A self-resetting shock-absorbing anti-collapse structure for frame structures

Abstract

The invention discloses a self-reset shock-absorption and anti-collapse structure for a frame structure, and belongs to the technical field of building. According to the self-reset shock-absorption and anti-collapse structure, the problem that energy-dissipation, shock-absorption and continuous collapse resistance of the frame structure cannot be achieved simultaneously in the prior art is solved.The self-reset shock-absorption and anti-collapse structure is arranged in an enclosed area of two beams and two columns of the frame structure, a sliding support seat is fixedly connected with the upper beam, a long hole is horizontally formed in the sliding support seat, the lower ends of two metal columns are correspondingly hinged to the lower beam, the upper parts of the two metal columns are correspondingly and slidably connected with the sliding support seat through the long hole, an SMA wire is correspondingly wound around the top end of each metal column, the two ends of each SMA wire are correspondingly located on the two sides of the metal column which is wound with the SMA wire, and are correspondingly and fixedly connected with the lower beam. Energy dissipation, self-reset and continuous collapse resistance are designed comprehensively, the damage of the frame structure under the earthquake effect is reduced, a supporting effect is achieved in the local failure of the frame structure, and the collapse and damage of the overall structure is avoided.

Description

technical field [0001] The invention relates to a self-resetting shock-absorbing anti-collapse structure for frame structures, which belongs to the technical field of buildings. Background technique [0002] my country is a country with frequent earthquakes. Based on the existing scientific and technological level and economic conditions, we have proposed "three levels" of fortification goals for buildings against earthquakes, that is, "not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes." . On the basis of the three-level fortification, the building structure is comprehensively designed by adopting the concepts of energy dissipation, shock absorption, progressive collapse resistance, and seismic toughness, so that it can meet different seismic performance requirements. Energy dissipation and shock absorption refers to the addition of energy dissipation devices in the main structure to jointly resist the earthquake, th...
