large bending moments would develop at the pilehead, in excess of 12MNm for a
dislocation of 2m. The middle row of piles would experience much less distress,
but the last row and especially the corner piles would develop substantial bending
moments (almost 6MNm for a dislocation of 2m), as a result of being “pushed”
