Abstract

The invention discloses an in-series disc spring large deformation energy consumption beam column node, which comprises an assembly type column, an assembly type beam and a disc spring combination type damper, wherein the disc spring combination type damper consists of an energy consumption rod, a disc spring set, an internal thread sleeve, an outer sleeve, a sliding guide rod and an extrusion nut, one end of the disc spring combination type damper is fixed on the fixed plate of a surface of the assembly type beam, and the other end passes through the flange plate of the assembly type column and presses tightly the flange plate. By adjusting the pressure of the extrusion nut, tensile deformation generated by the two ends of the disc spring combination type damper can be fully supplied by the energy consumption rod under the action of small and moderate earthquakes, the other part is supplied by the compressive deformation of the disc spring set, so that the disc spring combination typedamper has better deformability, and the fatigue performance of the disc spring combination type damper is conducive to being improved.

Description

technical field [0001] The invention relates to an energy-dissipating device, in particular to a large-deformation energy-dissipating beam-column node of series disc springs. Background technique [0002] Earthquake is a serious natural disaster, which causes heavy casualties and serious property losses. Among them, the destruction of building structures and the secondary disasters caused by fire are one of the important reasons for casualties and property losses. In this regard, people have continuously explored the seismic resistance of building structures, and proposed the concept of energy dissipation and shock absorption, aiming to effectively reduce the seismic response of structures by installing energy dissipation devices in structures to absorb and dissipate energy. , so as to avoid serious damage to the main part of the structure. The energy-dissipating rod is a mild steel damper. The core part enters into yield under the action of the earthquake, and the outer re...
