A self-resetting steel tube concrete column-steel beam node connection device, comprising a steel tube concrete column and steel beams symmetrically connected on both sides of the steel tube concrete column through connecting steel plates, and connected between the upper and lower flanges of the steel beam and the sides of the steel tube concrete column Two sets of anchor plates at a certain distance are arranged symmetrically on both sides of the web of the steel beam, and the upper and lower prestressed steel bars and Lower prestressed reinforcement. The beam-column joints are connected by steel plate bolts, and the local prestressed steel bars pass through the column body and are anchored at the beam end to realize self-resetting. The three relative friction slide to consume energy. The invention has convenient connection and simple structure, and most of them are connected by bolts, which can realize assembly. After an earthquake, it can absorb and dissipate shock and automatically reset, and can be widely used in the technical field of shock and energy dissipation of building structures.
Description
technical field [0001] The invention relates to the field of anti-seismic technology of building structures, in particular to a self-resetting steel pipe concrete column-steel beam node connection device. Background technique [0002] Earthquake is a sudden natural disaster, which often brings huge disasters to human beings, resulting in property losses, casualties, and house collapses. With the continuous development of anti-seismic technology, the traditional building has achieved the anti-seismic fortification goal of "not falling down in a big earthquake", but the traditional building consumes the energy input by the earthquake through the plastic deformation of the main anti-lateral force components. After the earthquake, the building experienced excessive plastic deformation, and the repair of the building after the earthquake was very difficult, and the maintenance cost was high, and the normal use of the building would be interrupted at the same time. Therefore, it ...
