Description

A swing damping self-resetting component and its manufacturing method

technical field

The invention relates to the discipline of design civil engineering and the technical field of structural vibration control, in particular to a swing damping self-resetting component and a manufacturing method thereof.

Background technique

The rocking system is a self-resetting passive anti-seismic system that can rotate around its bottom. The rocking structural system does not use the deformation of the structure itself to dissipate the seismic energy, but relaxes the constraints of the structural system to form rocking members. Through the rocking of the structural members, the structure The deformation tends to be consistent, and the deformation is concentrated on the rocking interface, and dampers are set at these parts to dissipate energy. The existing research results show that the rocking wall system can make the deformation of each layer of the structure tend to be uniform, can effectively control the concentration of structural deformation, and can exert the overall seismic and energy dissipation capacity of the structure. The rocking wall system has been practically applied to frame structures, and has shown good anti-seismic effect. This structural form is also applicable to other building structures, and is also applicable to jacket-type offshore platform structures.

At present, the swing system has been applied to practical projects. Although the performance is good, some swing components (such as swing walls) are often large in size, which will limit their planning in terms of construction. In practice, it will also block daylighting, etc. There are many problems, and the layout is not flexible; some swing systems do not have energy dissipation capabilities, and additional dampers are required to dissipate energy. The dampers may not have a good installation position, and even if they are successfully installed, their working efficiency may not be very good. Guarantee; some swing systems have high technical requirements for installation, and the process is cumbersome, which is not conducive to construction, and once damaged, the damaged parts cannot be replaced, and the entire system needs to be replaced; some swing systems cannot be given according to the requirements of the owner The optimized design scheme saves costs to the greatest extent, which is no longer in line with the current mainstream performance-based seismic design concept.

Energy dissipation and shock absorption is one of the main means of building anti-seismic at present. This technology is mature, economical and effective. It has been widely used in new buildings with anti-seismic requirements all over the world. However, most of the existing dampers are linear For the tension-compression damper, in the swing system, the relative linear displacement between the components is small, and it is difficult to achieve the expected energy dissipation effect if the linear tension-compression damper is directly installed. Therefore, there is a need for a damper suitable for the characteristics of the swing system, which can not only ensure the effectiveness of energy consumption, but also has the characteristics of economical and reasonable, easy installation and maintenance.

It can be seen that the current swing system technology is not yet perfect, and the theoretical effect of the swing system is far from being achieved in practical applications, which also limits the large-scale application of the swing system. Therefore, need a kind of scheme that can solve above-mentioned problem to perfect swing system.

Combined with the characteristic that the swing system can rotate around the hinge point, a kind of angular displacement damper is installed at the hinge point of the swing column. When the earthquake comes, the swing column drives the pin shaft to rotate, and the angular displacement damper will rotate the pin shaft. The displacement is converted into linear tension and compression displacement, which drives the viscoelastic damper inside the angular displacement damper to dissipate energy.
