Guardrail deflection

[Chris Bernhardt]

Is it deflection or collapse that measures failure in a guardrail when someone applies a 200# load to it?

I would call it a lawsuit!

It is collapsing because it was improperly built. When an item deflects, it is moving in an outward or inward direction.

I would just say that it failed because it was improperly constructed.

Hi,

Did you not read this article and see the links in it? https://www.inspectorsjournal.com/forum ... erms=decks

Yes, I had seen the article and I just re-read it and the JLC article but I didn't see, maybe because I'm blind, any discussion on criteria of what constitutes failure to comply with the code requirement of 200#.

My question is more concerned with how much deflection is acceptable? And what if any sources can I cite? The code is not clear. It justs says resist. But what does that mean? Something deflecting is resisting. It fails to resist when it falls over.

If it deforms to the point of permanent deformity, I'd call that a failure. If it bends a bit, bounces back, and you'd think it'd keep you from falling, it's good.
