It's a pre-engineered system designed per OSHA for a 200 lb. load. The wind load on 10' section is less than the 200 lbs. (around 120 lbs.), but it appears that the railing section counts on adjacent sections to support it when subjected to a 200 lb. load. The wind load acts on all sections at once. The client asked us to look at the systems performance with regard to wind loading. As of now, I'm using 0.7, but looking for opinions.
Eric - Depends on duration of temporary, but, in my opinion, winding loading should be looked at for temporary structures. In this case, it will be approaching permanent installation.
