| Abstract: | This paper presents results and discussions on an experimental study conducted to relate the influence of external conditions, such as the corrosion rate, the conduction time and the level of sustained load,on the mechanical properties of the corrosive beams under stress states that corroded by electrolyte accelerated corrosion test method. The strain for the cross section and the cracking development of corroded beams in the process of reinforcement corrosion are analyzed to provide a reference for further study of reinforced concrete beams supporting varied loads. |
