Abstract In order to investigate the shear performance of stainless steel reinforced coral aggregate sea-sand-sea water concrete beams (SSRCAC), ten specimens of SSRCAC beams were designed considering the effects of shear span ratio, spacing of stirrups, reinforcement ratio, and types of reinforcing steel, which included eight specimens with stainless steel reinforcing bars and two specimens with steel reinforcing bars. Through the test, load-displacement curves were obtained, and the shear capacity, strain distribution, and shear ductility were analyzed. The results show that the typical failure mode of the SSRCAC under shear is shear-compression failure, and the stainless steel stirrups of all specimens basically do not reach the yield strength. The development and the number of cracks in specimens with different shear span ratios show no significant differences. Shear span ratio has a large influence on the shear capacity and shear ductility of the specimens. With the shear span ratio λ of 1.0 and 2.0, the shear capacity of stainless steel reinforcement specimens is 18.4% and 64.4% higher than that of carbon steel reinforcement, respectively. The longitudinal reinforcement ratio has little influence on the shear capacity. Finally, considering the effects of stainless steel reinforcement and coral aggregate concrete, a design method for the shear capacity of SSRCAC beams was proposed, which can provide test basis for the application of such structures in marine engineering.
