Foundations permitted to rock beyond 2 uplift limit or exceed ultimate bearing stress and a linear stress distribution

OANR: Use 2 uplift and linear stress distribution n a

More than the outer line of piles in group systems allowed to plunge or uplift under seismic loadings

OANR: Only outer line is permitted to reach tension capacity

Plumb piles that are not capacity-protected (e.g., integral abutment piles or pile-supported seat abutments that are not fused transversely)

OANR: Use seat abutment or a detail that allows movement

Batter pile systems in which the geotechnical capacities and/or in-ground hinging define the plastic mechanisms

OANR: Plastic hinging forced to occur above ground in column

Isolation gap optional
