RE: FLAG POLE FOUNDATIONS in CA

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Anyone have any suggestions regarding the design of a flag pole foundation? I have several manufacturer's catalogs with ground sleeve installation details but I don't have experience with this... (do these ground sleeve details typically meet the requirements for UBC 1997 Section 1806.8.2.1 Non-constrained)? Here are the design criteria:
Location: Riverside CA
Height: 33'-0" nominal
Butt dia: 6"
Tip dia: 3.5"
Wall thickness: 0.188"
Windspeed w/flag: 100mph with 2.5 s.f.
Windspeed w/o flag: 170 with 2.5 s.f.
Cone tapered round pole
External Halyard
Hand Crank.
