Abstract

The invention discloses an energy consuming device and a resetting joint. The energy consuming device comprises a body member, a limiting member, a spring, a first connecting member, a second connecting member, a first support and a second support; the first support and the second support are used for being connected with the resetting joint, the body member is a strip-shaped rod member, and connection of the energy consuming body member and the two supports is realized through bolts; and the spring and a tooth-shaped engaging structure are arranged at the connecting position of the second support and the body member. Through analog simulation, it is shown that the residual deformation of the joint is substantially zero; the energy consuming device can effectively eliminate the residual deformation; and the resetting performance and the seismic performance of the joint of the energy consuming device can reach the optimal state.

Description

technical field [0001] The invention belongs to the technical field of earthquake prevention and disaster reduction for structural buildings, and in particular relates to an energy consumption device and a self-resetting node. Background technique [0002] The self-resetting structure is a new type of structure aimed at reducing the residual deformation of the building structure after the earthquake. By introducing prestress into the structure, the maximum deformation of the structure is controlled, and the residual deformation of the structure is reduced or even eliminated, so that the building structure can quickly recover after the earthquake. Reuse. Rationally designed self-resetting structures can meet the set performance goals, so the application of self-resetting structures is one of the important ways to build a recoverable functional city. In recent years, self-resetting structures have attracted extensive attention from researchers at home and abroad. [0003] At...
