Research

Research Uses

The SRL is available to the civil engineering and construction industry in the Pacific Northwest.

With a large-scale testing facility to meet specific project needs, the facility is often used to perform tests for structural engineering design firms, contractors and suppliers. To learn more about utilizing the SRL to support your project needs, please contact the laboratory director.

Examples of Commercial Testing

The SRL provides unique testing capabilities to support the following regional and national engineering and construction needs:

  • Compression testing and/or calibration of hydraulic rams, marine fenders and other equipment and structures using one of three UTMs (110 kip, 300 kip and 2,400 kip)
  • Tension testing of high strength bars, bolts and wire rope using a UTM
  • Flexural and shear testing of beams, piles and other structural systems
  • Fatigue testing of bridge bearings under combined loading
  • Dynamic testing of electrical equipment on a single axis shake table
  • Fatigue testing of connections, welds, epoxy joints, etc.
  • Concrete creep testing
  • Material testing for metals, concrete and composites
  • Custom testing for a range of loading conditions and applications
