Building viscous damper is a device used for shock absorption and anti-seismic. Through its special structure and viscous performance, it can effectively reduce the vibration amplitude of buildings under earthquakes or other external impacts and improve the seismic performance of buildings. . Building viscous dampers are mainly composed of viscous shear deformation materials, jacket structures and supports.
Structure: The main structure of the building viscous damper consists of two parts. One part is a viscous shear deformation material, usually a special elastomer material with a complex internal microstructure that can achieve nonlinear deformation under external stress. Thereby absorbing and dissipating the energy caused by earthquakes or other external impacts. The other part is the jacket structure and supports. The jacket structure is generally made of steel or concrete to fix and protect the viscous shear deformation materials. The supports are used to connect the building and the viscous damper.
Production process: The production process of building viscous dampers includes material selection, mold design, molding, assembly and other steps. First, select the appropriate viscous shear deformation material according to the building’s needs and design parameters, and carry out design and calculation. Then the mold is designed to shape the viscous material, and the jacket structure and support are assembled with the viscous material. Finally, the finished product is inspected and debugged to ensure that it meets national standards and design requirements.
Installation method: The installation of building viscous dampers is mainly completed through the connection with the building structure. First determine the installation location and quantity, and then fix the connection between the viscous damper and the building structure to ensure that it can effectively absorb and dissipate the energy caused by earthquakes or other external impacts. During the installation process, attention needs to be paid to the strength and sealing of the connection parts to ensure that they can work properly and do not affect the structural stability of the building.
National standards: The production and installation of building viscous dampers need to comply with relevant national standards and specifications, including building material standards, building structure design specifications, earthquake design specifications, etc. During the selection of materials, design and production processes, it is necessary to operate in accordance with relevant standards and specifications to ensure that the quality and performance of the product meet the requirements. At the same time, it is also necessary to operate in accordance with relevant specifications during the installation process to ensure that the installation position, quantity and connection method of viscous dampers meet the standards, thereby improving the seismic performance of the building.
In summary, building viscous dampers, as an important shock-absorbing device, play an important role in the seismic design and construction of buildings. Through reasonable structural design, strict production technology, correct installation methods and compliance with national standards, building viscous dampers can effectively improve the seismic performance of buildings and ensure the safety of people’s lives and property.
