On Saturday 21st March 2015, the annual Irish Concrete Society Awards took place and Shay Murtagh Precast were announced as Winners of the 3rd International Award “Reading Elevated Platform Viaduct”.
This week Steve details the other applications of precast concrete culverts. Examples include structures such as UAN and portal frames.
This week, Steve takes a look at the different ways to optimise box culvert design such as exposure class, cover to reinforcement and the detail of waterproofing. Also the use of high-grade high strength concrete and its effect on stress limit checks.
This week, Steve explains the basic load requirement to design a box culvert – Self weight of precast box culvert, vertical weight such as fill as most box culverts are buried and earth pressure. He briefly explains vehicular, pedestrian loads including braking or tracking load detail.
This week, Steve explains national annex and eurocode detail used to design precast concrete box culverts at Shay Murtagh Precast.
This week, Steve explains the typical steps in design of precast concrete box culverts by variance in application, relevant code and details fundamental steps, defining load and its effects, define of reinforcement and thickness of slab and walls.
Steve explains the purpose of a box culvert’s joints, involving sheer connection and project transportation. He also details the differential settlement on installation and sealant.
This week, Steve explains design purpose of precast concrete box culverts. He details load transfer including vertical load, earth and bearing pressure.
