Coronavirus information

In response to the COVID-19 global pandemic, the University of Alaska Anchorage has taken steps to protect the health and safety of our campus community. Visit the University of Alaska Coronavirus Information website to learn how UAA and the university system are responding to this situation. Find links to communications, policy guidance, resources and information about the university's community restrictions, which apply to all faculty, staff and students. The UAA Student Health and Counseling Center remains open at this time to serve UAA students.

Structures Testing Lab

Overview

The STL was designed to test large specimens and components of structures. This facility includes a 3-foot-thick concrete strong floor and a structural steel load frame. We can accommodate test specimens:

  • up to 15' tall
  • up to 20' long

Current Load Capacity

  • ±500 kN (±110 kips)
  • 20" piston stroke
  • 30 gpm hydraulic power unit
  • Quasi-static and pseudo-dynamic load environments
  • MTS Flex-test Controller® - custom load functions

Planned Load Capacity (grant proposals pending)

  • One 1 MN actuator* - 10" stroke
    • Quasi-static environment
    • 215 kips (965 kN) tension; 330 kips (1460 kN) compression
    • Possible 2 MN configuration for Tension and Compression
      • 660 kips tension; 430 kips compression
  • One ±100 kN actuator - 10" stroke
    • Dynamic environment
    • Piston head velocity ~15 in/s

* funding for the 1MN  actuator has been awarded and expected to be installed in January 2018

Specimen Fixtures

  • Tension/Compression: 1 MN capacity
  • Flexure: 1 MN capacity
  • Lateral Load: 500kN capacity

Models for Providing Services to Industry

Research Grant

  • Long-term study
    • Fundamental research
    • Applied research

Short-form Contract

  • Standard UAA contract
  • Contract generally accepted by all parties as-is
  • Best for projects that are time-critical

Master Services Agreement (MSA)

  • Provide testing services as needed
  • Each negotiated scope of work performed under MSA
  • Saves time (once MSA is in place)
  • Best when multiple services may be needed over an extended period

Cost Center (Anticipated 4th Quarter 2017)

  • Set time-and-materials rate
  • No contract
  • Deliverables upon receipt of payment
  • Smaller projects with short timeframe
