Research on Residual Strength of Concrete under Fatigue Loading and Corrosion of Chloride

Article Preview

Abstract:

In the actual project, many concrete structures not only suffer the loading of static force and the repeated loading but also affected by the corrosive effects of chemical substances in external environment, which makes concrete corrosion and damage become an unavoidable issue in engineering. The research on it at home and abroad is still in stage of theoretical exploration. This paper studied the attenuation of the residual strength of concrete under fatigue loading and corrosion of chloride, using self-designed experimental corrosion fatigue loading device. The results show that the corrosion of concrete by chlorine ion is unneglected, its influence is greater than mathematical superposition of alternating load and corrosion when they affect the concrete separately.
