Bit of a long one.
I have a 14x story historic brick tower (about 11mx11m in plan and 52m high) where sulphates in the brick have eaten all the cement within the mortar beds, it’s basically just a very large stack bricks bedded on sand bands now.
Water has got into the structure and caused...
Hi
I have shelf angles supporting a set of RC stairs. I speced welded starter bars as I couldn't achieve enogth anchorage on the main bars.
The contractor left out the welded bars and now wants to cut some slots, weld in the bars and grout up. This doesn't sound to me like it would works as I...
Hopefully just a post to confirm I do know what I'm doing.
We have a project where a client has fit out a seven storey building. He now wants to pop two additional storeys on top.
We have been engaged to look at feasibility and have done some quick numbers and are happy with vertical load but...
Hi I have a query for practiceing UK engineers. How often do you carry out a search of building control records when you are altering a domestic building (loft conversion or knock out the back wall kind of a thing).
Most of the design we do is based on a site inspection and we would only...
Does anybody have experience of foundations on silt / siltstone. Or know any decent guidance.
We have a small domestic job where we will be building on silt / siltstone. We have a lot of trees on site and im wondering if silts are subject to heave and shrinkage due to trees in the same way...
We are tapping holes in a hollow section to allow us to fix in a set of bolts. Is there any guidance on how to calculate shear and tensile capacities for bolts in tapped holes?
•The wall thickness of the hollow section will be less than the nut thickness, so I would expect a reduction in...
Does anyone know of any guidance given in BS5950 (or anywhere else) about the level of deflection in struts (say horizontal roof bracing) before I have to add extra moment due to compression in the member acting a distance from the original centreline of the member.
Does anyone know how long you should wait before water testing an RC concrete pool. The pool is designed to BS8007 so reinforcement controlling the cracks is the only thing that is being used to stop it leaking.
I would like to test as soon as possible so we can “fix” any problems, but I don’t...
I have a design carried out by another engineer which I need to finish off.
We have steel trusses spanning 25m over a swimming pool. The top truss cord is braced at 2m centres by glulam purlins (eventually back to a horizontal wind truss).
The wet environment is likely to cause the glulam to...
I think I already know the answer but:
We have internal masonry walls between concrete columns. The columns are at 7.5-8m centres. We will need to provide vertical movement joints at 6m centres.
Can we design the masonry panel for flexure taking the masonry on the others side of the movement...
