Perhaps my terminology was off, but yeah, you use the bending in the beam to stabilise the structure and the diagonal member takes the compression that comes as a result of any horizontal loading. Tension in the vertical member, therefore - as you said you get a 'weird moment' in the top member.
The brace is the diagonal member at the end.
But yeah, that is exactly the kind of info that I'm looking for. Where did it come from?!! Why isn't it printed in every structural steel document ever?!!
How do you go about calculating the horizontal deflection in a braced structure by hand? Sorry if this seems a really dense question - I've never had to calculate it by hand before but I can't get a FEM model to work properly and I'm confused.
I have attached a picture of the problem ->...
G'day chaps.
My senior is looking to reference a design guide to give credence to a 50 year design life statement in one of our bid submissions.
Is there anywhere which states in the British Standards how long the design life of a structure should be if designed to BS5950 or BS8110?
Strange...
Architect isn't shifting on this one, apparently.. He insists that the detail has been used before and that it is perfectly workable. I, like you chaps, have my reservations.
Cheers for your views, chaps. Much appreciated.
Correct, countervail!
I found some guidance on the use of stainless steel rebar eventually but it doesn't provide any numerical answers. Just that 'you can probably reduce cover if the workmanship shouldn't be a problem' or words to that effect.
I'm looking at a swimming pool design in the UK and the architect wants the steps into the pool to be built into the concrete pool wall.
There is a requirement for a minimum cover to reinforcement in swimming pools to the British Design codes of 40mm but if we use stainless steel reinforcement...
I have some non-standard sections that I am trying to use in a model however I need to work out the torsional properties of the members and am having trouble finding an accurate way of calculating them either by hand or by computational methods (without trying to get my director to shell out on...
I'd have to disagree for the most part on my 'lack of understanding' but I appreciate your input, thank you.
I have since resolved this issue, however what I was really trying to get at is - why does the software allow you to change the effective width of the beam in question if in reality the...
I'm working with a modelling program called Building Designer and I've been playing with some of the factors to give myself an efficient design.
When looking into a particularly heavily loaded building I've noticed an issue regarding balancing getting the required number of shear connectors for...
DRG, you're bang on the money. It was my diagram last time though I'm asking a slightly different question this time. I must admit, geotechnics is not my strong point but that seems to be the only work available in the office at the minute so I'm trying to get my head around this stuff.
Cheers...
I suppose this 'arching' I'm concerned about is sort of like the effect produced in silos or the backfill of trenches over pipes where you get relief of pressure due to the specific settlement in soils.
Is there anything else you can tell me that might help me out? I don't think the mid term...
I was asked to look at the potential for some rough (100mm down) backfill material to arch against a revetment and a quarry face (I've even drawn you a little diagram).

Do you think this is plausible depending on the height of the fill and if so...
I believe there may well be a wire mesh diaphragm every 3m lift. I'm not sure though...
I'm not too interested into trying to stabilise the BES until I am sure that there will be a problem with it. Do you think there is a realistic probability that the backfill will cause an issue such as the...
I've been asked to have a look at a landfill project as pictured in the link to check if the design will be stable for a different use other than the purpose it was originally designed for.
