The Seismic Performance of Vertical Link in Reinforced Concrete Eccentric Braced Frame (EBF) with GGBFS as Partial Cement Replacement

Vertical link Eccentrically Braced Frames (EBF) effectively absorb earthquake energy with high ductility through shear-bending mechanisms. Using reinforced concrete as a homogeneous material for bracing offers excellent elastic-inelastic behavior and stable seismic performance, preventing premature collapse. To enhance structural behavior, this study investigates using Ground Granulated Blast Furnace Slag (GGBFS) as a partial substitute for OPC. GGBFS improves concrete by reducing porosity and providing an environmentally friendly material. Cyclic load tests on CBF and EBF specimens with vertical link beams show that EBF-V-15 combines high load capacity with ductility, with GGBFS improving seismic performance and crack patterns.
