[per IBC 2009 Section 1807.3.2.1] <br /> 2 Constrained: Constraint is provided at the ground surface, such as a rigid floor or rigid <br /> ground surface pavement. [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 cons deration, IBC 2009 Section 1806.3.4 <br /> permits a 100% increase in lateral bearing pressure. -iKp, Additionally, an increase in-/Kp 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 /> • Backfit Requirements: See IBC Section 2009 1807.3.3 for backfill requirements at pole foundations. <br /> show r. <br /> Ansted <br /> COFFMAN �"° <br /> 04/0 N G k E R S a°"' Boeing Flightline Stall 113 crocked Page 15 <br /> data <br />
