BRIDGE SUPPORT Russian patent published in 2001 - IPC

FIELD: bridge engineering. SUBSTANCE: bridge support has head and round-section reinforced concrete posts placed together with longitudinal and transversal reinforcement in pre-drilled bores in ground. Novelty is that sectors of circle forming cross-sectional areas of post, where sector chords A₁ are arranged in parallel with longitudinal axis of bridge, are reinforced by longitudinal members of total area F₁; circle sectors forming cross-sectional area of post, where sector chords A₂ are arranged perpendicular to longitudinal axis of bridge, are reinforced by longitudinal members of total area F_2,; their equation are given in description of invention. Sector chords A₁ and A₂ are equal in length. EFFECT: reduced metal input of posts due to optimal arrangement of reinforcing bars in post sections. 7 cl, 4 dwg
