The Lohr Structures Laboratory is located in Crothers Engineering Hall, room 141, on the Campus of South Dakota State University (SDSU). Covering an area of 4000 ft², the Lohr Structures Laboratory is a high-bay/strong-floor structural testing facility that is configured to accommodate large-and full-scale test specimens. Engineering faculty members at SDSU utilize the laboratory for research, teaching, and outreach activities in the field of Structural Engineering, Mechanical Engineering, and Materials.
