| 摘要： | Abstract The reinforcing steel bars embedded in the concrete of a reinforced concrete (RC) structure in a region with high airborne chloride concentrations may corrode. To avoid overestimating the seismic capacity assessment, it is necessary to understand the residual shear strength of an RC frame with infilled wall and localized corrosion. This work investigates the residual shear strength of an RC frame with infilled wall and localized corrosion by designing five wall specimens with corroded reinforcing steel bars to obtain the residual shear strength of each RC frame with infilled wall with different corrosion zones. Additionally, a model based on the softened strut-and-tie model is proposed to determine the residual shear strength of an RC frame with infilled wall and localized corrosion. The experimental and calculation results are compared to verify the application of the proposed model for the shear strength of an RC frame infilled corroded RC wall. |
