Hello Everyone,
I have a project where there is a requirement to hydrodem part of a concrete structure to a depth of 4in - section is approx 4ft thick. What I am wondering is if there is a good way to visually see how much has been demolished. I am thinking of something like a marker that...
Hi all,
How does one consider creep and shrinkage in analysis of a structural element? For example, do you actually check different design stages by adding the strains due to shrinkage and creep to the strains present in the section from loading to increase the stresses?
So, for the long...
Hi Chaps,
I've designed a corbel supporting a pcc beam using the strut and tie method to calculate the reinforcement requirements.
Any thoughts on checking service conditions in RC corbels- for cracking at the face of the tension tie based on the area of concrete?
I'm not sure this is...
Hi,
I'm undertaking a design check for a large 12m diameter cover slab. The slab has a number of large openings(2.9 x 2m the largest).
What I'm not sure about is how to determine the reinforcement at the corners of these openings, I see the practice is to provide diagonal bars but I'm not...
Hi all,
It's been proposed on a project I'm working on to land the base plate for a new steel structure onto an existing masonry abutment and connect in to the abutment by drilling into to the masonry, grouting in a dowel connection and the tensioning the bar after the base plate is installed...
The challenge I'm facing is finding a sensible bracing member/ connection design for a 30m span steel bridge. We have an FEA model of the structure with the bracing members modelled as line beams with end releases(pinned). The thermal loading from -20 to +40 degrees celsius is applied to the...
Hi all,
I've attached a sketch regarding this detail, it's a T-stiffener welded to the underside of the steel deck plate of a bridge. The structure is a rail bridge so I've calculated the stresses in the section due to the live loading(LM71) and I am treating 0 live load as the minimum for the...
Hi chaps,
I've been tasked with looking at the effect of an accidental impact on a replacement bridge we're designing(the new design does not meet the clearance over footways). I've been searching the eurocode and it seems to me that accidental actions are always taken as with a partial factor...
Hi Chaps,
I'm looking for tips on RC circular section design to EC2, in particular, design for rc piles. Any worked examples would be great.
Thanks and regards

Hi,
I'm struggling with finding a suitable method to check the embedment of a pole in post mix concrete in the ground supporting a 2.3w x 1.5h m sign board.
I'm just doing this as a hand calculation. The pole is embedded 1m below ground level surrounded by 0.3m^2 in plan block of concrete...
I work at a UK company and I've been asked to come up with some calculations for a simple timber truss structure supporting a sign. I've done the majority of this, sizing the timber, checking permissible stress etc. I've built a few things from timber and I know for burying it in the ground...
