Category: Bridge Beams

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.
