STAAD query for AISC code check (Eq.H3-8)

(Hello, Sir

I am using the AISC 360-10 code to design the Angle section tower in STAAD.Pro.

In my model, one member failed to check for clause Eq. H 3-8, but the design force is very small.

So I want to know why it is failed?

I have uploaded the model, please check the member 414.

Thanks!
