Study on Deterioration of Structural Performance of Corroded Reinforced Concrete Beam

摘要

The study on the deterioration of structural performance of corroded reinforced concrete beam possesses the important meaningful for the safety of reinforced concrete beam. In this paper, loading experiment on seven reinforced concrete model beams which longitudinal reinforcement corrosion rates are from 0% to 15% based on electrochemical accelerated corrosion is introduced. Through the analysis of the experiment results, the effect of different longitudinal reinforcement corrosion rate on mechanical performance of reinforced concrete beam is studied. At the same time, the coordination coefficient k_s used in theory calculation is evaluated. Some valuable results are acquired and are provided significant reference for design of reinforced concrete beam.
