A structural spanning system that may be embodied by a cable array bridge system, which typically includes a pair of inclined towers separated by a horizontal distance spanned by a bridge deck and oriented at an outward angle. On opposing ends of the central bridge deck, the towers, and/or columns are secured at a common fulcrum. The columns are similarly oriented at an angle relative to a horizontal plane between fulcrums. Upper cables between towers extend to the deck and create a perpendicular force vector where they connect and are tensioned across the shallow arch bridge deck. Lower cables extend between opposing inclined columns, with one or more stringer cables extending between the lower cables and the bridge deck. Securing the lower cables to the deck via the stringer cables stabilizes the deck in tension by a counterforce to the upper cables. As a result, the bridge deck experiences a balanced pre-stress of upper cable forces in tension through the network of cables.

The present application relates to a wind-resistant suspension bridge, including a bridge tower, a bridge body, a main rope, a suspension rope and a guardrail. The suspension bridge further includes a wind-resistant rope, one end of which is connected to the bridge tower and the other end of which is connected to the main rope. The wind-resistant rope, the main rope and the bridge tower form a substantially triangle. The contact point between the bridge tower and the main rope, the connection point between the wind-resistant rope and the main rope, and the connection point between the wind-resistant rope and the bridge tower form the three vertices of the substantially triangle.

The invention relates to the technological field of bridge structures, in particular to a long-service-life PWS cable with replaceable sleeve and shielding gas. It consists of wire strands, wrapping tape covering the wire strands, and a sheath arranged outside the wire strands, and is characterized in that the sheath is covered with an outer protective sleeve and shielding gas is filled between the wires in the wire strands. The wire strands of the present invention is completely under protection in a shielding gas environment which effectively avoids the corrosion of the wire strands; the protective sleeve outside the sheath of the PWS cable is a replaceable segmented and fragmented sleeve structure, which is convenient to be replaced and installed, substantially prolonging the service life of the PWS cable system with great promotional value achieved.

The structural cable of a construction work comprises a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, and at least one vibration module received within the sheath and configured to generate vibrations to break superficial ice or frost deposits on the cable.

An aircraft boarding apparatus has a passenger bridge that has a confinement structure coupled to the second passenger bridge. The confinement structure exerts a ground-anchoring effect on the second passenger bridge to offset the ultralight configuration of the passenger bridge.
