Beams, arches, trusses, suspension systems, loads, foundations, and materials.
Structures must safely carry their own weight plus people, vehicles, wind, water, earthquakes, and other forces. Bridges make these engineering ideas especially visible.

Learn MoreLoads shows how engineers turn scientific ideas into practical systems. Engineers begin with a problem, define requirements, compare possible designs, calculate forces or performance, build models or prototypes, and test results. For loads, success is not only about making something work. Safety, reliability, cost, maintenance, energy use, materials, accessibility, and environmental effects are also part of the design. Modern projects usually involve teams with several specialties.
