Frame beam and column connecting joint comprising replaceable energy dissipation part

Abstract

The invention discloses a frame beam and column connecting joint comprising a replaceable energy dissipation part. The frame beam and column connecting joint comprises a frame column, a frame beam, the energy dissipation part and a restraining plate,wherein the frame beam includes a beam body section, a wing plate and a web plate; the energy dissipation part comprises an energy dissipation plate and a connecting lug plate, the energy dissipation plate includes an energy dissipation section, a column side connecting section and a beam side connecting section, wherein the column side connectingsection and the beam side connecting section are arranged at both ends of the energy dissipation section, the yield forces of the column side connecting section and the beam side connecting section are both greater than that of the energy dissipation section, the column side connecting section is detachably and fixedly connected with the frame column, the beam side connecting section is detachablyand fixedly connected with the frame beam, and the web plate is detachably connected with the connecting lug plate in a hinged mode; the restraining plate and the wing plate are correspondingly and fixedly arranged on both sides of the energy dissipation plate so as to limit sided displacement of the energy dissipation section, and gaps are arranged between the restraining plate and the energy dissipation section as well as between the wing plate and the energy dissipation section. According to the frame beam and column connecting joint, the ductility and energy dissipation capacity are high,the seismic performance is good, and the restoration efficiency is high after an earthquake, and the repairing cost is low.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a frame beam-column connection node with replaceable energy-consuming parts. Background technique [0002] Earthquake is one of the major natural disasters in human history, which has brought huge casualties and economic losses to human society. If the post-earthquake repair countermeasures are not considered in the design, it may be difficult to repair or the repair time will be very long, which will seriously affect the emergency and normal use after the disaster. How to design a recoverable functional structure, component or connection node, which can restore its normal function as soon as possible after an earthquake has become one of the important research directions for sustainable development of engineering structure earthquake resistance. [0003] In the Northridge earthquake in 1994 and the Kobe earthquake in 1995, a large number of beam-column rigid joints such as full...

Problems solved by technology

However, the fully bolted assembly joints in the related art mainly dissipate the seismic energy through the slippage of the contact surface between the bolted components, and the improvement in ductility and energy dissipation capacity is very limited.
