摘要：In reality, corrosion products expand and fill not only spaces and pores around steel bar but also micro cracks which are caused by its expansion. This paper attempted to simulate its expansion and penetration into concrete based on elastic expansion model. The apparent strain of corrosion expansion as a function of amount of corroded steel bar was utilized to consider penetration of corrosion product into concrete. Corrosion crack width was calculated based on this function. Experimental work was carried out to validate an apparent expansion model of corrosion expansion. Furthermore, appearance of the first crack and development of crack width on the surface of concrete cover were compared to result of experimental work. The results showed that corrosion crack width calculated using the apparent expansion model had a good correlation with experimental result both in RC and PC members.
