Product Description

Overview

Principles of Construction

Viscous damping wall is a new type of velocity dependent damping device composed of steel plates and high viscosity materials. It utilizes the relative motion between structural layers to make the steel plates fixed between the upper and lower floors repeatedly move in a closed high viscosity damping fluid. As a result, the damping fluid undergoes shear deformation, and energy is consumed through the internal frictional force generated by material flow, thereby reducing the seismic or wind-induced response of the structure and playing a good role in earthquake resistance and wind resistance
 

 

Product advantages
1. Provide high resistance force:
Viscous damping walls can significantly provide structural damping, effectively reducing the seismic response of the structure. Experiments have shown that structures with viscous damping walls can reduce the peak acceleration by 25% -70% in earthquake simulations, and the damping ratio of the model can also be significantly improved.
2. Strong applicability:
Viscous damping walls are suitable for both seismic design of new buildings and seismic reinforcement of existing buildings. Its shape is similar to a reinforced concrete shear wall, which is easy to set up and does not hinder the building's function. Moreover, the wall thickness is relatively small, which helps with the overall functional design of the building.
3. Good cycling performance:
Viscous damping walls have excellent cyclic performance, which is very effective for earthquakes with long duration and multiple cycles, and can also meet the requirements of wind vibration comfort for high-rise buildings.
4. Economically efficient:
The use of viscous damping walls can reduce the number of shear walls, beam column reinforcement, and the cross-sectional size of components, thereby saving costs. In addition, its maintenance costs are relatively low, reducing the cost of long-term use
 

Specification

Product Name	Viscous Damping Wall(VDW)
Working Principle	The working principle of a viscous damping wall is to move a steel plate in a closed high viscosity damping fluid, causing the damping fluid to undergo shear deformation, thereby consuming vibration energy. Specifically: 1. When an earthquake or other external vibration force acts on a building, the building structure will vibrate, causing relative velocity between the inner and outer steel plates of the viscous damping wall. 2. The steel plate moves in a closed high viscosity damping fluid, causing the damping fluid to experience shear deformation. This shear deformation leads to internal friction within the damping fluid, which converts vibration energy into thermal energy and consumes it. 3. The viscous properties of viscous damping materials can effectively dissipate vibration energy, preventing it from transmitting to the surrounding environment, thereby reducing the impact of noise and vibration on the surrounding environment of buildings. 4. When the vibration stops, the viscous damping material will quickly return to its original state to cope with the next vibration. The whole process is a cycle, making the building more stable and safe under seismic and other vibration forces. In addition, the filling material used in the viscous damping wall is not prone to aging and is basically not in contact with air, with almost no change in performance during normal use
Product Structure	Viscous damping walls are mainly composed of dampers, supporting structures, and other components. Damper: It is the core component of a viscous damping wall, composed of viscous materials and metal components. Viscous materials are usually high molecular weight polymers with strong viscosity and energy dissipation capabilities. During earthquakes or wind-induced vibrations, dampers absorb and dissipate energy through the shear deformation of viscous materials, thereby reducing the vibration amplitude of building structures. Supporting structure: mainly used to fix dampers and connect them to building structures. Supporting structures are usually made of materials such as steel or concrete, with sufficient strength and stability to ensure effective transmission of the resistance generated by dampers during earthquakes or wind-induced vibrations.
Applications	Viscous damping walls are mainly used in seismic reinforcement and renovation of new construction projects and existing buildings. In new construction projects, viscous damping walls can reduce the seismic force acting on the structure, decrease the displacement control index of the structure, and improve the safety of the building. At the same time, it can also reduce the reinforcement amount of the main structural components, optimize the cross-sectional dimensions of the structural components, and thus increase the practical area of the building. In addition, in large public buildings such as schools, hospitals, office buildings, hotels, and shopping malls, as well as between the outer frame and inner tube of high-rise or super high-rise buildings, viscous damping walls can play an important role in improving the overall stability and seismic safety of the building. For existing buildings, viscous damping walls also have important application value. By using viscous damping wall technology, the reinforcement and strengthening amount of main structural components such as beams and columns can be reduced, thereby reducing the seismic response of buildings. At the same time, it can also improve the energy dissipation capacity of the structure and enhance the seismic performance of the building.
