‘FlexiArch’: Rapid method of constructing arches
Abstract eng: Arch bridges are strong, durable, aesthetically pleasing and require little maintenance but very few have been built since the early 1900’s. However, there has been a mini renaissance of this proven form of construction since the FlexiArch was launched in 2007 as it uses precast concrete voussoirs, has no corrodible reinforcement, does not need centring, can be installed in hours and is contractor friendly. After installation the FlexiArch system acts like a traditional arch and not surprisingly, has been found to be exceptionally strong and stiff. To date over fifty FlexiArch bridges ranging in span from 4–16 metres have been installed in the UK/Ireland and in this paper exemplars will be given. As it is very sustainable and has very low full life cycle costs, the need for longer spans (30 metres plus), and multi-span viaducts has been recognized and solutions under development will be described.
