Previous laboratory testing of T-shaped walls loaded uniaxially along the direction of the stem of the T has indicated that these walls can be detailed using methods similar to those used for rectangular walls. However, multidirectional loading of these walls has not been carried out at large scales. This more complicated but more realistic loading scheme will provide additional understanding of the behavior of these members under real-world loading histories. The Multi-Axial Subassemblage Testing (MAST) System at the University of Minnesota, part of the National Science Foundation (NSF) George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES), is the first facility of its kind capable of applying full 6-DOF mixed-mode loading to large-scale specimens. In this project 1 half-scale T-shaped wall, 1 three-quarter-scale T-shaped wall, and 3 half-scale rectangular walls were tested.
