The invention discloses an in-column lifting controlled swing frame for reinforcing a steel frame structure and an assembling method thereof, a plurality of external attached swing frames are arranged on the side face of a main body steel frame, each external attached swing frame comprises two swing side columns and a plurality of transverse supports, and the transverse supports are arranged in the vertical direction to connect the two swing side columns; the swing side columns are hinged to the supporting columns on the side faces of the main body steel frame through rigid connecting pieces. Dampers are connected between the swinging side columns and the supporting columns on the side faces of the main body steel frame; and a longitudinal horizontal support is connected between the swinging side columns of the adjacent external swinging frames. Each swing side column is divided into an upper column section and a lower column section, the transverse supports are located on the upper column sections, the outer diameter of the lower column sections is larger than that of the upper column sections, the bottoms of the upper column sections are lapped at the center of the top of the lower column sections, vertical limiting plates are arranged on the top face of the lower column sections around the bottoms of the upper column sections, and the bottoms of the lower column sections are fixed to the ground through a foundation. And while the enough anti-seismic performance is achieved, the swing deformation of the structure is effectively controlled and reduced.
Description
technical field [0001] The invention belongs to the field of structural earthquake resistance, and relates to a column-lifting controlled rocking frame for reinforcing a steel frame structure and an assembling method thereof. Background technique [0002] Steel frame structures are widely used in high-rise and super high-rise buildings because of their high strength, light weight, good ductility and energy dissipation capacity. However, under the action of strong earthquake, due to the high stiffness of beam-column joints, the plastic deformation of the material is difficult to develop, and brittle failure easily occurs in beam-column welded joints. Since then, a lot of research has been done on beam-column connection joints of steel structures, the purpose is to make the plastic hinges move outward when the joint area reaches a strong earthquake, so as to avoid cracks in the joints and brittle failure. The larger the residual deformation, the larger the deformation of the ...
