Based on reanalysis of the shear test results of reinforced concrete beam specimens made of recycled coarse
aggregates reported in the literature, this study points out that the strut-and-tie modeling (STM) provisions
developed for natural coarse aggregate concrete can be applied to recycled coarse aggregate concrete with no
reduction in the efficiency factors of bottle-shaped struts. The experimentally obtained strut efficiency factors in
beams made of recycled coarse aggregate concrete were comparable to those in beams made of natural coarse
aggregate concrete. The study also highlights lack of conservatism in the STM provisions of current design
codes irrespective of the type of coarse aggregates used
