Damper with assembled structure

Abstract

The invention discloses a damper with an assembled structure. The damper comprises a first clamping plate module, a second clamping plate module, a damping bar module and a pin module, the first clamping plate module comprises a first connecting plate and a plurality of first clamping plates, the first clamping plates are fixed on one side of the first connecting plate at intervals, the other side of the first connecting plate is used for fixedly connecting with a beam structure, the second clamping plate module comprises a second connecting plate and a plurality of second clamping plates, the second clamping plates are fixed on one side of the second connecting plate at intervals, the other side of the second connecting plate is used for fixedly connecting with a column or a wall, the damping bar module is fixed on the first clamping plates and the second clamping plates in a penetrating manner, the pin module is fixed on the first clamping plates and the second clamping plates in a penetrating manner, and at least one first clamping plate is fixed between two adjacent second clamping plates. The damper with the assembled structure is small in volume, cost is saved, elastic rigid connection of joints under small seism can be ensured, plastic varying rigid connection of the joints under large seism can be ensured, energy consumption actions of the damper are achieved, seismic force applied to the structure is decreased, and safety of the main structure is protected.

Description

technical field [0001] The invention relates to a damper, in particular to a damper with an assembled structure. Background technique [0002] Compared with cast-in-place concrete structures, prefabricated concrete structures have relatively weaker integrity and complex node structures. At the same time, the seismic performance of prefabricated concrete structures has drawn close attention from the engineering and academic circles. Existing studies have shown that the failure characteristics of prefabricated concrete structures under earthquakes are mainly manifested in the discreteness and collapse of the overall structure due to the failure of the connections between components, while the prefabricated components themselves are less damaged. In the past, research on the seismic performance of prefabricated concrete structures at home and abroad mainly focused on the joints of the components, and there were relatively few studies on the overall seismic performance of the s...
