Abstract

The invention discloses a supporting type staged friction damper, and relates to the technical field of vibration control building dampers. The supporting type staged friction damper comprises a cross-shaped steel plate and L-shaped steel plates, first groove-shaped holes are formed in one sides of four wing plates of the cross-shaped steel plate, and second groove-shaped holes are formed in the other sides of the four wing plates of the cross-shaped steel plate; the four groups of L-shaped steel plates are connected with the cross-shaped steel plate in a matched mode in the mode that corners face the axis of the cross-shaped steel plate; each group of L-shaped steel plates comprises a first L-shaped steel plate and a second L-shaped steel plate; round holes are formed in the first L-shaped steel plate and the second L-shaped steel plate, high-strength bolts penetrate through the groove-shaped holes and the round holes matched with the groove-shaped holes, and the L-shaped steel plates are fixed to the cross-shaped steel plate; and friction elements are arranged on the attaching faces of the cross-shaped steel plate and the L-shaped steel plates. According to the supporting type staged friction damper, friction damping force can be provided by a plurality of friction surfaces, the energy consumption efficiency is higher, the assembly efficiency is high, the machining feasibility is high, and graded energy consumption is achieved.

Description

technical field [0001] The invention relates to the technical field of vibration control dampers for buildings, in particular to a support type friction damper in stages. Background technique [0002] Energy dissipation and shock absorption technology is an important means to improve the seismic performance of building structures. This technology is to install energy dissipation devices in certain parts of the structure. Before the main body enters the inelastic state, the device or component first enters the energy consumption working state. Generate friction, bending elastic-plastic or bending viscoelastic hysteretic deformation to dissipate energy or absorb earthquake or wind shock energy to reduce the vibration response of the main structure. The mainstream energy-dissipating shock-absorbing devices are divided into three categories: displacement dampers, velocity-dependent dampers and composite dampers. Among them, displacement dampers mainly include metal yield damper...
