RE: flag pole deflection

[Subject Prev][Subject Next][Thread Prev][Thread Next]
That is interesting.  15% is about an h/7 deflection.  That is a huge
departure from the initial take of h/100.

The 2.5% limit is for Group I loading (Dead loads or Transverse loads from 
cables).  AASHTO does not consider deflection critical for temporary loading

such as wind.  In the commentary Section 1.9.1(B), it states "For high-level

lighting (pole type) designs, deflections of 10 percent to 15 percent of the

pole height under design loads do not appear to be unreasonable."
