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.

A double-ring shaped strong magnet array nonlinear dynamic vibration absorber for vibration mitigation of suspender cables and design method thereof, which belongs to the field of structural vibration control. The installation positions and number are designed according to the demand of vibration mitigation, and usually one is installed at the midpoint of the suspender cable. The vibration absorber consists of the inner and outer magnet ring arrays, the additional weights, the universal wheels and a base. It feeds back the control force in the opposite direction of the motion of the suspender cable during the movement, so that the vibration energy of the suspender cable is transferred to the vibration absorber and thus less is returned to the suspender cable, and the energy dissipated through the friction between the universal wheels and the base, adding air dampers and other measures, etc.

A method and an apparatus monitor the integrity of a wire rope in a wire rope assembly, as well as a wire rope assembly containing such an apparatus. In this case, the wire rope is moved past a sensor device, and a sensor signal is generated with the aid of the sensor device. The sensor signal characterizes a magnetic interaction between the sensor device and the wire rope moving past the sensor device. A measure for the integrity of the wire rope is determined on the basis of the generated sensor signal. Accordingly, the movement of the wire rope is generated here in a normal operation of the wire rope assembly.

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.
