Large structures, like bridges, buildings, and dams, must endure tremendous forces, starting with their own weight. Of course, added to this are externally applied forces, including vehicular and pedestrian traffic, furniture and equipment, and natural elements like wind, snow, and rain. This interactive activity from the Building Big Web site describes some of the forces, or loads, that structures endure and illustrates the damaging effects these forces sometimes have.
