The University of Minnesota's Multi-Axial Subassemblage Testing (MAST) Laboratory, the largest test system of its kind in the world, provides a powerful tool for investigating the effects of earthquakes, hurricanes, and other extreme events on large structural components up to several stories tall.

Key features of the MAST Laboratory include:

  • Sophisticated six-degrees-of-freedom (DOF) control system that enables the application of complex multi-directional deformation or loading schemes to structural subassemblages
  • Ability to apply large loads and deformations to test large-scale structural subassemblages including portions of beam-column frame systems, walls, tanks, and bridge piers
  • Integrated Quasi-Static Hybrid Simulation using the OpenFresco open-source framework
  • High capacity data acquisition system for collecting sensor information and three-dimensional positional information via optical measuring system
  • Remotely-controllable telepresence capabilities including capturing of high-resolution images
