A pneumatic support having a body (112) which can be pneumatically pressurised and which, when under operating pressure, operationally holds a compression member (96, 128 to 131′) which extends substantially over the length of the body and a tensile member (98, 138 to 141′) which likewise extends substantially over the length (I) of the body at a distance from each other, wherein the compression member (96, 128 to 131′) and the tensile member (98, 138 to 141′) are connected to each other at the end in connection nodes (91), and wherein the body which can be pneumatically pressurised has pneumatic drop-stitch transverse fibre pressure panels (100, 165, 113 to 116).

The present application belongs to the technical field of bridge engineering, and particularly relates to a structure for relieving cracking of a steel bridge deck. The structure for relieving cracking of a steel bridge deck comprises a steel bridge deck and a plurality of U-ribs welded and fixed to a bottom of the steel bridge deck, and further inventions an iron-based shape memory alloy (Fe-SMA) fixing unit, a filling unit, a structural layer, and a test wire. A Fe-SMA having a restoration capability in the case of heating is used and formed into a honeycomb structure to greatly reduce an amplitude of fatigue stress and an influence of fatigue cracking of a welding part on the bridge deck.

Bridge systems and methods for constructing bridges having overhang surfaces employing generally rectangular, precast, prestressed concrete panels. One method includes delivering a plurality of generally rectangular, precast, prestressed concrete panels to an installation site, and delivering one or more support beams to the installation site, each support beam having a support and a base. The concrete panels are positioned on the supports of the one or more support beams with an overhang panel section and a traffic panel section. The concrete panels are then connected to the support beams by positioning steel reinforcement in block outs or voids, pouring unsolidified concrete into the voids, and curing the unsolidified concrete to form an overhang traffic surface. Bridges constructed employing the precast, prestressed concrete panels and methods. Other bridge systems employ prestressed concrete L-walls and double-T members, where weight-bearing L-walls have pockets for webs of the double-T members.

A construction module for a structure, comprising: a formwork member that includes a base, a pair of parallel side walls that extend upwardly from the base, and a pair of parallel end walls. The base, the side walls and the end walls define a cavity for reinforcement and concrete. A reinforcement member includes an upper portion and a lower portion. When the reinforcement member is located in the cavity and concrete fills the cavity, the lower portion of the reinforcement member and the concrete define an elongate beam.

A concrete deck demolition method for demolishing a concrete deck. The demolition method includes cutting two access windows into the concrete deck, installing a guide rail along a structural beam, making two tilted cuts on an upper surface of the structural beam, supporting the weight of the concrete deck utilizing an arching effect created by the geometry of the tilted cuts and lifting away a concrete deck cut portion for further demolition process.
