摘要

Passive seismic control strategies are based on the reduction of energy, which may affect a structure in case of earthquake events. Some well known approaches make use of frictional, plastic, or other energy dissipating behaviour of special devices. The following presentation reflects some basic ideas for the increase of elasticity and viscous damping for different types of structures. Spring elements may provide local elasticity and attract a great extent 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. Viscodampers, installed beside the spring elements, have the task to absorb the kinetic energy. They serve as a displacement limitation of the structure and the devices. The safety against collapse and defined states of serviceability of the structures can be assured. Induced accelerations and internal stresses of important members are reduced significantly when compared to the behaviour of the unprotected system.
