The results of eight reinforced concrete deep beams tested under four point
loading condition are reported. The test beams were simply supported and were
made with self compacting concrete (SCC). The variables were; web reinforcement
and anchorage of tension reinforcement. The test beams were divided into four
groups according to the web reinforcement. Each group consists of two beams, one
with the anchorage of tension reinforcement and the other without. The nominal
cross section was 100 x 300mm and the clear span length was 1100mm.
Deflections of beams and cracking patterns were monitored during the tests at
different stages of the monotonic loading until failure. The results showed the
significance of the web reinforcement and anchorage of tension bars on the
strength and failure behavior of SCC deep beams. The ultimate strength of beam
without web reinforcement increased to 39% by adding anchorage to the
longitudinal tension reinforcement. While the ultimate strength of the beam
increased to 16% by adding anchorage to tension reinforcement for beams having
web reinforcement that consists of stirrups with horizontal reinforcement
