Hybrid reinforced concrete sections combining steel and GFRP enhance ductility and energy dissipation compared to GFRP-only reinforcement. The brittle nature of GFRP necessitates a hybrid design with an outer GFRP layer for durability and an inner steel core for ductility. This study evaluates an external beam-column joint in a seismic zone, adapting current design codes to account for hybrid sections. Results confirm that hybrid joints can meet seismic design requirements, improving both durability and resilience, thus supporting the adoption of hybrid reinforcement in seismic regions.

Abstract
Hybrid reinforced concrete sections combining steel and GFRP enhance ductility and energy dissipation compared to GFRP-only reinforcement. The brittle nature of GFRP necessitates a hybrid design with an outer GFRP layer for durability and an inner steel core for ductility. This study evaluates an external beam-column joint in a seismic zone, adapting current design codes to account for hybrid sections. Results confirm that hybrid joints can meet seismic design requirements, improving both durability and resilience, thus supporting the adoption of hybrid reinforcement in seismic regions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
