Tying in Gable panel

[junglejim]

I don’t know that this needs anything extra but it was recommended by the supplier as we’re in a windy location. I’m just looking for advice on how to tie in. I’m going to take out the small brackets that were temporarily put in as will interfere with the osb but looking for suggestions of how to strap the gable into the roof structure effectively and without interfering with anything.

 Thanks

I would ask the supplier exactly what “tying in” they recommend (I am not sure what they are trying to achieve).

Surely a proper drawing exists somewhere detailing the fixings to be used?  None of those look adequate or anything like as substantial as the brackets used on ours, and specified on all the drawings.

 

The fixings of the rafters to the Glulam look inadequate to me as well as the brackets fixing the glulam to the gable.

It needs long straps by Simpson or equal.  These.

And lots of them tying the roof down to the walls. Not that the wall looks very strong either, so the ties must go down to the cross beam/ lintel and then that needs fixing down at the ends.

Someone should have specified them by type, location and fixings. Worrying that nobody seems to have done so.

Wind uplift forces are scarily high and you genuinely could lose that roof.

Do Not take any brackets off.

Thanks. Going to go back to the manufacturer & installer to see what they say but keen to strap up. If still got temporary timber ties in place so not worried about it going anywhere yet. The ridge glulam is going to be exposed so can’t strap along there where it will be exposed . I can go onto the horizontal glulam. Would welcome any advice. 
Thank you

It is the designer that should specify it, not the glulam manufacturer, they just make what is specified on the drawing.  Likewise the installers (should) do what the drawings instruct them to do.

Thanks yes will go back to the designer. Looking back at the designs I can’t see any straps specified. I’m wondering if it’s because the panel above the window is so small that it doesn’t need much and is has a structural pocket so the ridge glulam is essentially holding it together… I’d prefer something else though! The main structure is below the window and tied into the side walls and floor so not an issue. 
 

Any further advice welcome.

Can you give us a sense of scale? It may be a very heavy construction with a huge glulam and oversized rafters.

Shared some dimensions. Yes I think it’s been designed with heavier and more timbers than necessary.
