Composite (ie Trex) Decking and Lateral Loads
Composite (ie Trex) Decking and Lateral Loads
(OP)
I was wondering what you are all doing when you design a deck as a cantilevered horizontal diaphragm but using composite decking? The ESR report for Trex specifically says it may not be used as a diaphragm (section 5.1). Am I misinterpreting the ESR report when it states "Trex must not be used as a component of trusses or structural diaphragms..."? Are you placing some type of horizontal bracing under the joists or decking? Sheathing perhaps?

Don't know why you are using Trex decking. They went extinct 90 million years ago.

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.
