Self-resetting energy dissipating steel column base joint

Abstract

The invention provides a self-resetting energy dissipating steel column base joint. The column base joint includes a steel column, yield energy dissipating bodies, a self-resetting system and a concrete foundation beam. A prestressed rib connection plate is welded on the steel column. Oppositely-penetrating connection holes I are formed in the surface of the prestressed rib connection plate. A steel plate is buried on the top of the concrete foundation beam. Several steel casings are embedded in a beam body of the concrete foundation beam. Oppositely-penetrating connection holes II are formedin the positions, corresponding to the steel casings, of the steel plate on the top of the foundation beam. Prestressed ribs are anchored at the top of the prestressed rib connection plate and the bottom of the concrete foundation beam. The peripheral walls of the four sides of the steel column are each provided with one yield energy dissipating body. The column base joint can effectively reduce or even eliminate the problem of column base damage under the earthquake action. Self-resetting is achieved by prestressed wires, the residual deformation of the structure is effectively reduced, the self-resetting ability is high, and the energy dissipating bodies can also be replaced.

Description

Technical field [0001] The invention relates to the technical field of structural engineering, in particular to a self-resetting energy dissipation steel column foot node. Background technique [0002] Traditional structures dissipate energy through plastic deformation of components during an earthquake, which will cause irreversible residual deformation of the structure. After the earthquake, the performance of the structure is severely affected and cannot be used. Finally, it has to be dismantled, causing huge economic losses. Summary of the invention [0003] The purpose of the present invention is to provide a self-resetting energy-dissipating steel column foot joint to solve the problems existing in the prior art. [0004] The technical solution adopted to achieve the purpose of the present invention is as follows: a self-resetting energy dissipating steel column foot joint includes a steel column, a yielding energy dissipator, a self-resetting system and a concrete foundation ...

Problems solved by technology

[0002] Traditional structures dissipate energy through the plastic deformation of components during earthquakes, which will cause unrecoverable residual deformation of the structure. After the earthquake, the performance of the structure is seriously affected and cannot be used. Finally, it has to be demolished, causing huge economic losses.
