Surface Force

These structures composed of Flexible steel cables are frequently employed to support bridges and long-span roofs. Because of the flexibility of this structure, cables have negligible bending stiffness, thus, under external loads, a cable adopts a shape that enables it to support the load by tensile forces alone. In other words, the shape of the cable changes as the loads acting on it change.
