Abstract

Reinforced concrete cable channels are highly susceptible to corrosion in underground environments, resulting in wall thinning. To explore the impact of corrosion-induced thinning on the residual load-bearing capacity of rectangular reinforced concrete cable channels, a Three-Point Bending (TEB) load-bearing capacity calculation model for rectangular reinforced concrete cable channels is proposed in this paper. The study contrasts corrosion depth with the protective layer thickness and establishes theoretical models for the residual load-bearing capacity of rectangular reinforced concrete cable channels with various corrosion depth defects. Subsequently, based on specific engineering cases, the paper calculates the load-bearing capacity of rectangular reinforced concrete cable channels with corrosion defects and validates the results through numerical simulations using ABAQUS. The findings demonstrate the feasibility of the proposed load-bearing capacity calculation model for rectangular reinforced concrete cable channels with corrosion defects.
