Abstract:

Article Preview

Double layer stirrup confined concrete columns use two layers of stirrup, inside and outside, to constrain the core concrete. In this paper, in order to analyze the effect of double layer stirrups on the axial compression characteristics of concrete square columns, to determine the strength and deformation characteristics of double layer stirrup confined concrete square columns, and to establish the bearing capacity calculation equation for double layer stirrup confined concrete square columns, we designed 16 specimens to conduct axial compression test, from which a series of test data were obtained for double layer stirrup confined concrete square columns. We built the bearing capacity calculation equation for double layer stirrup confined concrete components on the basis of analysis and study and compared the calculated values with the test ones, and these data fit well; therefore, the study can provide reference for design and application of double layer stirrup confined concrete square columns.
