9.2.3 Load Path at Pile Caps
The pile caps are capable of transferring overturning and lateral forces between the structure and individual piles in the pile cap.
The deficiency is insufficient capacity of the pile cap to transfer seismic forces from the superstructure to the individual piles. Check the moment and shear capacity to transfer uplift and lateral forces from the point of application on the pile cap to each pile. Conforming buildings which fail this check shall be placed in SPC 4.
