Abstract

Beam is classified as a deep beam if the beam has a larger depth in relation to spans. Deep beam differ from normal beam in which they are most likely to have strength controlled by shear rather than flexure. In addition, deep beams have been widely used as a transfer girder in offshore structures as well as foundations. Moreover, the failure behaviour of deep beams is significantly not the same from the one which are shallow due to the geometry and load transfer mechanism. This research presented the stress-strain distribution results for four identical high strength self compacted concrete (HSSCC) deep beams. From the indicated results, it could be concluded that, the strain distribution at mid span was non linear at all loading increments and the compression strain at the top of mid span section increased with the increasing of the applied load. There is a disturbance in tension strain values due to the crack propagation and the deformation of this area. From the stress distribution of deep beam, it could be indicated that neutral axis is at the middle third of the beam depth and is tends slightly to the upper direction.
