Abstract

The invention relates to a self-resetting energy-consuming connection device, which belongs to the field of shock absorption and shock isolation. The device is composed of upper wing, lower wing and web to form a fixed structure. The upper wing, lower wing and web are all provided with guide grooves; the beam connecting rod is connected with the arc spring plate, and the end of the arc spring plate There is a friction hinge seat, and the connection mode between the curved elastic plate and the friction hinge seat is hinged, and the friction hinge seat on both sides of the web is connected by the design pretightening force applied by the bolt; There are guide posts. The device is easy to manufacture and easy to install. It is installed between the beam body and the abutment through the beam connecting rod. Under normal circumstances, the relative displacement of the beam body and the abutment is not limited. Under the action of an earthquake, this device can connect the beam body and the abutment. As a whole, the earthquake response is reduced through energy consumption, and it can self-reset after an earthquake.

Description

technical field [0001] The invention relates to a self-resetting energy-consuming connection device, in particular to a self-resetting energy-consuming connection device based on a protection function, which is suitable for shock absorption of beams and columns of bridges and structural buildings, and can make the structure cooperate under the action of a sudden earthquake force and improve the overall seismic performance of the structure. Background technique [0002] my country is an earthquake-prone country, and the previous earthquake damages have promoted the improvement and development of the structural seismic system, but there are still various defects in the seismic performance of existing structures. During the construction of existing continuous girder bridges, although shock-absorbing measures such as shock-absorbing and isolation bearings and viscous dampers have been taken to reduce the seismic response of the bridge and improve the seismic performance of the b...
