It was anempt ∈d to pr 。sent a method to quantitatively evaluate darnages to RfC shear columns subjected to earthq ロake IQads in the post − peak region inciuding conapse . The method that uses the post − peak load − deflectioll relations fbrmulated based on test results and assumes the concept of the fail 肛 e surface contraction following shear failure , enables us to compute how rnuch residual lateral −and vertical −load c 蜘 g capacities of colurnns are when they undergo a given level of
