Open web joists shoring
(OP)
Hi guys,
Contractor has sent me these drawings recently.(see attached some print screens) They are going to replace a roof truss which holds all the roof joists that go perpendicularly and they call out for temporary shoring to support these open web joists. They propose 2 x W beams going parallel to the truss. I am ok with that, but my concern is - shouldn't they support the top flange of those open web joists instead of supporting them at the bottom ? Once the bottom flange is supported, the whole reaction would go to the cross which is in compression instead of going to the first one at the support which would be in tension - and that can cause a problem.. I am not sure though, any advices with an explanation will be much appreciated. Thanks folks!

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
