| 要旨 | Durability in harsh environments, which is controlled by the phenomena of mass transport within concrete (such as chlorides, acids etc.), has been identified as one of the major parameters controlling the long-term performance of concrete structures. Mechanical loading, which usually leads to creation of new cracks and/or extension and widening of existing ones, induces a higher penetration of chemicals. Beyond a certain concentration threshold around rebar, corrosion occurs and the load bearing capacity of a structural member may be reduced. This paper present a method for modeling the long-term performance of RC beam subjected to the simultaneous action of external loading and a chloride laden environment. The effect of cracking on the penetration of chloride ions was studied. |
