     Welcome to the University of Minnesota's Multi-Axial Subassemblage Testing (MAST) Laboratory, a member of the George E, Brown, Jr. Network for Earthquake Engineering Simulation (NEES). Researchers use the MAST Lab's equipment to twist, compress or stretch components of large structures such as buildings or bridges in order to study what happens to them during earthquakes and other extreme events.
