Suspension Bridge: A bridge characterized by large cables strung between towers, from which the deck is suspended, enabling long spans.
Aerodynamic Forces: The forces exerted by moving air on structures, which can impact the stability of bridges.
Stiffening Trusses: Structural elements added to the sides of a bridge deck to enhance rigidity and resist torsional forces, particularly from wind.
Anchorages: Massive, heavy structures at the ends of suspension bridge cables designed to resist the immense pull of the cables.
