Electric-eddy-type coupling-beam damper

Abstract

The invention relates to an electric-eddy-type coupling-beam damper which is arranged between adjacent shear wall structural coupling beams. The electric-eddy-type coupling-beam damper is characterized in that the electric-eddy-type coupling-beam damper comprises a yield energy-consumption assembly and an electric-eddy energy-consumption assembly; the yield energy-consumption assembly comprises upper U-shaped soft steel and lower U-shaped soft steel which are arranged between the adjacent shear wall structural coupling beams correspondingly; and the electric-eddy energy-consumption assembly isarranged in a space formed by the upper U-shaped soft steel and the lower U-shaped soft steel. Compared with the prior art, the electric-eddy-type coupling-beam damper has the technical advantages that the self-adaption energy-consumption capacity is high, energy consumption is high, the sensitiveness is high, and design is easy, overcomes the choke point of a traditional damping technology, andis suitable for damping design of a fabricated shear wall structure in a high-seismic-intensity area.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to an eddy current type coupling beam damper. Background technique [0002] Compared with the traditional cast-in-place concrete shear wall structure, the prefabricated concrete shear wall structure has the advantages of high production efficiency, good component product quality, energy and material saving, etc. The prefabricated shear wall structure will become an indispensable part of my country's construction system part of the However, due to the fact that its overall seismic performance is worse than that of cast-in-place structures, the improvement of the seismic performance of prefabricated shear wall structures is a key scientific and technical issue that needs to be solved urgently.

However, due to the fact that its overall seismic performance is worse than that of the cast-in-place structure, the improvement of the seismic performance of the prefabricated shear wall structure is a key scientific and technical issue that needs to be solved urgently.

[0003] The seismic performance of conventional prefabricated reinforced concrete shear wall structures is poor: under the action of earthquakes, the energy is mainly consumed by the damage of the joints of structural components and the damage of structural components; unbonded post-tensioning prestressed precast concrete shear walls The structure has self-recovery center ability and good earthquake resistance under the action of earthquake, but the energy dissipation capacity of the structural system is insufficient
