this falls into civil engineering, but as we all know everything boils back to physics. and, i couldnt find any good civil forums to join.(adsbygoogle = window.adsbygoogle || []).push({});

so, i have a basic Q but need help understanding some things.

1) i am building patio cover approx 50ft long x 14ft off the house. it has a pitch around 6 degrees.

2) i need to submit design loads. wind load is my last piece. i need to calc at 90mph. but at this low angle and low elevation (~8ft) its more like a airfoil, a very flat airfoil. what airfoil equations to use? i initially though i would calc max downforce or uplift by considering the area as a vertical plane using the UBC '97 equation force=A*Ce*Cq*Qs, but this may yield way more force than i need to account for.

any ideas here?
