A wall post is a vertical or horizontal, non-structural feature that resembles a column or beam but has a different purpose. It is used to securely join walls to concrete slabs, beams, and columns. A wall post functions essentially as a kind of bracket. A wall post is used in a structure to reinforce walls against collapse and to transfer loads resulting from seismic and wind pressures to the structural frames. By bracing and anchoring the walls, the wall post essentially acts as a support system during construction and helps avoid wall disintegration during earthquakes.
