Viscous liquid damping torsion-resistant cylinder used in building structure

Abstract

The invention relates to a viscous liquid damping torsion-resistant cylinder used in a building structure. The viscous liquid damping torsion-resistant cylinder comprises two cover plates, an outer cylinder body (3), an inner cylinder body (4) and damping materials (7). The inner cylinder body (4) is sleeved with the outer cylinder body (3). One end of the inner cylinder body (4) is fixedly connected with one cover plate. One end of the outer cylinder body (3) is fixedly connected with the other cover plate. A sealed cavity is defined by the two cover plates, the outer cylinder body (3) and the inner cylinder body (4), and the viscous liquid damping materials are injected into the cavity. Two or more stiffening ribs (6) are arranged between the inner cylinder body (4) and the outer cylinder body (3). At least one stiffening rib (6) is fixedly connected with the outer cylinder body (3), and at least one stiffening rib (6) is fixedly connected with the inner cylinder body (3). By the adoption of the viscous liquid damping torsion-resistant cylinder, the problems that according to an existing damper, the durability is poor, residual deformation exists, the energy dissipation capacity is insufficient, and the damping capacity is simplex are solved.

Description

technical field [0001] The invention relates to the field of civil engineering construction, in particular to a viscous fluid damping anti-torsion cylinder used in building construction for torsional vibration control of building construction. Background technique [0002] When an earthquake or wind acts on a structure, the structure absorbs a large amount of external energy, which causes horizontal vibration and torsional vibration of the structure. The commonly used method for traditional structures to resist earthquakes is to enhance the structural stiffness and deformation capacity. When encountering strong earthquakes, the energy dissipation of the structure needs to rely on the elastic-plastic deformation of the components. The plastic deformation of the components continues to accumulate, which inevitably gives damage to structural members. The traditional method with "resistance" as the main approach needs to increase the cross-section of the components to increase ...
