GERB Viscous Wall Damper (GVWD)

Protection of buildings & structures against earthquakes and wind induced vibrations

GERB Viscous Wall Dampers (GVWD) are a special design of common Viscodampers®. They are installed in buildings and structures connecting different floors. They are reducing inter-storey drift ratios during wind or seismic excitation. GVWD act in one horizontal direction and increase the overall damping of the structure. Reduced inter-storey drifts result in lower internal forces and moments improving comfort, safety and reliability.

GVWDs consist of a steel housing connected to the lower floor/structure, an inner piston connected to the upper floor, and viscous liquid inbetween. During seismic and strong wind excitation, the relative displacement between upper and lower structure causes the piston moving through the viscous liquid. Damping forces are induced and yield kinetic energy dissipation. Depending on the damping required and/or to achieve acceptable relative displacements between the floors, different damper sizes with suitable performance levels can be selected. Several dampers can work in parallel, if required.

GERB Viscous Wall Dampers have been developed and designed to meet the needs of architects and structural engineers. They come in various sizes, can be installed within the regular wall structures, and are suitable for new builds, but also applicable for retrofitting measures.
