Anyone got the picture showing the supports at parkhead when the games not on? Tarrier doesn't believe me that they use them

Im sure its vibrations when the stand is occupied causing movement to the roof

It's something to do with the weight of people in stand secures it, not 100% sure of the ins and outs.

I'm a structural engineer and at my first company I noticed a model of a stand in the office one day, so I asked what it was for. My boss told me that he had been the expert witness in a court case where Celtic had sued the designer of the main stand.

The design company made a few mistakes, and after the stand was opened it was noticed that it swayed a lot in the wind. My boss was then commissioned to perform an independent design check of the stand. He found that under the design wind loading the stand was basically a mechanism if it was unoccupied, i.e. the empty stand would fall over if the wind speed got up to the figure that the stand should have been designed for, but during matches the fans would act as ballast to provide enough stability.

It was decided that props would be required to stabilise the whole thing but Celtic wanted to avoid restricted views from their brand new stand, so my boss reluctantly agreed that temporary props could be removed just before matches and reinstated after the crowd had gone home.

I've stopped going to the piggery in the last few years because the last time I was there and the bears were doing the bouncy, I genuinely thought the stand was going to come down!
It just wasn't right for a structure to move that much.

They sued Redpath Dorman Long (Cambuslang) which was part of the British Steel Corporation.

Many of my mates worked in Redpaths at the time and I don't believe they put their heart and soul into this particular project.

The Kerryfail bunch were claiming recently that the Ibrox main stand was build over mine shafts or somesuch and that the subsidence was deemed to be "significant". Sounded like a pile of pish to me, but can anyone confirm one way or the other?

Part true

The bit about the fans acting as ballast is an urban myth
The fans are sitting on a ground bearing structure feck all to do with the roof

The columns are there to hold the roof down on windy days
Thats why you sometimes see them down during match days
They had to cut 600mm of them when they added the press box

I was told they are always to be in place, except during matches. I've never noticed them still up during any match, and surely they wouldn't deny their existence if the props are still in place during some games.

The reason for them is to provide stability during extreme wind, and you normally design for horizontal wind at the same time as vertical wind (uplift or downdrag). Therefore what you've been told (about holding the roof down) is only part of the story.

I don't understand why they would cut 600mm off them when they added the press box, as they wouldn't work afterwards.

The collapse of the Tacoma Narrows was caused by strong winds.

Yeah, it was to do with the natural frequency of the structure. Every structure has its own natural frequency and if load is applied to it (the loads don't even have to be too excessive) at the same frequency it can collapse.

At Tacoma Narrows the wind was buffering the bridge deck near its natural frequency, and it collapsed as a result.

When soldiers march across a bridge their steps can be close to the natural frequency and a few smaller bridges, mainly temporary Bailey bridges that had been installed by the Royal Engineers, did collapse in the past due to this. That's why it is traditional for marching solders to be ordered to break-step while crossing bridges, so that they're not all marching at the same frequency.

It was the same problem which affected the Millennium Bridge in London.

It will be nice to get back to talking about football next week rather than what I do 5 days a week at work .

It's not a natural frequency problem with that structure, it's just a case of the wind speed at the San Giro. Their main stand is a fairly exposed structure though, given the lack of other buildings around it.

As someone who thought Applied Mechanics lessons were a waste of time but now runs a small construction company your input is both educational and welcome. It's embarrassing when your structural engineer has to use a highlight pen on the calcs to ensure I buy the right size steels and don't get confused by all the numbers on the page:o

I remember a few years ago the BBC billed them for camera cables that were damaged by rats eating through them, from what i remember the cables were laid around the pitch and left there through the season to make it easy for cameras to be installed on match days

apparently some resident rodents found them a tastier option than the pies on offer....
