Abstract
Deep beams are structural members loaded as ordinary beams, but
they have smaller effective span to depth ratio ( /d). The ACI code, Europe
code and CIRIA GUIDE have provisions for design of deep beams in shear.
The main goal for both experimental and analytical work was to study the
influence of horizontal reinforcement on crack and deflection behavior of
deep beams with various ( /d) ratios and also to study the strength
parameters such as, first crack load, the ultimate failure load, deflection at
first crack load, deflection at ultimate load and mode of failure. This
objective has been achieved using models of experimental works that 6 deep
beams were tested with different shear span to depth ratio.
Prokon software program was used to analyze the results which were
compared with the experimental results obtained from the tested beams and
with the recommended formulae by CIRIA guide and Europe code. The
results were very close. It was evident from tests that the presence of
V
horizontal reinforcement increased ultimate shear. and the ultimate strength
decreased with increasing /d ratio in all beams tested.
