Abstract

Stirrups corrosion lead to degradation of ductility of concrete columns, the damage would transform from ductility to fragility, even to sudden destruction. In order to avoid concrete structure clasping because of the impact of earthquake and shocking, the mechanical property research of concrete columns confined with corroded stirrups is urgently needed. This paper mainly through axial compression test of the corroded stirrups confined prism concrete,study the different rate of corroded stirrups. The stirrups characteristic value and the damage protective layer, which influence the failure modes of concrete prism specimens,then do the analysis of the impact of various factors on the concrete confined with corroded stirrups stress-strain curve and its parameters, finally summarize the corrosion degradation mechanism of corroded stirrups concrete constraints.
