When the pillar shares nodes with the deck using Shared Topology, deformations in the deck and the pillar create high stresses at the base of the pillar.

When the foot of the pillar becomes a Fixed Boundary Condition, the deformation in the deck is also zero at that edge so the deformation and stress at the base of the pillar is much lowered.
