Problems solved by technology

Outside the plane, due to the limitation of the damping wall structure, there is no reliable connection between the inner and outer steel plates, and the clear distance between the steel plates is extremely small, which cannot provide sufficient out-of-plane rigidity
In actual engineering, once the viscous damping wall is damaged outside the plane, not only the energy dissipation effect of the viscous damping in the plane cannot be guaranteed, but also the safety of the main structure will be affected.

Abstract

A structure and realization method for solving the out-of-plane stiffness of a viscous damping wall, a structure for solving the out-of-plane stiffness of a viscous damping wall includes angle steel, stiffeners, anchor bolts, polytetrafluoroethylene plates, and slider groups; a solution The out-of-plane stiffness of the viscous damping wall is realized through the sliding contact between the first slider and the second slider. Constraints limit the outward displacement of the viscous damping wall along the vertical plane direction. The out-of-plane stiffness of the viscous damping wall is guaranteed, and the movement of the viscous damping wall in the direction parallel to the surface can be realized, which improves the connection strength between the viscous damping wall and the reinforced concrete beam.

Description

technical field [0001] The invention belongs to the field of anti-seismic structural systems, and in particular relates to a construction and realization method for solving the out-of-plane stiffness of a viscous damping wall. Background technique [0002] The viscous damping wall is a kind of energy-dissipating and shock-absorbing component, which belongs to the velocity-dependent damper. It dissipates energy through the shear hysteresis of viscous materials to improve structural damping and reduce structural seismic response or wind-induced vibration. . Compared with the traditional cylindrical viscous damper, the viscous damping wall relies on the high-viscosity fluid filled in the extremely small clear distance between the steel plates to provide damping force and dissipate energy when the steel plates are staggered. The viscous fluid has a large shear area, It can provide greater damping; in addition, the structure of the viscous damping wall is simple, there is no ris...
