I'm reading the 2015 IBC Section 1810.3.11.2 which states:
"For structures assigned to Seismic Design Category D, E or F, deep foundation element resistance to uplift forces or rotational restraint shall be provided by anchorage into the pile cap, designed considering the combined effect of axial forces due to uplift and bending moments due to fixity to the pile cap."
Does this imply that pin-headed piles are out of the question for high Seismic Design Categories? Must rotational restraint be provided? Or is it implying that if rotational restraint is provided it must be properly considered? Seems like poor wording.
