Could have been dodgy builders.

 

Or inferior materials.

 

You mean it was like, a Tescos Value roof?

"A few less bricks, but almost as good"

 

Tesco! Greedy *******!!!!

I remember when they opened one in Bangor North Wales, it was only open for about 8 months and they decided to knock it down and build an Tesco Extra!! While it was being built they erected a mahoosive marquee in the car park so they could carry on selling!!!! I used to carry Slate Waste from the quarry there for the foundations. £250,000 the foundation cost them alone!!!!!

They execute architects for that sort of thing in Russia!

Les

 

It certainly was not kosher.

 

That was one halal of a close shave

 

Why would they execute an architect for a structural failure, do they not have structural engineers in Russia?

 

Yes, but its still more productive to execute the architects

Looking at the Daily Mail photo the column nearest the camera has remained upright, the four behind have all bent at the base. So the head of the columns was subject to a horizontal load for which they were not designed. Snow would be expected to be carried vertically.

My guess is that the snow slid down the roof, then got stopped by something like the gutter or a small parapet or the signs in photo 3, putting a lateral load on the columns which then failed. That is going to take a lot to repair / rebuild.

The column nearest the camera has remained vertical and punched through the roof, so its like a separate failure due to snow load, probably aggravated by the unexpected motion in the structure.

 

Always seems to be reported that the architect gets it.

Interesting...I wouldn't be suprised if one of the chs supports (Y) had buckled under the dead load of the snow resulting in the failure of several others.
Architects do like circular hollow sections as they are more pleasing on the eye....not in this case though

 

It's defo made Asda and Morrisons day

We went past Morrisons earlier to go to her mum & dads. A18 weas gridlocked all the way down (in one lane ). Went to Asdas later in the day and there were old boy trolley collectors looking out for parking spaces it was that rammed

Tesco is defo shut today

 

Aye, poor old Tossco! Couldn't have happened to a nicer store, LOL

 

Did you pop along to Bangor exhaust centre too?

 

Update please.

Is the store open and trading normally, or have they announced that it will be closed until after Christmas? Is there a lot of heavy duty scaffolding being deployed?

 

By any chance do you work for Morrisons?

Chris.

 

Yea, look for the really old chap collecting trolleys from the car park.

 

That really old chap fixed my leaking pipes so leave him alone you meany!

 

why does no-one like Tesco ?

 

The Morrisons stores here in North Wales looks fantastic, nice brick work etc etc. Safeway did a good job fair play to them

 

re-opening to the public saturday morning. As to scaffolding, not been down, will ask around.
it being Tossco and North Lincs, (Martini*) council, there will be "no problem".

*Martini: build owt you like, any place any time.

 

So did the store re-open?

 

Apparently open yesterday morning.
They have been alowed to clear their carpark of snow and dump it blocking public footpaths.
See what I mean about a Martini Council?

 

I think it actually makes a nice curved feature, they should keep it

 

i'll see your tesco and raise you the metrodome

I was thinking that myself,when i first looked at the pic i thought where has the roof collapsed then .I thought the curved or sloping feature was part of the design...

 

looks to me like the corner colum failed and pulled the rest of it down, but i can;t tell properly form the limited pics.

as far as failure, could be any number of reasons, from a physical failure of the structural members, to overloading byt he snow and ice.

 

The mail had a better pic. One of the pillars had concertinaed, and one had punched through the roof, the others had been pushed over at their bases.

Newer Tesco's have oval shaped pillars, maybe stronger?

And this isn't a single incident: there have been other Tesco roof collapses.

 

no not stonger, take a piece of paper roll it up and stand on the end, i bet it would support alot more than you think. Loadings wise it should have been design for snow loading anyway.

does sound like it became overloaded, weakest part failed and then rest went with.

could be a failure of the colmun due to age (unlikley), loading capacity (snow weight), condition (if water's got at the steel it will rust heavily and reduce its capacity in that rust area, may have been struck by a car and chipped the paint) etc etc.

without being on site to see its just speculation.

They don't build em like they used to, i surveyed a bridge circa 150 yers olda number of years back (anyone in nottingham will prob have driven or walked over this bridge) and the top 30mm of the main support beam top flange was rusted completely and just crumbled, with the flange being 130mm thick it was way over designed so not an issue. modern designs don;t have that level of tolerance.
