The Dinamic Response Analysis of the Viaduct Supported on Anti Seismic Systems with Selective Links as Viscoelastic and Dry Friction Type
MetadataShow full item record
This paper analyzes, on the theoretical level, the dynamic response of a viaduct section, dynamically isolated by systems with a selective type of links with viscoelastic and with dry friction. Evaluation of kinematic parameters of the dynamic response was performed in theory, in hypothesis of loaded system by impulsive actions coming from a truck passing over an obstacle placed across the road surface. There have been emphasized quantitative differences which in the cinematic parameters of the deck vibration for two considered cases: the case of using only the viscoelastic insulation type systems and the case of using viscoelastic insulation type systems with dry friction.
