| Abstract: | The paper carries out numerical simulation analysis on the bearing performance of steel-tube concrete column on the both sides under horizontal impact load,and analyzes the stress,stress time-history curve,and formation and changing process of plastic hinge of important structural parts.Results show that: the fixed steel-tube concrete on both sides has great plastic deformation capacity and better impact-resisting mechanical performance under horizontal impact load. |
