Deep beams are structural elements loaded as simple beams in which a significant amount of the load is carried to the supports by a compression force combining the load and the reaction.
As a result, the strain distribution is no longer considered linear, and the shear deformations become significant when compared to pure flexure.
Floor slabs under horizontal load, short span beams carrying heavy loads, and transfer girders are examples of deep beams. Deep beam is a beam having large depth/thickness ratio and shear span depth ratio less than 2.5for concentrated load and less than 5.0 for distributed load. Because the geometry of deep beams, their behavior is different with slender beam or intermediate beam.
