One of the key-elements in Structural Health Monitoring of reinforced concrete structures is the level of rebar corrosion and the way in which it affects the structural performance. A dynamic four-point-bending test was developed to help understanding the deflections of concrete structures under corrod-ed conditions. With this test, two equivalent beams are loaded under equal conditions. To generate corrosion, one beam was exposed to a chloride-water solution. The other beam was exposed to tap water only, in order to act as a reference. This paper reports and discusses seven weeks of experi-mental data, including deflections and crack widths. Although there was not yet a significant effect of corrosion, some changes in crack widths and in deflections were observed. Furthermore, the influence of temperature and surface wetting exposure on the structural behaviour will be discussed.
