
