Embodiment 1

[0045] When the present invention adopts the middle column type to be installed in the building structure, such as Figure 9 As shown, several shear-bending combined staged yield mild steel dampers are combined and installed in the main structure of the building. The top horizontal plane of the L-shaped side steel plate 1 on the upper part of the combined shear-bending mild steel damper is connected to the upper main beam of the floor through high-strength bolts, and the bottom horizontal plane of the lower L-shaped side steel plate 1 is connected to the lower part of the floor through high-strength bolts. The wall support is fixedly connected. When an earthquake occurs, a relative displacement occurs between the two L-shaped side steel plates 1 in each damper. Under small earthquakes, the yield displacement of the rectangular soft steel energy-dissipating steel plate 4 is small, and the rectangular soft steel plate 4 has a small displacement. The steel energy-dissipating ste...

Embodiment 2

[0047] When the present invention adopts supporting type to be installed in the building structure, such as Figure 10 As shown, several shear-bending combined staged yield mild steel dampers are combined and installed in the main structure of the building. The top horizontal plane of the L-shaped side steel plate 1 on the upper part of the combined shear-bending mild steel damper is connected to the upper main beam of the floor through high-strength bolts, and the bottom horizontal plane of the lower L-shaped side steel plate 1 is connected to the main beam of the lower floor through high-strength bolts. The herringbone steel supports set on the beams are fixedly connected, and the supports act as fixed dampers. When an earthquake occurs, a relative displacement occurs between the two L-shaped side steel plates 1 in each damper. Under small earthquakes, the yield displacement of the rectangular soft steel energy-dissipating steel plate 4 is small, and the rectangular soft ste...

Abstract

The invention discloses a shear yield and bending yield combined type staged soft steel damper. The damper comprises two L-shaped side steel plates (1) which are arranged symmetrically around an original point; the two ends of each of X-shaped soft steel energy-consuming steel sheets (2) are vertically welded and connected with two parallel X-shaped soft steel energy-consuming sheet connecting plates (3) to form an X-shaped steel sheet energy-consuming component (7); the rib wall of a rectangular soft steel energy-consuming steel sheet (4) is vertically welded and connected with rectangular steel sheet reinforced plates (6), and the upper and lower ends of the rectangular soft steel energy-consuming steel sheet (4) are vertically welded and connected with two parallel rectangular steel sheet connecting plates (5) to form a rectangular steel sheet energy-consuming component (8); and the X-shaped steel sheet energy-consuming component (7) and the rectangular steel sheet energy-consuming component (8) are arranged side by side in a cavity formed by the L-shaped side steel plates (1) and are fixedly connected with the vertical surfaces of the L-shaped side steel plates (1) through high-strength bolts, respectively. The shear yield and bending yield combined type staged soft steel damper is simple in structure, strong in energy-consuming capacity, good in staged energy-consuming effect and wide in application scope.

Description

technical field [0001] The invention relates to the field of anti-seismic and shock-absorbing civil engineering, in particular to a metal energy-dissipating damper in a structure passive shock-absorbing control system, specifically a shear bending device that can provide an additional damping ratio for a building structure and reduce the seismic response of a structure Combined staged yield mild steel damper. Background technique [0002] The metal energy dissipation damper uses the metal material to enter the plastic range and then hysteresis energy dissipation. Metal materials such as mild steel, lead, and shape-memory metals are widely used to manufacture various types of dampers due to their good ductility and hysteresis capabilities. From the force form, it can be divided into axial yield type, shear yield type, bending yield type and torsional yield type damper. At present, the most widely used and representative damper products are: X-shaped and triangular dampers,...
