FIELD: bridge building. SUBSTANCE: suspension bridge includes anchors 1 pylons 2, load bearing cables 3 fastened to the pylons and placed on opposite sides about lengthwise bridge axis 0-0. The cables are secured through cable suspensions 4 to stiffness beam 5. Load bearing cables 3 together with suspensions 4 form cable frames being connected to external faces of stiffness beam 5 in nodal points 6. Nodes 6 are numerated from pylons 2 towards bridge span middle. Even and odd nodes of attaching cable suspensions to the stiffness beam are placed on individual straight beams, parallel to bridge lengthwise axis. In so doing straight beams are spaced for a distance equal to stiffness beam height, and straight beam with odd nodes is placed close to bridge lengthwise axis. EFFECT: lower material consumption. 3 dwg |
