Abstract: Shear behavior of reinforced recycled concrete (RRC) beams are investigated
experimentally in order to contribute to establishing design method for shear by comparing
with that of reinforced concrete beam made of virgin aggregate. Ten reinforced concrete
beams are prepaired using manmade recycled fine and coarse aggregates as well as those from
site. The major factors are combination of aggregates, water to cement ratios, effective depth
and usage of expansive additive. Experimental results indicate that RRC beams without
stirrups is decreased in shear strength by 20% and empirical design code overestimates the
shear strength of recycled aggregate concrete. On the contrary, shear strength of RRC beams
with stirrup is almost the same as those of RC beams in experimental results, while modified
truss theory underestimates the ultimate shear strength of beams by 30% on the condition that
shear failure is defined by yielding of stirrup.
