Description

Multistage compound viscous fluid damping wall

Technical Field

The utility model relates to the technical field of building damping equipment, in particular to a multistage compound viscous fluid damping wall.

Background

The energy dissipation and shock absorption technology is that energy dissipation components are arranged at certain positions with larger deformation in the structure, or certain components are directly arranged as the energy dissipation components, and under the action of earthquake load and wind load, the energy dissipation components are utilized to quickly enter an energy dissipation state, and part or most of external load is consumed to input energy of the structure, so that the power reaction of the structural main body is reduced, and the possibility of damage to the structural main body is avoided or greatly reduced.

Compared with a viscous fluid damper, the viscous fluid damping wall has the characteristics of simple structure and convenience in installation, and can provide a larger additional damping ratio for the structure. The steel box is just connected to the top of the lower beam through a lower connecting plate, the shear plate is just connected to the bottom of the upper beam through an upper connecting plate, the steel box is filled with high-viscosity viscous damping materials, and the shear plate and the upper connecting plate are welded into a whole. When the floor generates relative displacement or speed, the shearing plate slides in the steel box to shear the high-viscosity viscous damping material to generate damping force, so that the energy of an earthquake or wind load input structure is dissipated, and the dynamic response of the structure is reduced.

The damping force is mainly related to the viscosity of the damping material, the gap between the shearing plate and the box body and the movement speed, and different damping and energy consumption characteristics can be realized by adjusting the parameters.

The traditional shear plate type viscous fluid damping wall approximately accords with the following model: f=cv ^α

Wherein: f represents damping force, C represents damping coefficient, alpha represents damping index, and v represents shear velocity. The hysteresis curve area represents the energy consumption capability.

As can be seen from the above formula, the damping parameters of the viscous fluid damping wall are constant, and the damping parameters are expressed in the seismic calculation: the damping wall has the advantages that larger damping force can be provided for small earthquake, but under the condition of large earthquake, the damping force is relatively increased slightly, the rare earthquake acting force is generally 5-6 times of the rare earthquake acting force, the small increase of the force provided by the damping wall greatly increases the earthquake acting force, and the earthquake resistance of the damping wall energy dissipation and shock absorption structure is poor under the rare earthquake. The damping wall can not adjust the working performance of the damping wall aiming at different working conditions and different structural displacements so as to achieve the purposes of reasonable energy consumption and further structure protection, and limit the wider application of the damping wall in the future higher standard market.

In the face of future higher and higher anti-seismic requirements and more complex application conditions, the limitation of the use performance of the traditional damping wall with basically unchanged damping coefficient determines that the traditional damping wall cannot better meet the subsequent engineering requirements.
