Seismic response of resilient EBFs equipped with innovative reversible short links

Minimising structural and non‐structural damage is crucial for reducing repair costs and ensuring rapid restoration of building functionality after a destructive seismic event. One effective strategy is the use of repairable dissipative devices. The present study preliminarily investigates the seismic performance of resilient steel Eccentrically Braced Frames (EBFs) equipped with reversible damage‐free seismic link (RDF‐Link). The proposed system integrates friction devices to dissipate energy and is connected to external beams via bolted joints, enabling replacement and repair without affecting the primary structure. A 4‐storey buildings has been designed per Eurocode 8 and modelled in OpenSees. Incremental Dynamic Analyses (IDA) are performed using 30 ground motion records. The seismic performance of EBFs with conventional links (C‐EBF) and RDF‐Link (RDF‐EBF) is investigated and compared.
