Question
A reinforced rectangular beam with width b and effective depth d is subjected to service live
and dead loads (self-weight included) of wL and wD, respectively. If required, compression
steel bars are to be placed at a distance d' from the extreme compression fiber. Use fe' = 28 MPa and
fy 420 MPa.
b= 100 mm
d= 200 mm
d'= 300 mm
L= 320 m
wL 210 kN/m
wD= 220 kN/m
1. Solve for the area of tension steel bars using es 0.004.
2. Solve for the area of compression steel bars using es 0.004.
3. Solve for the area of tension steel bars using es = 0.005.
4. Solve for the area of compression steel bars using es = 0.005.
