Roof pitch ,roof materials ,location ,bay crs ,height to eaves, use of building and details of side cladding and doors all information you will need to make a calculation on steel sizes. The one we will be erecting tomorrow 83 ft span 21 ft bays posts 457x191x89 rafters 457x191x67,100ft span 406x178x64 rafters ,posts 533x210x82 if less than 16ft eaves

Hi,

For shed of that size I would advise use 533 x 210 x 82kg Posts and 457 x 191 x 67kg Rafters if up to 16 foot to eaves really.

If you do require a quotation please send me details and I would be more than happy to send you a quotation out.


Many Thanks



Kind Regards

Glad its not only me that post a list of questions as a reply. I would add it also depends where in the country it is as the wind - snow loading differs. All shed should now be CE certified which should force shed suppliers to take all these points into account at the quote - initial design stage.

@Agri Design I had covered that one by asking the "location" your right sorting out all these details could save quite a lot of money on a big shed if it happens to be in a favourable location , i have seen a farm building with 20" of snow on the roof ,it does make you think

 

[Happy at it]

Cheers for the replies. Was just trying to gage the sizes needed, to see if what I was thinking on was even feasible without wasting anyone's time getting a quote. Made me realise that it's not a job to be bodged up as such and will need a designs done.

For sheds that width would there be any benefit in using posts to support the trusses if possible to reduce size of the steels or would any saving be minimal.

in that case can you do a span and lean toos

 

[Agri Design]

Best thing to do is sort out the internal layout then look at what can be done with the roof.
You can prop the steel, it can reduce things a bit but its only sensible to do if it doesn't hinder the internal layout and function of the shed. What is it a shed for? If its for stock the other thing to think about is ventilation!

Hello Brian

 

[gusbs5502]

I have seen a number of your posts. I work on behalf of a number of contractors throughout the UK who supply and erect agricultural structures. I am a member of this forum in a personnel capacity.

It appears to me that your are posting, as some others do, in contravention of the forum rules in that you are advertising the company Graham Heath Construction Ltd.

I joined this forum earlier in the year. My intention was to inform an advise the Farming Community on a pro bono basis with impartiality.

As you are promoting the company you represent in contravention of the rules perhaps you could enlighten us all to the deflection limits your Engineers and thus Graham Heath Construction Ltd are applying to the structures you supply. This, I my view would be beneficial to all, particularly if you can confirm that you are working within the Steel Construction Institute Guidelines. In particular I am interested to know what are; the eaves horizontal deflections limits, the apex deflection limits relative to the gable and the purlin deflection limits.

I’m sure that your company will have this information readily at hand. I’m also sure that as a reputable company you will embrace my view that we should provide accurate information which will enable the Farming community to make informed commercial decisions.

To all: Engineers design to basic criteria. The first is safety –this means it won’t fall down and kill people. The second is serviceability – this means that the building should not be so flexible that it jambs the doors for example and voids the warranty on the cladding – when the frame flexes it over stresses the cladding fixings, ovals the fixing holes and causes leaks in the roof.

The new amended BS 5502 Agricultural directly refers to the Eurocode and buried in the code is a statement that deflection limits should be agreed with the client ie the Farmer! If this is not explained to the Farmer who is a client just like any other client what then?

This was not made clear in the guidance issued to all Farmers following the major storms earlier in this century ie after 2000

Guss, it sounds like you have a bit of a vendetta against graham Heath if they pay for advertising then I believe they can advertise, @llamedos can advise on that.

As for all the design stuff, the op asked what size would you use, I took that as a quick question wanting a quick answer

@gusbs5502

Hello, thank you for taking an interest in advertising matters on the forum, I can assure you we have this covered in house.
If you have any concerns it is best to use the 'report' function, we find this avoids any embarrassment on the open forum.

With CE now a legal requirement for building fabricators,which has within it a requirement to prove the design( calcs) of building being supplied, the farming community can hopefully feel reassured they will get a building fit for purpose from any CE accredited supplier...of which there are many good ones to chose from.
Shop around, compare and question the designs offered and select a supplier that fits your budget and that you are confident in......simple!
Note: don't overlook the importance of groundworks and erection.......its only as good as its foundations and erection quality!

Quality remains long after price is forgotten!
