To investigate the shear capacity and behavior of recycled aggregate concrete (RAC) deep beams reinforced with basalt fiber-reinforced polymer (BFRP) bars without shear reinforcements. A total of nine RAC deep beams with a 100% replacement ratio of recycled aggregate (RA) were constructed and tested in four-point bending. Four key variables, shear span-to-depth ratio ( ), longitudinal reinforcement ratio ( ), beam effective depth ( ) and compressive strength of RAC ( ), were determined to explore the failure modes, relationship between load and deflection, first cracking load and strain distribution in longitudinal reinforcements. Results from tests indicated that diagonal tensile failure was the predominant failure mode in BFRP-RAC beams. The shear capacity increased when the shear span-to-depth ratio decreased and the compressive strength of RAC increased. In the light of the experimental results, the model of strut-and-tie model (STM) was used to analyze and calculate. In addition, the shear capacity obtained by the experiment is compared with the calculated value by using STM. It showed that the calculated values are in good agreement with the test values of shear capacity of deep beams.
