Wind load on Banner directly mounted to an external wall

[ypo5yy57j77]

Is there any reduction on wind load on the fabric when it is sucked out of the wall.

The banner is tied to the wall at top & bottom and is more than 15 m high x 20 m.

CAUTION! Cyclic wind loads will induce considerable levels of dynamic loading on your banner and potentially loosen your fasteners. In direct answer to your question, in my opinion no. In fact, I tend to over-design the connections because of the dynamic action you don't get with rigid structural member signs. Just ensure your fasteners can take repeated dynamic loading.
