In practical engineering, the effect of corrosion on the shear carrying capacity of reinforced concrete simply supported beams is relatively common. Therefore, this paper focuses on the shear carrying capacity of corroded reinforced concrete simply supported beams.Firstly, this paper will introduce the traditional theoretical calculation methods and experimental testing methods, explore their applicability, limitations, advantages and disadvantages for calculating the shear carrying capacity of corroded reinforced concrete simply supported beams. Subsequently, ANSYS software will be used for numerical simulation analysis to explore the differences between simulation results and experimental results and their causes. Finally, by comparing and analyzing multiple sets of experimental data, this paper will draw conclusions and recommendations about the relationship between the degree of corrosion and load-bearing capacity.精品文档---下载后可任意编辑Through this research, it is expected to gain a deep understanding of the calculation method and accuracy of the shear carrying capacity of corroded reinforced concrete simply supported beams, and to provide theoretical guidance and technical support for related engineering practices.Keywords: reinforced concrete; corrosion; simply supported beam; shear carrying capacity; numerical simulation
