Exposed column foot component for steel frame structure

Abstract

According to the exposed column foot component for the steel structure, the energy dissipation assembly is fixedly arranged on the side face of the column body, the energy dissipation assembly is movably connected with the column body and the supporting piece, the column body pivots on the connecting piece along with swinging of the column body during an earthquake, the additional rotation freedom degree is introduced for the column body, the column body can complete self-resetting through the self weight, and therefore the energy dissipation effect is improved. The earthquake energy is dissipated through plastic deformation of the energy dissipation assembly, the energy dissipation assembly and the column jointly complete bending moment resistance, the reusability of the steel structure is improved, only the energy dissipation part damaged due to plastic deformation needs to be replaced after the earthquake, and the energy dissipation assembly and the column can be used for replacing the energy dissipation part damaged due to plastic deformation. The column foot component is simple in structure and easy to install, and construction and maintenance cost is effectively reduced.
