Corrosion behavior of stirrups in corroded concrete beams exposed to chloride environment under sustained loading

This paper discusses the corrosion behavior of stirrups in two concrete beams under sustained loading, exposed to a chloride environment for 9 years. The cracking maps of concrete beams were recorded after 28 days and after 9 years, respectively. The corrosion maps of the stirrups were drawn and the cross-sectional losses of stirrups were measured after destroying the beams. The experimental results show that the horizontal legs of stirrups...
