Computer simulation of corrosion fatigue of reinforced concrete beams in marine environment.

摘要

The effect of corrosion on the fatigue life of reinforced concrete beams is studied. Two analytical models are developed to study the chloride diffusion in concrete and the percent reduction in fatigue lives in seawater as compared to air. An initial stress equivalent to the tensile strength of concrete is induced in the rebar to simulate the corrosive nature of marine environment. The analytical values are compared with the available experimental data.
