Dynamic Isolation Systems
 
Dynamic Isolation Systems played a key role in the development
of Seismic Isolation Technology including its commercialization
in the 1980's.
 
DIS helped develop codes and provided design and analysis support to engineers and government agencies. Over the past 20 years design earthquakes have increased considerably. DIS has continued to develop its isolators to perform well at large lateral displacements accompanied with high axial loads.

Isolated Projects
Dynamic Isolation Systems has provided over 14,000 isolators for more than 250 bridges and buildings worldwide. Some prominent projects isolated by DIS include the iconic Golden Gate Bridge; San Francisco City Hall that was damaged in the 1989 Loma Prieta Earthquake and Tan Tzu Medical Center in Taiwan. At 1.7 million square feet. it is the largest isolated structure in the world.
 
   
 
Project Support
Dynamic Isolation Systems can assist you with your feasibility study, budget development and value engineering. We have been able to reduce the cost of the isolation system by up to 30% on projects where we can lend our expertise to the isolator layout and product mix. Our Engineers can provide technical support and parameters for structural modeling.
   
 

Manufacturing Capabilities

  • Facility
    Dynamic Isolation Systems’ 60,000 square foot manufacturing facility is located in Sparks, Nevada, USA. It is adjacent to Interstate 80 which allows for ease of freight throughout the United States and worldwide via the Port of Oakland, California.
  • Press Capacities
    Dynamic Isolation Systems molds in custom designed and built presses ranging from 200 to 4400 tons. In response to increased demand for larger sized isolators DIS now has four presses of over 2,000 ton capacity. The largest isolators we have manufactured were 60 inches in diameter and weighed 10 tons each.
  • Machining
    Steel processing is a major part of manufacturing our isolators. Two large computer controlled machining centers process the bulk of our steel plate. They have a capacity to machine up to 80 inch wide plates.
  • Testing
    Our main test rig has a shear displacement of ± 31 inches, a shear force capacity of 700 tons and an axial force capacity of 2,000 tons.

    Testing is also conducted in a smaller machine that has a shear displacement capacity of ± 12 inches, a shear force capacity of 100 tons and an axial force capacity of 600 tons.
