The Newmark Structural Engineering Laboratory (NSEL) of the Department of Civil and Environmental Engineering has a long history of excellence in large-scale, experimental structural research and over the years has contributed greatly to the state-of-the-art in civil engineering. The structural testing section of the laboratory is a versatile area with a three-story clear height that can be used to carry out a wide range of tests of building materials, components, structural assembles, and models. Included in the testing area is a twenty-eight foot tall, L-shaped reaction wall and multi-axial loading units for seismic related experimental research.
