A three-dimensional metal energy dissipation damper

Abstract

The invention relates to a three-dimensional metal energy dissipation damper, which comprises an upper connecting plate, a lower connecting plate, U-shaped steel and S-shaped steel, a lateral connecting support column and a central rectangular connecting column; two straight sections of the U-shaped steel are respectively connected with the upper connecting plate and the The lower connecting plate is connected as a whole, the upper end of the central rectangular connecting column is fixedly connected with the upper connecting plate, and the lower end is suspended in the air; the outer surface of the straight section at one end of the S-shaped steel is fixedly connected with the outer surface of the central rectangular connecting column, and the other end is connected with the lateral connecting support column. Overall; the lower end of the lateral connection support column is fixedly connected to the lower connection plate; S-shaped steel is symmetrically arranged around the central rectangular connection column. The invention adopts U-shaped steel and S-shaped steel with special shapes as energy-dissipating elements. When the upper and lower ends are subjected to shear force and bending moment, the bending deformation and torsional deformation generated by U-shaped steel and S-shaped steel can be used within a limited height to obtain larger The amount of deformation, the hysteresis curve is full, and the energy dissipation capacity is large, which can effectively avoid steel fracture and effectively improve the seismic performance of the building structure.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction of civil engineering structures, and in particular relates to a novel three-dimensional metal energy-dissipating damper, which is suitable for vibration reduction of industrial and civil buildings, bridges, water conservancy and important equipment and other projects. Background technique [0002] my country is located in the affected areas of two strong earthquake-prone areas, the circum-Pacific seismic belt and the Eurasian seismic belt, and is a country with frequent earthquakes. How to improve the seismic performance of buildings, bridges, water conservancy, etc. is a problem that engineering design attaches great importance to. In the field of anti-seismic technology of building engineering structures, the easier and more effective vibration reduction method is to add dampers to the structure. At present, the common types of dampers at home and abroad mainly include viscous dampe...

AI Technical Summary

Problems solved by technology

[0005] In terms of three-dimensional vibration reduction and energy consumption, there have been related researches in China on the use of rigid masses, elastic layers, springs, and viscoelastic damping units to achieve three-dimensional vibration reduction and energy consumption. The structure makes the three-dimensional vibration damper bulky, inconvenient to install, and expensive. It is mainly used in large-scale industrial facilities for vibration reduction and energy consumption, and it is difficult to promote and use in the field of engineering structures.

At present, the research on three-dimensional dampers is still in the theoretical and experimental stage, and lacks practical engineering applications.
