Q) Differentiate between singly reinforced beam and doubly reinforced beam.
Q) Differentiate between singly reinforced beam and doubly reinforced beam Aspect Singly Reinforced Section Doubly Reinforced Section Definition Has reinforcement only in the tension zone. Has reinforcement in both tension and compression zones. Moment Resistance Designed to resist only the moment that tension steel can handle. Designed to resist higher moments than singly reinforced can bear. Usage Used when the section depth is sufficient and moment demand is moderate. Used when section depth is restricted or higher moment capacity is needed. Steel Placement Tension steel only (at the bottom in beams). Tension steel at bottom and compression steel at top. Ductility Less ductile. More ductile due to compression reinforcement. Cost Econ...
