Storm Damage - Missing Wall Ties?

shane6977

Was checking out some photos of storm damage on the independent.ie website, looks like no wall ties in the linked images?

It's possible that they may have sheared off, but I would expect to see regular fixings (or the remnants of fixings) in the concrete inner leaf.

Thoughts anyone?

Thats also the 1st thought I had when I saw that damage.
Where are the wall ties?
And if they were there, what sort of shearing force would cause that type of catastrophic failure across so many of them?

From what I can make out in the picture it looks like a mass concrete inner leaf.
I this is the case I would imagine that drill in wall ties were used.
This would explain why they probably all pulled out with the brickwork as it fell.

That may be the case, but, wouldn't the holes be visible at the standard 900crs horizontally, 450crs vertically and 225 vertically around openings.

The concrete should be pock-marked with the holes from the fixings.

Hard to see as I'm viewing on iPhone.
Could also just be shot in L-ties with a Hilti gun which wouldn't hold much anyhow.
Or worse case scenario and probably most obvious answer is lazy Bricklayers and no ties whatsoever!
