RENO, NEVADA - Dynamic Isolation Systems has developed technology RENO, NEVADA - Dynamic Isolation Systems has developed technology which provides protection against vertical accelerations in low mass applications during a seismic event.
Seismic isolation is generally engineered to protect against horizontal accelerations in an earthquake, however in certain applications, significant vertical accelerations are present as well and, until now, there has been no effective solution to minimize the resulting forces and motions.
Recently, DIS was approached by the engineers of a major hydro-electric dam project seeking protection for the dams' operational equipment, which is located atop the structure. The equipment was designed to meet IEEE 693 high performance spectra.
Engineers at DIS developed a system which provides X, Y, and Z isolation far in excess of the anticipated needs of the project. The spectral accelerations were reduced by a factor of 18, protecting the equipment against the most extreme conditions.
Dynamic Isolation Systems President, Konrad Eriksen, predicts that this technology will be very useful in protecting critical equipment. "This is exactly the solution that has been needed.' he said.
"Every project is different." Eriksen said, "We are confident that an engineering solution can be found to protect any equipment against earthquakes".
