As per IS 456 ∶ 2000, for the design of doubly reinforced beam, the area of compression reinforcement Asc is given by _________,
where,
Mu = ultimate flexural strength of doubly reinforced section
Mu.lim = limiting moment of resistance
fsc = stress in the compression steel
d = effective depth
d’ = depth of compression reinforcement
1
Asc = \(\rm\frac{M u-M u, l i m}{\text { fsc }\left(d-d^{\prime}\right)}\)
2
Asc = \(\rm\frac{M u-M u, l i m}{\text { fsc }\left(d+d^{\prime}\right)}\)
3
Asc = \(\rm\frac{M u+M u, l i m}{f s c\left(d-d^{\prime}\right)}\)
4
Asc = \(\rm\frac{M u+M u, l i m}{f s c\left(d+d^{\prime}\right)}\)
