Metal damper

The metal damper uses the mild steel as the shear plate, and takes advantage of its advantages of low yield strength and good ductility. Compared with the main structure, it can enter the yield earlier, so that the cumulative plastic deformation after yielding of the mild steel can be used to achieve the loss. The effect of dispersing seismic energy.

Metal dampers can be widely used in the seismic reinforcement of existing buildings and the reinforcement and repair of earthquake-damaged structures. Compared with traditional reinforcement methods, they can significantly save costs and shorten construction periods. Metal shear dampers are also very suitable for new buildings. According to the performance goals of the structure, they can play the role of energy dissipation and shock absorption under moderate or large earthquakes, which can greatly reduce the seismic response and save the amount of steel used in the structure. The metal shear damper uses the shear deformation of the energy dissipation sheet under the action of earthquake to provide damping to achieve the purpose of dissipating the energy input into the main structure. The installation of the damper is fixed by connecting the connecting plate to the embedded parts in the main components (beams, buttresses, walls). The construction process includes the installation of embedded parts and the connection of dampers. The installation sequence considers that the damper does not bear vertical force and should be installed in the order of lower-up-middle and rear-installed dampers, but it is not easy to construct, and it can also be installed in the order from bottom to top.

Features Large lateral stiffness, high ductility ratio, high material utilization rate and good economy.
