Abstract

Axial repeated loads tests of 5 cross-shaped concrete columns confined by stirrups were carried out. I analyzed the failure process, failure characteristics, skeleton curve and ductility of columns and set up the formulas of ductility coefficient. The results showed that with the increasing of reinforcement characteristic value, the failure type was changed from oblique failure to longitudinal failure, the peak load and displacement of cross-shaped columns increased, the descending segment of skeleton curves turned to be more flat, the calculated results of ductility coefficient were in good agreement with the experimental results. The formula can be used to calculate the ductility coefficient of cross-shaped concrete columns confined by stirrups under axial repeated loads.
