Structural performance of RC beams under simultaneous loading and reinforcement corrosion

► Simultaneous loading and corrosion cause a beam to exceed its limiting deflection. ► Simultaneous loading and corrosion impair beam strength and ductility more greatly. ► Local corrosion of tensile bar decreases beam strength and ductility more rapidly. ► Corroded beams under service loads collapse in a less ductile or even brittle way.
