I really don't get where this keeps coming from.

This was not a contributing factor cited by the Linbeck group or the FEMA case study later on.

It's also not accurate. Stack heights fell in line with their normal range.

I understand that it had worked for a long time with the wire but I really don't understand how they couldn't have decided serious cable wasn't better? Was it an aesthetic thing where they didn't want it seen? It wouldn't have taken much of it to secure a layer of the stack and there's no way it would have given without some high temps and by that time it wouldn't have mattered right?

I just hate the fact that something that cool is now gone. Not that I love aggies but I doubt they'd want us to not bring Mike on the field. It's an SEC thing. Or it should be. frick Texas.

Wasn't there it's just what I remrmber reading and it's the way my cousin who was there and injured described it to me. If it's inaccurate I apologize.

There was a reason cabling hadn't been put on yet that didn't have anything to do with structural stability. Won't say more than that but it was an intentional choice.

Ultimately though even with the cabling, the report found the structure was unsound, ie there's a good chance this could have happened eventually even with the cables in place.

The off-campus Bonfire they have today doesn't have any logs stacked on top of each other like it did in the past - each log touches the ground. It's still a large undertaking but it's far far safer.

Are you referring to just the height of the second stack? Because the width was definitely a problem.

The Linbeck Report identified "overbuilding," the building out of the second stack too closely to the perimeter of the first, as a causal factor. It's just another variable that increased the hoop stress on the lower stack.

However it was not a primary cause.

The report did not find this. It found that the cables in past years "dramatically" increased hoop strength and that their use would have "greatly" decreased the likelihood of a collapse.

However it wouldn't have solved the wedging, vertical log, sloping, or overbuilding effects.

The absence of cables was a ultimately listed as a primary factor in Linbeck's report.

See page 18.

I thought that's what I remembered reading but wasn't sure. I know what my cousin told me and that's what I repeated

In the end the biggest issue was you had a bunch of college students, most of which were not remotely Civil Engineers, in charge of the design and implementation of the project. I believe there had been an engineer in the '80s that improved the "Wedding Cake" design but for some reason they strayed from that little bit year by year.

There was no ill intent of course but it was highly irresponsible for there not to be at least someone with a real Civil Engineering background checking the stack during construction. I know the liability would have been difficult but a school with massive Civil Engineering and Building Construction schools they should have found a way. I know I thought they did when I worked on it years before it collapsed. They just got lax about it and the results were tragic, the sad thing is there were a dozen different ways it could have been prevented but no one saw it coming.
