PRESTRESSED STAY CABLE FOR CABLE-STAYED BRIDGES

摘要

it uses at least one tower bridge (14) vertically supported by a battery (15) together with a deck (11) carrying the traffic, the bridge girder is supported by cables (16). several struts (12) are anchored to the upper end of the tower and extends at an angle to the deck, and through it, and cables are anchored to the beam.each strut is prestressed cable and includes a group of inner strands (25) contained in a lubricated tube (26) and a rigid structural unit, external cable strands (27) in a rigid structural pipe (37). the tube surrounds the outer rigid structural panel of external cables and is separated from it by a grout cement (28).each group of wires includes anchors (41, 42) on its upper and lower ends. the prestress is between the ends, and a desired voltage.
