GERB Earthquake Protection Systems
Discussions as well as experience show that damping is a crucial factor to reduce the destructive potential of earthquakes. GERB has been supplying earthquake-proof devices for heavy machinery of various kinds as well as for buildings and other structures since decades. Spring elements and dampers are effective against ground settlements, vibrations and structure borne noise and can successfully be used for earthquake protection purposes. These ideas have constantly been developed and shape earthquake protection measures of today, always tailored to the project specific demands:
- Base Control Systems (BCS) – assembly of the protection elements below the structure
- Tuned Mass Control Systems (TMCS) – special mass damper systems
Systems to increase damping for vulnerable buildings and other structures, such as GERB Viscous Wall Damper (GVWD)
Base Control System
The Base Control System (BCS) consists of helical steel springs and highly efficient Viscodamper®, which are arranged underneath the structure. The system is flexible in horizontal directions, but possesses also a vertical elasticity. Viscodamper® supply absorption forces in horizontal and vertical directions. In particular the resulting demands (e.g. accelerations, base shear etc.) of the structure can be significantly reduced by using the BCS – due to reduction of frequencies and increase of structural damping.
Tuned Mass Control System (TMCS)
Tuned Mass Control Systems (TMCS) are additional mass-spring-damper systems. They provide passively working earthquake protection due to increase of structural damping. The Tuned Mass Control Systems absorb horizontal forces and are practically maintenance-free. Requiring no electrical power supply or any other form of drive or control mechanism they are immediately effective when an earthquake strikes.
GERB Viscous Wall Dampers
GERB Viscous Wall Dampers (GVWD) are a special design of common Viscodampers®. They are installed in buildings and structures connecting different floors adressing shear deformation between them. In this position they are especially reducing interstorey drift ratios during wind or seismic excitation. They act in one horizontal direction and increase the overall damping of the structure. Reduced inter-storey drifts result in lower internal forces and moments in all structural members improving comfort, safety
and reliability.
