Abstract

The invention discloses a damping pipeline system based on friction energy dissipation and belongs to the technical field of structure damping engineering. The damping pipeline system comprises a pipeline, an inner pipe clamp, a friction energy dissipation layer, an outer pipe clamp and damping supports. The inner pipe clamp is fixed to the pipeline through bolts. The friction energy dissipation layer is arranged between the inner pipe clamp and the outer pipe clamp. The pipeline system is fixed to a structural element through the damping supports. Under an earthquake load, the damping supports provide supporting rigidity for the pipeline system, a friction energy dissipation material serves as the damping energy dissipation layer of the pipeline system and dissipates input earthquake energy, the earthquake acceleration of the pipeline system is decreased, and earthquake internal force of the pipeline system is reduced. The damping pipeline system is simple in structure, convenient touse, low in cost, remarkable in damping effect, and capable of reducing the earthquake internal force of the pipeline system as well as isolating influences of power pipeline vibration on the structural element.

Description

technical field [0001] The invention belongs to the technical field of structure damping (vibration) engineering, and relates to a pipeline damping technology, in particular to a damping pipeline system based on frictional energy consumption. Background technique [0002] Piping system is a common non-structural component of building structures, including electromechanical pipes, ventilation pipes, water supply pipes, etc., which make an important contribution to the use function of the structure. During an earthquake, piping systems are more susceptible to failure than structural members. Its destruction will not only cause huge direct economic losses, but also cause serious secondary disasters and loss of building functions. How to effectively reduce the structural damage of the pipeline system caused by earthquakes and reduce the losses caused by disasters has become one of the key issues in the development of pipeline system technology. [0003] The friction damper exe...
