Passive Seismic Control Strategies for Buildings and Equipment

Speaker:

Peter Dr. Nawrotzki, GERB Schwinungsisolierungen GmbH & Co.KG, Germany

Synopsis:

Passive seismic control strategies are based on the reduction of energy which may affect a structure in case of an earthquake event. The presentation reflects some basic ideas for the increase of elasticity and damping for different types of structures. Helical spring elements provide local elasticity and they attract a great extend of the seismic energy. In many cases they represent the most flexible part of the structure. In comparison to common structural members they are designed for high operational and seismic demands. Even when considering severe earthquakes these elements remains in the elastic range when the system is combined with suitable damping mechanisms.

The efficiency of the described strategies is discussed by results of numerical analyses of several executed projects in seismically active regions: turbine foundation / machine buildings / other equipment in nuclear facilities, equipment in substations, buildings.
