摘要: Abstract This paper presents the results of an experimental campaign carried on exterior beam-column joints made with recycled concrete, containing Electric Arc Furnace (EAF) slag as full replacement coarse natural aggregates. Three real-scale joints, one a conventional mix and two EAF were tested under horizontal reversed cyclic loading, applied in quasi-static conditions. The three exhibited same failure mode, which involved shear panel joint yielding beams steel bars. mode is indeed mainly influenced by concrete strength was chosen to better highlight influence use. Similar hysteresis response, stiffness decay, dissipated energy ductility obtained both joints. Results demonstrate that specimens are able attain higher loads than specimen at imposed displacement, less damaged.
