Technical Field

The invention relates to the technical field of civil engineering earthquake resistance, in particular to an energy dissipation and shock absorption component applied to the field of structure and bridge engineering.

Background

Earthquake is a serious natural disaster, which can cause the damage and even collapse of the building structure, and brings serious threat to people. Building earthquake resistance is an important subject all the time, and in 2011, Chinese scholars define a new concept of structural earthquake resistance design, namely a recoverable functional structure. The recoverable functional structure is a structure which can recover the use function of the structure without repairing the structure or slightly repairing the structure in a partial use state after a defense setting or rare earthquake, and the structure is easy to build and maintain, and has long service life and high cost benefit. The earthquake can generate huge damage to the structure, on one hand, the structure collapses or generates larger lateral deformation during earthquake because the existing structure does not have the capacity of resisting complex earthquake, on the other hand, the structure generates larger residual displacement after the earthquake action, the existence of the residual displacement can seriously damage the capacity of resisting aftershock of the structure, and particularly when the residual deformation angle is more than 0.5%, the structure repairing cost is more than the reconstruction cost. And the problem of permanent displacement can be effectively solved by dissipating earthquake energy during earthquake and self-resetting of the earthquake-caused structure.

The improvement of the earthquake resistance and the post-earthquake restorability of the structure is the main content of research of a plurality of scholars in recent years. At present, scholars at home and abroad have invented a plurality of supports, including an energy consumption part and a self-resetting part. The energy consumption part mainly consumes energy through viscous liquid, friction energy and metal deformation energy; the self-reset part is mainly realized by shape memory alloy, steel strands and springs. The invention adopts the deformation of the disc spring and the metal to respectively realize the self-reset and the energy consumption of the structure.
