Corrosion-induced degradation in reinforced concrete (RC) structures, which is initiated within the first few decades of their lifespan, significantly challenges their seismic resilience and resistance.
While existing research tools can assess performance, they fall short in predicting changes in seismic resistance resulting from alterations in the core properties of RC structures.
To bridge this gap, we introduce a numerical seismic resistance prediction method (SRPM), specifically designed to predict changes in seismic resistance of structures, including those reinforced with carbon fiber-reinforced polymer (CFRP), known for its non-corrosive properties.
We use this tool to analyze steel-reinforced and carbon fibre-reinforced polymer concrete (CRC) structures.
This study reveals distinct differences in the long-term seismic resistance of these structures.
The resistance capacity factor (RCF) of RC structures rapidly decreases over time, while the reduction in RCF for CFRP-reinforced structures is about half that of RC structures.
