The difference between a singly and doubly reinforced beam
is that, in singly reinforced beam the reinforcement is
provided in tension zone only.But in some cases concrete
may not be able to withstand the compressive forces acting
on it and if applied bending moment is more than the moment
of resistance than reinforcement is provided in compression
zone also, which means doubly reinforced. Hence in doubly
reinforced beam, reinforcement is provided in both tension
and compression zone.
