Abstract
En 中文
• Ribbed steel rebars increased capacity but reduced deformation capacity. • More fasteners shifted failure from ductile yielding to brittle fracture. • Rebars improved capacity through friction and confinement effects. • Eurocode-based models predicted smooth dowels more accurately. • Numerical simulations linked rebar friction to row-shear failure.
