Currently, there is no general agreement on a theory describing the response of reinforced concrete
members without web reinforcement. Many structural systems are usually performed using
empirical or semi-empirical expressions provided by codes of practice that do not consider the
influence of many governing parameters. In this paper, a comparison between values of current
experimental shear strength and those of various international design approaches like ACI,
Canadian, FIB and the method proposed by Sudheer, Zararis ,Zsutty ,Shah ,Bazant and Russo.
Eighteen simple span high strength reinforced concrete “HSRC” deep beams without web
reinforcement were tested and analyzed under two static point loads at mid-span of the beam to
examine the contribution of various parameters on the shear capacity of HSRC beams. The main
studied parameters are f‟cu=50 MPa, three values of tension reinforcement-ρ%-(0.73%,1.21%
&1.83%) and shear span to effective depth ratio-a/d-( 2,1.5 &1). As a conclusion of this paper, ACI
and FIB code provisions for shear in HSC are safe for use with the exception that CSA should be
used with care. Despite numerous studies, there is still a need to develop a clear understanding of
the shear behavior of HSC beams without web reinforcement. Therefore, this experimental program
was arranged to evaluate the shear behavior and to increase the shear database on HSRC deep
beams.
