Defining effective locations for sensitive equipment in multistory facilities is always a challenge

The goal of this project is to validate seismic protection options for sets and pieces of equipment and components in essential multistory facilities. The research aims at evaluating and validating the efficacy of strategic settings containing isolation devices and energy dissipation mechanisms. The project involves theoretical analysis and real-environment, full-scale laboratory tests.

The envisioned seismic protective options are flexible mechanisms tailored to control or avoid earthquake damage or malfunctioning of equipment and components by reducing accelerations and by controlling deformations and displacements.

New construction and retrofit of essential facilities should meet or exceed the highest level of seismic performance. Meeting this target can represent significant challenges to structural engineers when relaying only on conventional seismic strategies.

Some challenges implementing conventional seismic strategies: *Ground motion amplified by the structure *Interstory drift *Floor accelerations

Seismic isolation devices and energy dissipation mechanisms have emerged to provide overall structural and nonstructural protection against the damaging effects of earthquakes-an effectiveness that has been settled.

This project addresses critical needs of the earthquake engineering community. It validates high-performance and cost-effective options to protect equipment and components of essential facilities.

The research and education program includes both industry cooperation for systems implementation and a comprehensive educational program.
