Research on Seismic Response and Damping Effect for High-Speed Railway Seismic Isolated Bridge
With the development of high-speed railway in recent years, lots of researchers have been paying more and more attention to the seismic isolation of high-speed railway bridge. The equivalent linear model of hysteretic characteristics of lead rubber bearings (LRB) is presented, the computational method and the varying range of dynamic parameters effecting hysteretic characteristics of LRB are es...
متن کاملAdvances in elastomeric isolators
Seismic hazards remained as a challenge to engineers over ages. In order to reduce loss of life and damage to property due to earthquake, several techniques have been developed among which Seismic Isolation technique using Elastomeric Isolators has gained high acceptance and becoming popular all over the world, due to its simplicity, reliability and overall cost effectiveness. Seismic Isolation...
متن کاملAdaptive fuzzy control for earthquake-excited buildings with lead rubber bearing isolation
This study examines the feasibility of applying adaptive fuzzy sliding mode control (AFSMC) strategies to reduce the dynamic responses of buildings constructed using a lead rubber bearing (LRB) isolation hybrid protective system. Recently developed control devices for civil engineering structures, including hybrid systems and semi-active systems, have been found to have inherent nonlinear prope...

متن کاملSeismic Isolation for Advanced LIGO
The baseline design concept for a seismic isolation component of the proposed “Advanced LIGO” detector upgrade has been developed with proofof-principle experiments and with computer models. It consists of a two-stage in-vacuum active isolation platform that is supported by an external hydraulic actuation stage. Construction is underway for prototype testing of a full-scale preliminary design.
