Shear capacity of reinforced brick aggregate concrete beams without any web
reinforcement and with varying ratio of web reinforcement was studied in this
investigation. Deflections of beams and cracks during the progress of loading
were recorded. Brick aggregate concrete beams with web reinforcement and
two layers of tensile reinforcement were found to have increased cracking shear
stress by a considerable amount. Equations for cracking and ultimate shear
stresses were suggested within the scope of this study. The experimental values
of ultimate shear strength of beams were compared with the values obtained by
equations proposed by ACI and other researchers. The equations proposed
herein were found to represent the test results better than those of other
researchers while remaining on the conservative side. It is hoped that the
equations developed herein will provide a rational and basic point of departure
from the prevailing concept and will help towards the formulation of a suitable
code to provide web reinforcement for brick aggregate concrete beams
