“…Initially, the honeycomb composites and, later, the structural foams, as polyvinyl chloride (PVC) or polyurethane (PUR) as well as balsa wood, have been used for cores in sandwich systems. These systems are increasingly used in construction, where high flexural stiffness and strength combined with low weight is required, and recently have also become an emerging and effective alternative for new and rehabilitated bridges worldwide [9–11]. Because of the low stress levels at which FRP structures operate, governed by stiffness criteria, they are practically insensitive to fatigue.…”

The paper presents the selected research results on the development of a novel fibre-reinforced polymer sandwich decking system dedicated for bridge applications and applied in the first Polish all-composite vehicular bridge. Based on a review of recently implemented similar systems, the novel solution has been proposed and checked according to relevant codes as a part of all-composite bridge design. Due to the novelty of sandwich design, the comprehensive structural testing has been carried out to verify design assumptions as well as to assess its stiffness, strength and safety. In order to find the optimized structural solution of fibre-reinforced polymer deck, the laboratory tests were conducted on several FRP sandwich panels having various core foam density and internal ribs’ fabric architecture. The panels were subjected to three loading schemes to check their response under bending, shear and bearing as well as to examine their structural behaviour up to failure and corresponding failure modes. The stiffness, strength and safety against failure were experimentally determined. In this paper, the test results have been compared to the ultimate and serviceability limit state design criteria formulated in the European guidelines and applied in an actual bridge design.

“…Finally, in the third stage, the material properties of the GFRP laminates composed of different glass plies tested in the second stage were experimentally determined. Thus, the sequential design by testing was carried out to obtain “tailor-made” material properties, as required in FRP bridge deck panels [ 15 , 16 , 27 , 28 ]. Subsequently, micromechanical calculations were performed to determine analytically the same set of material properties to be compared and validated against the test results.…”

This paper presents an experimental material campaign focusing on fiber-reinforced polymers (FRP) to be applied in a novel bridge deck panel. Laminas based on most commonly used fibers, i.e., glass, carbon, basalt and aramid, were prepared and studied in tension, shear and compression. In the subsequent test stages, different fabric reinforcements (uni- and bi-directional fabrics, woven fabrics, CSM layers) were considered for glass laminas only, and finally, a resultant laminate was designed and tested. Such an approach gives a great opportunity to create “tailor-made” laminates, as required in FRP bridge deck panels. Simultaneously with the laboratory tests, analytical calculations were performed using a few micromechanical models that aimed to determine engineering constants and strength parameters. Then, the results obtained from material testing and analytical calculations were compared, and conclusions on the compliance were drawn. Based on this validation, further analytical calculations may replace time-consuming laboratory tests and facilitate FRP deck design.

“…Review papers, such as the one presented by Mara and Haghani (2015), are particularly useful to practicing bridge engineers as they provide a single point of reference giving the background and current state of application of a developing material or construction method. This comprehensive paper on the structural application and in-service performance of fibre-reinforced polymer (FRP) bridge decks provides an extensive review of available structural forms of FRP, a description of how these have been applied for bridge deck construction and repair, and what failure modes the material needs to be designed to resist.…”

We know that bridge engineering requires a wide range of skills and knowledge. It is a given that an advanced knowledge of structural form and analysis is required. However, bridge engineers also need to be aware of the diverse range of current practice and developments around the world. They need to keep abreast of the latest research and how this might be applied to improve both their design of new bridges and management of existing bridges. Of course, knowledge of innovative and feasible methods for construction is essential. They also need to be informed in the latest developments in construction materials. It is equally important to understand how existing bridge designs behave and what techniques are available to monitor this behaviour. Finally, the bridge engineer needs to have a historical perspective in order to understand why their predecessors chose the structural designs and applied the construction methods that were applied to create the existing stock of bridges.This issue of Bridge Engineering includes six technical papers that cover all of the above diverse aspects of bridge engineering. The geographic spread of the authors contributing to this issue clearly demonstrates the truly international nature of bridge engineering as well as the readership of the ICE Proceedings.In the first paper, Donnelly and Wise (2015) describe the design and construction of the South Highway Superway project in Adelaide, South Australia. This 4·8 km-long highway scheme includes 2·8 km of elevated viaducts. The balanced cantilever method is employed to construct the match cast concrete segmental deck through a very tight site corridor. A particularly interesting feature of this design is the use of steel needle beam expansion joints that eliminate the need for large bearings below the deck. This development should yield long-term benefits for reduced maintenance costs.The distribution of patch loading applied to bridge decks onto adjacent supports, such as wheel loads on highway bridges, is an area where bridge engineers have always had to apply engineering judgement. In the second paper, Lantsoght et al. (2015) investigate both an approximate spreadsheet method and a more rigorous numerical analysis using a linear finite element method, based on Dutch practice. Results are compared to experimental measurements and they are able to conclude that the peak shear stress at the support can be distributed over an easy to apply width of four effective depths of the slab.
