Problem:
Design a section of a concrete beam reinforced for tension only. The beam is simply supported on a span of 6.00 m and carries a load of 18 KN/m. Use Alternate Method of Design with n = 9. f'c = 20.70 MPa, Fy = 275 MPa. Use b = d/2.
Note:
Clear concrete cover for the beam: 40 mm
Clear spacing between rebars: 25 mm (minimum)
Minimum bar size to use as per ACI Code: 16 mm diameter
Design forflexure only.
