5. Bearing walls
Bearing walls: A bearing wall is used as a support, e.g., for the floors and roof. Usually raised on foundations, it is thicker at the bottom than at the top because loads accumulate towards the base, and is often buttressed. Its thickness is proportional to the forces that it has to resist. Doors and windows weaken the resistance of the wall and divert the forces about them to the parts on either side; these forces are transferred directly to the base of the wall. The number of openings that can be used depends on the strength of the masonry and the stresses in the wall.

9. Retaining walls
Retaining walls: A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is change in ground elevation that exceeds the angle of repose of the soil. The active pressure increases on the retaining wall proportionally from zero at the upper grade level to a maximum value at the lowest depth of the wall
