BRIDGE SPANNING STRUCTURE "PROKHOROV TUNNEL - FLEXICON" Russian patent published in 2004 - IPC

Abstract RU 2228990 C1

FIELD: special building structures, particularly for bridge and elevated monorail railway construction. SUBSTANCE: bridge spanning structure or similar is formed of thin resilient sheet, which is integral along the whole length thereof. Sheet is prestressed by creating smooth profile relative vertical plane of symmetry. Sheet edges are superposed for closed structure, namely tunnel, forming. Tunnel has transversal members located into tunnel and spaced at regular intervals. The resultant profile is calculated from mathematical relation. EFFECT: increased rigidity, reduced mass. 3 cl, 4 dwg
