Lateral System for Open Structure? 2

[Lion06]

What kind of lateral system would you use for an open structure that is really just posts with a roof? This is a structure to cover a patio? It can't lean on anything.

My first thought was knee braces, but the posts are steel clad in wood. So my next thought goes to simple cantilevered columns. My only hesitation is that the footings will end up being very large for a large uplift and overturning moment.

I know there's not an easy way to get a reliable moment connection between a steel post and a glulam beam, so are cantilevered columns my only other choice?

I pucker up every time I see it coming out.

Without reading the above posts (usually a mistake) -

I believe woodworks recently did a webinar on open air structures and most of the structures used embedded pole/cantilever columns (use embedded pole calc or treat it like a soldier pile and use broms method). I can try to find the slides for it if you would like it. I don't remember if being too informative as it was more for architects.

It does not seem your loads are high enough to warrant this, but I thought I would mention the handy Simpson Strong Tie steel moment frame solution. I tried out their software package, and if the frames were a more readily available in our area, I would spec them a lot.
