Damping wall with pressure-bearing and sliding features

Abstract

The invention relates to a damping wall with pressure-bearing and sliding features. The damping wall with the pressure-bearing and sliding features is installed on a base of mechanical equipment, on a supporting seat of a steel truss girder and between an upper floor beam and a lower floor beam of a building. The damping wall comprises an inner shear plate assembly, a lower damping groove assembly and a sliding friction assembly; the sliding friction assembly comprises sliding friction structures and positioning sliding friction structures, wherein the sliding friction structures are located between the inner shear plate assembly and the lower damping groove assembly; the shear plate assembly comprises inner shearing damping plates; the lower damping groove assembly comprises damping grooves, damping groove outer plates and a damping groove inner plate; the inner shearing damping plate is inserted into the damping grooves; viscous damping liquid is poured into each damping groove; and the positioning sliding friction structures are installed between the inner shearing damping plates and the damping groove outer plates and between the inner shearing damping plates and the damping groove inner plate. The damping wall provided by the invention provides damping, and meanwhile, a main body of the damping wall can bear the dead weight of the structure and a certain vertical load, and when relative sliding occurs, friction coefficient of a pressure-bearing plane is small.

Description

technical field [0001] The invention belongs to the aspects of civil engineering and shock absorption (vibration) of mechanical equipment, in particular to a damping wall with pressure-bearing sliding characteristics. Background technique [0002] Passive control does not require the input of external energy, and relies on the installation of shock-absorbing devices such as isolation supports and dampers in the structure to isolate or dissipate the input of seismic energy and achieve a control method that reduces the seismic response of the structure. Due to its simplicity and reliability , Practical features are widely used in practical engineering. Viscous damping wall is one of the new types of shock-absorbing and energy-dissipating devices, which were first proposed by Japanese scholars. The viscous liquid is mainly sheared by the relative displacement between the steel plates, and consumed by the internal friction force generated when the material flows. energy, thereb...
