    摘要: Disclosed is a composite capping beam with a steel beam and an ultra-high-performance concrete plate. The composite capping beam includes a steel beam and an ultra-high-performance concrete (UHPC) plate, where the steel beam includes a bottom plate and web plates, the web plates are arranged at two sides of the bottom plate in a longitudinal bridge direction, bottoms of the web plates extend downwards to be provided with lower extension sections, and the UHPC plate is clamped in a cavity defined by the lower extension sections and the bottom plate. The present disclosure further provides a construction method for the composite capping beam with a steel beam and an ultra-high-performance concrete plate. The composite capping beam with a steel beam and an ultra-high-performance concrete plate according to the present disclosure is small in hoisting weight and economical.

    摘要: The present invention belongs to the technical field of wind-induced vibration control study of bridges, and provides a dangling net cloth device for suppressing flutter of a sea-crossing bridge, i.e., a large-area dangling net cloth equipped with multiple balance weights, which is suspended below a girder by ropes and is immersed in water . When wind-induced vibration occurs on a bridge, the device is driven to move in the water, and gravity of the device as well as a huge additional mass force and an additional damping force produced by the water on the net cloth will do negative work on the girder to consume vibration energy of the bridge and effectively suppress large vibration of the bridge. The device adopts lightweight standardized components which are convenient to install, detach, transport, and store, and has the advantages of safety, reliability, economy, and practicality.

    摘要: A deck system is disclosed having a mounting plate with a planar support surface and at least one locating rod extending from the support surface. The locating rod extends in a direction that is substantially perpendicular to the support surface. A beam having a first end and a second end is positioned on the support surface of the mounting plate. The first and second ends of the beam have a slot and the slot is disposed for receiving the locating rod. At least one tread is disposed to extend between the two spaced apart parallel oriented beams. The tread has opposed shoulders on the side of the tread that engages the spaced apart beams. The opposed shoulders are disposed for engaging a side of the spaced apart beams that are in adjacent relationship.

    摘要: A first arch and second arch are produced in respective first and second structural portions. Each arch has a tie rod interconnecting the foot points of the arch, where a foot point of the arch is displaceably mounted. Each tie rod is tensioned so that horizontal forces caused by the weight of the arches at the foot points of the corresponding arch, are taken up by the tie rods. A first end point of the tie rod of the first arch is connected in a force-fitting manner to the first abutment, and a second end point of the tie rod of a last arch is connected in a force-fitting manner to the second abutment. The remaining adjoining end points of the tie rods are connected to one another in a force-fitting manner, and corresponding foot points of the arches are connected in a force-fitting manner to the abutments and pillar.

    摘要: A damping device for damping vibrations of a bridge with a bridge deck comprises at least one damping wing comprising a center and configured to dampen vibrations of the bridge. A longitudinal direction of the at least one damping wing is disposed parallel to a longitudinal direction of the bridge deck and the at least one damping wing is stationary upon wind acting on the bridge in a given direction. At least one support structure is laterally attached to at least one side of the bridge deck and configured to attach the at least one damping wing to the bridge deck such that the at least one damping wing is disposed with a lateral offset from an outer edge of the bridge deck facing the at least one damping wing.
