TRANSPORT STRUCTURE Russian patent published in 2017 - IPC E01D12/00 

FIELD: construction.

SUBSTANCE: transport structure is made as a single technical solution for the transport construction facility. The transport construction facility contains a span supporting flat or volumetric structural cell that is made of a frame and includes one pair of columns in a flat cell and/or two pairs of columns in a spatial cell of the frame. The span of each pair of columns is overlaid by a beam. The beam has the body comprising the wall, the upper and the lower belts, the supporting sections and the span. The span made with the length L, with a variable cross-sectional configuration along the length and the increasing cross-section height over the major part of the structure length. The lower belt is made convex and curved in the conventional vertical longitudinal plane of the structure symmetry, with the convexity facing down, and having the curvature with the radius R with the centre located above the upper belt at a distance exceeding the span length and satisfying the condition R/L=(5÷15).

EFFECT: increased bearing capacity in terms of perception of different loads and expanding the range of natural oscillations without entering into resonance, while reducing the material consumption and increasing the structure durability.
