In order to clarify the influence of corrosion of hot-dip galvanized steel on the structural performance for R/C beam, after corrosion promotion by the galvanostatic corrosion test was carried out, pull-out test for simple specimen and structural loading test for R/C beam were conducted. As a result, it was found that when the normal state, adhesion performance similar to that of the ordinary steel, when the corrosion occurred, the adhesion performance was improved. However, there is a possibility of cracking of the concrete due to corrosion of the plating layer, and in this case, the proof stress decreases.
