Diaphragm Drag Struts Perpendicular to OWSJ 1

[r-struct]

I am trying to design some drag struts around a floor opening that will run perpendicular to OWSJs. Anyone here who would be willing to share a detail that they have used in the past?

Thank you in advance.

Perhaps provide some further meaningful information, like the forces involved, what load cases do the drag forces originate from, provide the opening geometry (1/10/100/1000/10000mm holes, who knows), where forces are dragging to and from in relation to the opening(s).

Providing your guess/take on the details required will help stimulate discussion, and show that you have at least tried to think about the issue and come up against some specific barriers/further questions that you might not know the answer to.

Try draw the strut and tie diagram and resolve the forces involved as a starting point, provide reinforcement and detailing to resist the calculated forces.

1) For floors, I often find it easiest to utilize rebar placed in the concrete topping.

2) Without using rebar, I've often used channels laid flat as the strut/chord. Make the channel wide enough that you can be confident that the deck flute troughs will touch down on the channel convincingly enough to get a good weld/fastener installed in there. C8 works for the deck profiles that I typically use.

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.
