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. The foundation for the testing area is Testing Floor and L-Shaped Reaction Wall.
