When calculating the structural damage or hysteresis curve,the relationship between internal force and deformation should be known at first.But it is difficult and trivial to calculate that during the elastoplastic phase.The numerical method is introduced,then the relationship is established considering cumulative damage.The propose method has clarity and simple formula,and it is easy to apply.
