Abstract: 
This paper presents experimental results of a highly corroded beam subjected to chloride environment to assess the performance of long-term-corrosion-damaged beam. A reinforced concrete beam corroded by 26 years of exposure to a chloride environment was tested until failure, as was a control beam of the same age. Cracking maps and corrosion maps were drawn for the corroded beam. Force displacement curves for both beams and load-displacement curves for the steel bars were also plotted. From the results it appears that corrosion has a significant impact on the load carrying capacity, stiffness and deflection of beams. The residual properties of the beam are also compared with two corroded beams previously tested at other terms: 14 years and 23 years.
