The design of this innovative Precast Concrete Viaduct Bridge structure known on M50 Upgrade Contract as ‘Structure 17’ is a large curved viaduct bridge spans over a live railway, canal and existing N3 dual carriageway. This structure will ensure free flow of traffic east bound on N3 to access the M50 Motorway South bound. Main […]
Concrete Bridge Deck Supplied by Shay Murtagh. The bridge is a two span cable stayed structure over the River Moy. The main span is 47m and the side span 21m. The 25m high curved pylon is a fabricated steel box section clad in GRP and sits on an in-situ concrete pier in the river. Precast […]
This week, Steve explains different aspects which aid optimisation of pre-stressed bridge beam design such as high strength concrete, de-bonding and exposure class. He explains crack width checks effect on such design and where applies.
This week, Steve explains the design codes used by Shay Murtagh Precast in designing prestressed concrete bridge beams – Eurocodes and British Standard and related annexes.
In this weeks video, Steve explains the typical steps to bridge beam design involving structure definition, load and load effect, strand and links layout, stress and sheer limit checks.
In this weeks video, Steve explains the benefits of high strength concrete based on stress limit check in design and what the function of the grade of the concrete brings to design, span, and strength of bridge or other beams.
As blogged late last year we are uploading a series of 12 video blogs about Bridge and Culvert Design. This week Steve Lowe, our Senior Design Engineer will be discussing how a prestressed concrete bridge beam works.
A project completed this summer was Gas Works Access Bridge for BAM Nuttall Ltd. They awarded Shay Murtagh Precast with the manufacture of the concrete bridge beams for this extension to a bridge in Chelsea Harbour, London.
Introduction to Cross Rail Project Cross Rail, one of the largest projects currently in construction in the UK and Europe is due to open in 2018/19. Morgan Sindall secured the C350 Crossrail Pudding Mill Lane project which includes as part of its remit a six span viaduct to carry track for the Docklands Light Railway. […]
Shay Murtagh Precast manufactured and delivered the precast units and precast bridge beams required for this project. Network Rail’s vision for faster, more frequent rail services between the region’s main cities. As well as plans to electrify the railway between Manchester, Liverpool, Huyton and Wigan commenced work in early January 2012.
