A wall post is a non-structural vertical or horizontal element resembling a column or beam, but with a different function. It is used to connect walls to columns, beams, or concrete slabs and secure them. Essentially, a wall post serves as a type of bracket. The purpose of implementing a wall post in a building is to transfer loads resulting from wind and seismic forces to the structural frames and to reinforce walls against collapse. Essentially, the wall post serves as a support system during construction and helps prevent wall destruction during earthquakes by bracing and anchoring the walls.
