1. A cantilever R.C. beam is 280 mm x 500 mm deep and is reinforced with 4- 20 mm diam bars for tension. Using an effective depth of d = 450 mm, determine if the 2.50 m long beam is adequate to carry a uniform load of 15 KN/m and a %3D concentrated load of 10 KN at the cantilever end. Use f'c = 21 MPa, fy = 275 MPa. Neglect the weight of beam. Use n = 9 (Alternate Method of Design) %3D

1. A cantilever R.C. beam is 280 mm x 500
mm deep and is reinforced with 4- 20 mm
diam bars for tension. Using an effective
depth of d = 450 mm, determine if the 2.50
m long beam is adequate to carry a
uniform load of 15 KN/m and a
concentrated load of 10 KN at the
cantilever end. Use f'c = 21 MPa, fy = 275
MPa. Neglect the weight of beam. Use n =
9 (Alternate Method of Design)

2. Referring to #1, using the same data,
determine if the cantilever beam is
adequate based on strength design 2001
NSCP specifications. The 15 KN/m load is
DL while the 10KN load is LL.
