Connection of deck guardrail posts
Connection of deck guardrail posts
(OP)
Hello,
Anyone has a detail for connecting guardrail posts to a flush beam at the edge of the deck framing with the post on top of the beam? The connection must be able to resist the 200# load at the top

With the post on top of the beam - you'd almost have to fabricate a custom bracket of some sort to create the necessary moment connection.

It looks good when the force is applied to the left, relative to the detail. The tension tie acts in tension. But when the load is reversed, the bottom bolt is in tension and is just all by its lonesome down there with no tension tie to help it out.

As for the OP, I have done both the knife plate (with a 4x6 posts) and straps details.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

Jittles: I believe the concept is that since the posts are at edges of decks, the 200# load will not occur in both directions unless something comes flying from the outside to push that post towards the deck. I also was told by contractors that using a HDU2 is cheaper than the DTT2Z bracket.

Doesn't always stick, but I love having it to point to with the client. You can pay twice, but just don't blame me...

"Do the Simpson Strong-Tie
details address load applied in all directions?
The details in this technical bulletin address an outward force
on the guardrail. An additional connector can be installed on
the lower bolt to resist an inward force."
So the detail is not code (IBC/IRC) compliant.

So just write me off as a dumb engineer who wants to design per the code as the public has selected it.
