Description
Technical Field
The invention is applied to civil building structures, and particularly relates to a disc spring soft steel energy dissipation and shock absorption device with a self-resetting function.
Background
The traditional structure anti-seismic design is that the earthquake input energy is dissipated by using the self-seismic resistance of the structure, so that the interlayer deformation of the structure under the action of horizontal load is controlled within a specified limit value, the lateral displacement resisting rigidity of the structure is increased by increasing the section size of a beam column to resist the earthquake action, the structure is not economical, the practical application of the frame structure engineering is influenced to a certain extent, and the main body part of the structure can be deformed and damaged greatly under the action of rare earthquakes, so that the structure loses the use function, and cannot be used or recovered after the earthquake, and huge economic property loss is caused.
Recent researches show that the self-resetting energy consumption device serving as a novel bearing energy consumption member can dissipate energy input into a structure in an earthquake process, maintain the integral bearing capacity of the structure and control the residual deformation of the structure after the earthquake, so that the self-resetting energy consumption device not only meets the increasingly developed earthquake-resistant design requirement based on performance, but also has good earthquake-resistant application potential and prospect. Therefore, the shock absorption device with the self-resetting function and the energy consumption capability is developed, the novel shock absorption device integrating the energy consumption capability and the self-resetting capability is formed, the advantages of the supporting structure are fully exerted by applying the shock absorption device in various supporting structures, and the structural system has important significance in rapidly recovering the normal use state after an earthquake.
