| Research Abstract |
The purpose of this study is to evaluate the deterioration progress(propagation stage, acceleration stage, deterioration stage) and the load bearing capacity of RC member in cold climate. In this study, it is confirmed that the influence of freezing and thawing action on chloride penetration into concrete. The degradation curve of flexural capacity for RC member under composite deterioration as frost attack and steel corrosion induced by chloride attack is indicated with experimental studies.
