A friction energy dissipation device and a self-resetting friction ductility split column

Abstract

The present invention provides a frictional energy dissipation device and a self-resetting frictional ductility split column, comprising an energy dissipation shell, and an elastic reset structure and a sliding shaft arranged inside it; the elastic reset structure is arranged on the energy dissipation shell Among them, rubber is filled between the elastic reset structure and the energy dissipation shell, and the sliding shaft is horizontally arranged in the elastic reset structure, and can slide in the elastic reset structure. The friction energy dissipation device increases the split ductility, improves the lateral deformation capacity of the column, can dissipate the seismic energy in time, avoids the shear damage of the column, and increases the safety of the column in the underground space. After that, it can reset itself and has a long service life. The invention has good shock absorption effect, clear principle, simple design, easy production and installation, feasible post-maintenance and convenient operation, and can be popularized and applied in underground structural engineering.

Description

technical field [0001] The invention relates to the field of structural engineering construction, in particular to a frictional energy-dissipating device and a self-resetting frictional ductile split column, which belongs to the field of anti-seismic technology of prefabricated load-bearing columns. Background technique [0002] In recent years, with the continuous development of the economy and the continuous deepening of the urbanization process, the development of underground space and the construction of high-rise buildings have become important research topics in urban planning. Reasonable urban planning and the promotion of the development of underground space and high-rise buildings are of great benefit to alleviating urban traffic pressure, improving the utilization rate of land resources, and innovating urban development models. [0003] In these structures, it is inevitable that there will be columns bearing large axial loads. At present, the widely used columns ar...

Problems solved by technology

[0004] Aiming at the problem that the split column in the existing structure cannot quickly dissipate the impact caused by the earthquake vibration and is prone to column damage, the present invention provides a friction energy dissipation device and a self-resetting friction ductile split column. The device can greatly improve the vertical compressive capacity and horizontal shearing capacity of the column during earthquakes, avoid brittle failure of short columns, and at the same time ensure the integrity of the column under normal use conditions
