摘要： Ice mitigation for bridge cables is provided by a system having a plurality of heaters on one or more bridge cables, extending parallel to a longitudinal axis thereof, arranged in a plurality of heater sections, and configured to heat an outer surface of the bridge cables, and a control system including one or more controllers configured to individually activate and regulate heating output of the heater sections to prevent snow or ice from falling from the bridge cables. The heater sections can be arranged radially, about a circumference of the bridge cables, and/or axially, end to end along a length of the bridge cables, so that power can be individually directed to the heater sections to account for differing heating requirements at different radial and/or axial aspects of the bridge cables.

摘要： A fire protection device for a structural cable is proposed including taught metal reinforcements (32) and having a first stretch (41), a second stretch (42) and a connection zone (40) of a collar (30) located between the first and second stretches. The fire protection device comprises a protective mat (34) surrounding the structural cable (16) in the first and second stretches (41, 42) and interrupted in the connection zone (40), and a thermally insulating ring (36) more rigid than the protective mat (34), arranged between the reinforcements (32) and the collar (30) in the connection zone (40) and cooperating with the protective mat in order to provide the reinforcements with a continuous thermal protection along the first stretch (41), of the connection zone (40) and of the second stretch (42).

摘要： A bridge deck suspended from a support beam where the deck describes a laterally curved shape, for example an arch having an apex between two deck ends. The support beam describes a laterally curved shape similar to that of the deck, for example an arch having an apex and two ends opposite to the apex that are secured in a base (foundation) in the ground. The support beam is generally inclined from the support's base foundations to the apex at an angle sufficient to position the support above the deck. The support's relative position, dimensions and shape are such that the majority of the supporting beam is above and approximately horizontally aligned with corresponding points of the deck, thereby allowing suspension cables to extend near vertically between attachment points on the support beam and corresponding attachment points on the aligned portions of the deck.

摘要： A cable-stay cradle system (“cradle system”) for cable stayed bridges is mounted onto a cable stay, the opposite ends of which are attached to anchors on a bridge deck. The cradle system is disposed along the length of the cable stay and located in a pre-formed opening in a pylon. The cradle system includes axially spaced sleeve centering plates that have radially spaced holes through which the cable strands of the cable stay are threaded. The cradle system ensures that a distance from center-points of adjacent cable strands remains essentially constant along the entire length of the cradle system. The invention also provides a method of installing a cable stay including a cradle system, which includes the steps of threading the cable stay through the opening in the pylon so as to locate the cradle system in the opening, and attaching the cable stay to anchors on the bridge deck.

摘要： An encapsulated cable for a suspension bridge or a cable-stayed bridge, the cable (10) being encapsulated by a wrap (16) which is formed by spirally winding a flexible strand (S) of a synthetic rubber tightly therearound. The strand is wound with each wind thereof overlapping one-half the width of the preceding wind, thereby forming a uniform thickness, double layer wrap. After the spiral winding step the wrap is heated to heat seal the superimposed layers to one another to thereby seal the seam formed therebetween and shrink the wrap into tight engagement with the cable. The strand, specifically the outermost layer of a laminated multiple layer strand, is precolored with a suitable colorant to eliminate the need for after painting the wrap to obtain a suitable color match between it and adjacent portions of the bridge structure. A joint between the cable and an annular opening in a support member (14) through which it passes is sealed before the spiral wrapping step by positioning an elastomeric annular member (20) around the cable in engagement with the cable and the support member, tightly circumscribing the annular member with a synthetic rubber sleeve (26) to ensure that its engagement with the support member and the cable is sealing engagement, and then by performing the cable spiral wrapping step beginning at the support member to cover the synthetic rubber sleeve as well as the portion of the cable extending therebeyond.
