Abstract: This research on axial compression performance of concrete confined by stirrups at cryogenic temperatures provides an experimental basis and data support for the analysis and design of reinforced concrete structures, especially for axial compression members in a cryogenic temperature environment. Through tests on three groups of reinforced concrete specimens with different stirrup ratios under axial compression loading, stress-strain and load-displacement curves were developed under different temperatures. After temperature parameters were non-dimensionalized, the impacts of stirrup characteristic value on concrete strength, peak stress and ductility were further studied. The conclusions can be summarized as follows: when the temperature decreased, the peak stress and elastic modulus of the concrete confined by stirrups increased, while peak strain decreased, leading to an increase in the brittleness; when the stirrup characteristic value increased, the strength, peak strain, and ductility all increased, but elastic modulus didn’t change dramatically. Finally, the experimental and theoretical stress-strain curves agreed well.
