摘要

This study conducts a detailed bibliometric and thematic analysis of global research on the behavior of corroded reinforced concrete (RC) slab–column connections under seismic and cyclic loading. Data were extracted from the Scopus database (2014–June 2025) using a structured Boolean search and refined through the PRISMA screening approach, yielding 1,021 relevant English-language publications. Bibliometric mapping using VOSviewer identified the most influential countries, institutions, authors, and journals, along with major collaboration and citation networks. The results reveal a consistent growth in research output, particularly after 2020, with China, the United States, and Italy emerging as global leaders. Keyword co-occurrence analysis classified research themes into corrosion mechanisms, seismic performance, experimental studies, retrofitting techniques, and numerical modeling. The Construction and Building Materials and Journal of Building Engineering journals were identified as the most active publication venues. A complementary qualitative review highlighted the detrimental effects of corrosion on bond degradation, punching shear resistance, and hysteretic energy dissipation. Despite significant advancements, gaps remain in modeling non-uniform corrosion, biaxial cyclic response, and the integration of artificial intelligence (AI) for predictive analysis. Overall, the study provides valuable insights into global trends and emerging directions in structural corrosion research.
