Description
Technical Field
The invention belongs to the field of energy dissipation and shock absorption of structural engineering, and particularly relates to a high-performance ring spring self-resetting composite energy-consuming wall damper and an assembly method thereof.
Background
Earthquakes are sudden and unpredictable, are highly destructive and difficult to defend, and have great influence on society. Compared with the traditional anti-seismic measures, the more reasonable shock absorption and energy dissipation technology combines the additional shock absorption device with the original structure for use, achieves the shock absorption effect, and opens up a new road for the anti-seismic technology. Common devices include energy consuming supports, dampers, and the like. The traditional energy dissipation and shock absorption device can cause the structure to generate larger residual deformation after strong shock, and has serious influence on the damage or collapse of the structure. With the design idea of recoverable functional structure and the continuous progress and development of the shock-absorbing device, the research of the self-resetting damper gradually becomes an engineering hotspot.
Self-resetting systems are of a wide variety of classes, and can generally be divided into two general classes: (1) the traditional energy dissipation and shock absorption device is combined with a self-resetting component (SMA wire, SMA rod and the like), so that the traditional energy dissipation and shock absorption device has an energy dissipation function and a self-resetting function. (2) The non-traditional damper or the energy consumption supporting device is combined with the prestressed tendon to form a device with energy consumption and support. However, due to the limitation of the elastic deformation capability of the prestressed tendon, the self-resetting capability of the damper is yet to be improved, and the application and maintenance of the prestress are greatly influenced by external conditions, which may cause a large deviation between the long-term performance and the original design performance of the damper; SMA wires are expensive to manufacture, are greatly affected by temperature, and are not suitable for large-scale application in building structures. Therefore, the self-resetting capability of the current self-resetting damper is to be improved, and the problems of non-ideal resetting effect or high manufacturing cost exist. In addition, the damper of the traditional single energy consumption mechanism has insufficient energy consumption capability in the face of seismic action with high randomness and strong action.
The existing damper connecting mode is mainly connected in a supporting mode, such as: a gantry type support, a double V-shaped support, a double gantry type support, etc. However, the support connection form not only affects the building beauty, but also is inconvenient for opening doors and windows, and has great influence on the building layout. In recent years, wall type connection (also called middle column type connection or buttress type connection) is mostly adopted in engineering, and the form has flexible layout, simple and convenient installation and maintenance and wide application prospect. Therefore, a novel wall type damper with good, stable and self-resetting capability and multiple composite energy consumptions is developed, and a novel way for applying an energy consumption and shock absorption technology in practical engineering is provided.
