Questions in 9.0 FOUNDATIONS AND ANCHORAGES
- I’m trying to determine if a pad & pier should use a phi of 0.75 on the resisting moment to resist overturning. Mult/(Phi*Mrest)I believe it is the intent of the TIA to say this (per 9.4) but it is not explicit.If the phi is to be included in the overturning calculation; Then does it apply to the entire resisting moment or just the portion derived from the soil (as opposed to the foundation weight or axial weight?
(282651 views) - Section 9.6 What is the intent of the grade beam, similar device, or other approved method to resist a portion of the base seismic shear? Is it to resist differential foundation displacements during a seismic event, to resist the effects of liquefaction, or both? If differential displacements is a concern, what is the allowable displacement? Does the same force requirement (2/3 of the total base shear) apply for 3-legged and 4-legged structures alike?
