[per IBC 2009 Section 1807.3.2.2) <br /> Limitations: Pole foundations shall not be used to provide lateral support for structural or <br /> non-structural materials such as plaster, masonry or concrete unless adequate bracing is <br /> provided to limit deflections as required. <br /> Allowable Increases: The values generated by the equations above are intended to <br /> minimize movement at the ground surface. If short-term ground surface movements up to <br /> 1/2"are acceptable for the structure under consideration, IBC 2009 Section 1606,3.4 <br /> permits a 100%increase in lateral bearing pressure,-;Kp. Additionally, an increase in 7Ka of <br /> one-third is permitted when using the alternate load combinations in IBC 2009 Section <br /> 1605.3.2 that include wind and earthquake loads. <br /> • Bacicfill Requirements: See IBC Section 2009 1807.3.3 for backfill requirements at pole foundations. <br /> - br <br /> ACOFFMAN location ab <br /> NGINEERS danllob <br /> no <br /> 04/0 Boeing Fliahtline Stall 113 �«*� Page 13 <br /> Oats <br />
