The structural engineer is responsible for the analysis, design, and construction of traditional civil engineering structures including buildings, bridges, concrete dams, tanks and towers, as well as a great diversity of other structures, such as radio telescopes, reactor containment vessels, cooling towers, railway, automotive, and aerospace vehicles, ships, space stations, and roller coasters. Specific topics include the study of loads and load combinations, calculation of internal forces and stresses, determination of material, member, and structural behavior, and technical and economic comparison of alternatives. The foundations for structural engineering are in the basic sciences of mathematics, physics, and chemistry, and in the engineering sciences of mechanics, dynamics, materials, and probability. The distinguishing and essential feature of structural engineering work is the application to real-world problems and needs in support of the broadest range of human activity. Strong attention is given to the properties of different engineering materials. Faculty in the Structural Engineering area include:
