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 کاملNew Seismic Isolation System for Irregular Structure with the Largest Isolation Building Area in the World
A very large platform (2 stories RC frame) with plane size 1500m wide and 2000m long was built to cover the city railway communication hub area. About 50 isolation house buildings (9 stories RC frame) with 480,000 M were built on the top floor of platform. A new advanced isolation system named Storied-Isolation was used to ensure the seismic safety for this irregular structure with the largest ...
متن کاملStudy on corollary of seismic base isolation system on buildings with soft storey
Soft storey buildings are characterized by having a storey which has a lot of open spaces. This soft storey creates a major weak point in an earthquake. Since soft stories are classically associated with retail spaces and parking garages, they are often on the lower stories of a building, which means that when they collapse, they can take the whole building down with them, causing serious struc...
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...
