Abstract

The invention discloses a friction energy consumption beam-column joint for a prefabricated structure. The friction energy consumption beam-column joint for the prefabricated structure comprises an additional friction energy consumption device which is located in an area where the beam-column joint is hinged. The additional friction energy consumption device comprises a slotting driving rod I, a slotting driving rod II, a driving rod I, a driving rod II and a pre-buried steel plate I, wherein the pre-buried steel plate I is located at the position where beam-column joint is hinged; and the two sides of the pre-buried steel plate I is hinged to one ends of the slotting driving rod I and the slotting driving rod II correspondingly, the other ends of the slotting driving rod I and the slotting driving rod II is hinged to one end of the driving rod I, the other end of the driving rod I is hinged to a column through two pre-buried steel plates II, and one end of the driving rod II is hinged to a beam through two pre-buried steel plates III. The friction energy consumption beam-column joint has energy consumption ability under the effect of big earthquakes, the additional friction energy consumption device consumes energy through slidable friction and rotary friction, the energy of the earthquakes is dissipated, and structure damage is reduced; when the friction energy consumption beam-column joint is used normally, the additional friction energy consumption device provides rigidity for the joint, internal force delivery is achieved, and the hinged joint can show similar performance with a rigid joint.

Description

technical field [0001] The invention relates to the technical field of anti-seismic and shock-absorbing control of building structures, in particular to a frictional energy-dissipating beam-column joint for prefabricated structures. Background technique [0002] Due to the advantages of fast construction speed, high component quality, and environmental protection, prefabricated concrete structures have been widely used at home and abroad in recent years. However, under the action of earthquake, compared with the traditional cast-in-place concrete structure, the component connection nodes of the precast concrete structure are its weak links. The joints of prefabricated structures have poor ductility and low energy dissipation capacity, and they are often the first to fail under the action of a large earthquake, which in turn leads to the collapse of the structure. These disadvantages limit the use and development of precast concrete structures in earthquake zones. [0003] ...
