TABLE 6.6 Typology of Rural Houses of Iran

Type 1: Adobe walls with
wooden flat roofs
Location: Very popular,
usually found in mountainous
areas of north eastern and north
western Iran. It is the dominant
type of rural construction in
Khorasan, Azerbaijan, and
Ardebil.
Description: Poor beam to
wall, beam to column (in
balconies) and wall to wall
connections; no longitudinal or
transverse anchorage at
bearing supports of beams on
the adobe walls, and
inappropriate foundation.
Walls are about 35–90cm
thick and weigh about
2
900–1200kg/m .
Roofs are about 20–40cm
thick (excluding timbers) and
2
weigh about 300–600kg/m ;
diameter of timbers is about
5–20cm.
Type 2: Adobe walls with
arched roof
Location: Arid and semiarid
regions especially the deserts
in central Iran, provinces:
Kerman, Yazd, and south of
Khorasan.
Description: Several layers of
mud-straw cover the roof
making it too heavy; collapse
of structure can be prevented if
the supporting walls are
maintained sound.
Walls are about 40–120cm
thick and weigh about
2
900–1500kg/m .
Roofs are about 30–50cm
thick and weigh about
2
450–750kg/m .
