Abstract

The invention discloses an assembled shear type damper capable of achieving vertical constraint release. The assembled shear type damper comprises a damper upper steel plate (1) and a damper lower steel plate (2), wherein the damper upper steel plate (1) comprises an upper steel plate flange plate (101) and an upper steel plate web plate (102) which are connected; the damper lower steel plate (2) comprises a lower steel plate connecting web plate (201), an energy consumption web plate (202) and a lower steel plate flange plate (203) which are connected in sequence, and the upper steel plate web plate (102) is connected with the lower steel plate connecting web plate (201). According to the assembled shear type damper capable of achieving vertical constraint release, the damper releases vertical constraint, so that the force transmission path of the structure is clear, the stress state of each component is clear, and on one hand, the damping force-deformation requirement of the damper is conveniently determined and serves as the design basis of the size parameters of the damper; on the other hand, the damper cannot generate obvious vertical load and bending moment in the working process, unnecessary energy consumption reserve loss of the damper can be reduced, the damping energy consumption effect is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to an assembled shear damper for vertical restraint release, which belongs to the technical field of building structures. Background technique [0002] Shear dampers have the advantages of high strength, high stiffness, plump hysteresis curves, and superior energy dissipation capacity, and are widely used in energy-dissipating and shock-absorbing building structures. [0003] Commonly used shear dampers have certain stiffness in the horizontal shear direction and vertical direction, which not only provide additional stiffness for the structure under horizontal earthquake action but also yield energy dissipation, when the vertical deflection of the structural beam connected to it is due to the use of When the magnitude and distribution of the vertical load change during the process, the damper will also coordinate the deformation of the main structure through the deformation of the energy-dissipating parts. On the one hand, this i...
