<p>This paper describes the structure of a weathering steel footbridge with a GFRP deck, as part of a larger redevelopment of a former industrial area in the City of Bocholt - KuBAaI.</p><p>In the recent past, the requirements on the design of footbridges regarding economic design in combination with architecture, especially in urban developments with limited budget of local authorities have increased. It is the challenge of the engineering process to explore fitting solutions to meet these requirements.</p><p>The footbridge in the KubAaI follows the chosen design concept of a low maintenance bridge by the use of appropriate materials, such as weathering steel for the main steel structure and GFRP elements for the bridge deck, and an aesthetically pleasing appearance. The structure will blend into the industrial surroundings and be much more than a mere connection, it is also a public space.</p>
The original article presented a summary of the results and conclusions of a Comparative Test conducted within the scope of RILEM TC 189-NEC ''Non destructive Evaluation of the Concrete Cover''. The Comparative Test (CT) was intended to assess, under the same conditions, the performance of different non-destructive test (NDT) methods 2 Curing and pre-conditioning of the slabs All slabs were initially stored in a moist room (20°C, 90% RH) for 24 h. Subsequently they were demoulded and treated as detailed below. *This document has been prepared by R. Torrent chairman of the RILEM TC 189-NEC Committee that consists of 26 members representing 12 countries.
<p>Arup had been commissioned with the design of a new modular bridge system by Straßen.NRW, the road authority of Germany’s biggest state North Rhine-Westphalia. This article describes the background of this pilot project, the design concept, as well as the structural design and construction sequence of two new bridges, which can be erected within 8-10 weeks. The design is characterized by a high degree of prefabrication, modularity as well as the use of high performance concrete to ensure an excellent durability. The bridges are designed as integral frames – spanning about up to 30 m. The use of in-situ concrete had been kept to a minimum. The structures contain no bearings, no expansion joints and no separate parapets, which significantly reduces lifecycle costs. The use of high performance concrete made an additional waterproofing layer obsolete, which also saves construction time. The bridges are designed for replacement of deficient structures. To minimize demolition time, the foundations were designed so the existing foundations could remain in place.</p>
The small city of Bocholt owns a former industrial area of 25 ha which will be restructured to an urban and cultural district for people to work, live and explore. As part of the new urban development four footbridges with a span of up to 47 m have been designed to connect the two parts of this area which are separated by the river Aa. The bridges form the starting point for the future development and spaces for public events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
