METHOD OF SUSPENDING BRIDGE GIRDER SUSPENSION BRIDGE |
摘要 |
<p>A method of suspending a bridge-girder of a suspension bridge is provided. The method is characterized in that where the bridge-girder is suspended by main cables supported by main towers through hanger ropes, the central portion of each of a plurality of horizontal beams mounted on each of the main towers in spaced part relationships with one another vertically are connected to the lateral sides of the bridge-girder by means of obliquely extending auxiliary cables 7. According to this suspension method, the torsional natural frequency of the bridge-girder increases so that the flutters and vortex induced oscillation harmful to the bridge-girder are controlled. <IMAGE></p> |
