Wall

Types of walls:

Load-bearing walls: Support the weight of floors and roofs, so it is thickened to the proportion of the forces it was to resist. Lateral forces of arches, valts, wind, etc, may cause it to crack.

Non-bearing walls: At most support their own weight. Excluding the independent garden variety, non-bearing walls appear only when loads are carried by toher members, as in heavy timber and other skeletal structures.
