The use of driving down
Schmidt (France) in his report announced the plate of the carriageway common in France, formed from a combination of curved steel sheet and concrete layer, the joint work of which is ensured by the use of inclined steel flexible stops and upper rods. Currently, the passing part used is also used more broadly as an element of the main supporting structure, which leads to the spatial work of the structure.

Therefore, the development and implementation of methods of such a spatial calculation acquires the most important practical significance. On the issue of aerodynamic stability of the hanging bridges of large spans, the Leonardt (Germany) report presented to Congress, in which he previously analyzed the transverse sections of some hanging bridges in terms of their aerodynamic stability. He quite rightly described the cross section of the famous such as a span of 855 m, which in 1940., Due to the sharp development of fluctuations that arose under the influence of the wind of significant intensity, a span, suspended to supporting cables. The use of driving down, continuous stiffeners with a distance between their axes equal to everything – to a large extent contributed to a decrease in the aerodynamic stability of the bridge. The aerodynamic characteristics of the other American hanging bridge Mokinak with an average span of 1140 m, which have two through beams of stiffness 12 m high with a distance between their axes of 20.4 and with longitudinal ties in the plane of the lower belts of the beams, are more favorable.
