Sažetak
In this work an experimental research will be presented in which reinforced concrete specimens were exposed to accelerated corrosion and tested in uniaxial tension in order to investigate the degradation of tension stiffening due to reinforcement corrosion. Before exposing the reinforced concrete specimens to accelerated corrosion in a cyclic corrosion test chamber cracks were introduced into the specimens. Testing was conducted on both corroded and controlling un-corroded specimens, and a relationship between the applied load and mean strain of the cracked specimens was established. The proposed test-setup is closer to the nature of a great number of reinforced concrete structures subjected mainly to bending, meaning that the cracks form in concrete members already at the beginning of the exploitation of the construction, i.e. well before the corrosion process has started.
