Structural LAB (SLAB)

This is a brand new lab for large-scale testing and is a unique facility in Idaho.

  • Capable of testing specimens up to 38 ft. in length and 14 ft. height
  • Total Lab Area = 1520 sq. ft
  • Strong floor is 2 ft. deep and 875 sq. ft of structural floor
  • 374 anchor sleeves (each rated 100 kips) in grids of 18in
  • The hydraulic actuators can collectively produce force of 1.3 million lbs.
  • Heavy duty steel reaction frames designed for 400 kips loading
  • Dual servo-valve hydraulic actuators (static and dynamic), each with 160 kips capacity and ±12”stroke
  • Fatigue testing machine and frame with servo-valve MTS hydraulic actuator (22 kips capacity, ±3” stroke, 31 in/sec velocity, up to 50 Hz frequency)
  • Tinius Olsen Universal Testing Machine, 120 kips capacity and ±12” stroke
  • Enerpac ram, 440 kips capacity, and 6” stroke
  • Hydraforce hollow ram, 220 kips capacity, and 3” stroke
  • Six servo-valve hydraulic actuators (static) with 10 kips capacity and ±4” stroke
  • Several hydraulic pumps, jacks, and accessories
  • Controller system for hydraulic actuators with data acquisition for 20 channels
  • Brand new Campbell Scientific data acquisition system with 96 channels, and up to 800 Hz sampling rate
