Dynamic Hydraulic Dampers for Earthquake Isolated Structural Systems

This paper presents some solutions on hydraulic devices such as linear motors with direct and reverse reaction with the stabilizing role of building movement under the earthquake action. It emphasizes the possibilities of modelling, analysis and serviceable realization of hydraulic dampers with two main functions: dissipation of the transmitted energy to a building, on the one hand, and providing a relatively constant speed with sufficiently low values, on the other hand.
