Seismic 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.
متن کاملDesign Principles of Seismic Isolation
In earthquake resistance design of structures, two general concepts have been used. The first is to increase the capacity of the structures to resist the earthquake load effects (mostly horizontal forces) or to increase the dynamic stiffness such as the seismic energy dissipation ability by adding damping systems (both devices and/or structural fuses). The second concept includes seismic isolat...
متن کاملPillow-Shape Base Isolation System and Its Seismic Behavior
In this paper a new isolating system is introduced for short to mid-rise buildings. In comparison to conventional systems such as LRB and HRB, the proposed system has the advantage of no need to cutting edge technology and has low manufacturing cost. This system is made up of two orthogonal pairs of pillow-shaped rollers that are located between flat bed and plates. By using this system in two ...
متن کاملSeismic Response Control Using Base Isolation Strategy
Earthquakes are one of the natural hazards that occur due to sudden violent movement of earth’s surface which releases energy and has destructive power in many parts of the world. The development of recent technologies for the control of seismic hazards catches the attention of structural engineers to make the structures seismically resistant. The seismic base isolation technique is a passive p...
متن کاملExternal seismic pre-isolation retrofit design
This technical note outlines the design of an external seismic pre-isolation system proposed for use in LIGO Livingston. The goal is to reduce the effects of the site’s excess ground noise in the 1 3 Hz frequency band, allowing detector noise performance equivalent to that of the 4 km LIGO Hanford detector. The center histogram in Figure 8 shows the most troubling aspect of the excess noise qui...
