چکیده:
Arches and vaults are of the most important parts of traditional buildings of Iranian architecture. In the traditional architecture of Iran, before oil was discovered, fuel (such as wood) was one of the high-ranking issues. Therefore, Iranian traditional architects did their best to reduce the use of wood. There was however, a revival of the use of brick in construction. Qomi-poosh technology is one of the most impressive and admirable achievements of traditional architecture of Iran, which was invented by Ostad Hassan Qomi. This paper aims to study Qomi-poosh vaults and its execution techniques. Our investigation shows that Qomi-poosh technology could span nearly 6 metres with only 5 cm thickness (the width of a brick), which is equal to one a hundred and twentieth

<H2>REVIEW OF ARCHITECTURAL VAULTS IN IRAN</H2> The variety of different types of Iranian vaults, considering their shape and direct correlation between the geometrical shape and the way the forces are applied to the vaults, causes the need for an independent review.
Comparison of Some Parameters in Different Types of Binding Course Vaults (Roman, Plentiful and Lapoosh) Brick usage in a specific span Vault development direction Load bearing ability Brick arrangement Vault weight per area unit Roman Vault The highest level of brick usage for covering a specific span This vault is built only perpendicular to the seam.
<H2>THE PERFORMANCE &amp; DEVELOPMENT OF THE LAPOOSH VAULT METHOD</H2> What the master builder does in the construction of a Lapoosh divider wall vault is presented in this section.
All point to the insight and knowledge of the builder about how the forces apply and their effects, especially for setting up a Lapoosh divider wall vault (Mahdavinejad &amp; Tehran, 1996).
He made use of the physical property of iron, namely high-tensile property, to develop the span and increase the load bearing of the Lapoosh vault, which later became known as Qomi-Poosh.
This pre-stress post-tension property has used in contemporary technological architecture, to cover extensive spans in concrete constructions.
