Abstract
AbstractThe present research examines the structural performance of exterior beam‐column connections made with the hybrid use of fibers and stone waste in engineered cementitious composite (ECC). The polyvinyl alcohol (PVA), recron 3 s polyester (PET) and micro steel fiber (MSE) were dispersed in various ECC mixtures to analyze the impact of fiber hybridization. The stone waste (SW) was utilized in different ECC mixtures as replacement of silica sand (SS). The performance of ECC beam‐column connection specimens was judged in terms of hysteresis load–deflection behavior, energy dissipation, ductility, and cracking pattern. The recorded results of ECC reinforced specimens were compared with specimens made with normal concrete (NC). Recorded results revealed that the connections made with ECCs exhibited better performance in terms of ductility and various parameters as compared to NC connections. The hybrid dispersion of fibers and addition of SW also contributed in improving the behavior of ECC specimens. The higher deformation, loading response, energy dissipation and ductility indicated that structures made with ECC can withstand strong ground earthquake motions.
