The major reason of buildings collapsing due to earthquakes is the breaking of reinforcement bars without crossing their ultimate tensile strength. The amount of seismic energy crossing the rebars is the main criteria of failure of steel reinforcement bars, and ultimately collapse of buildings. Thus, the steel reinforcement to be used in high seismic prone areas must be highly ductile, so as to absorb sudden and tremendous amount of energy without yielding.
