A diaphragm arch is a transverse wall-bearing arch forming a partial wall dividing a vault or a ceiling into compartments[1] while also bracing the walls.[2]
When used under a wooden roof (with solid spandrels) it has the advantage of providing a partial firebreak.[3] It was first used in Roman Syria, during the 2nd century AD.[4] The diaphragm arch is present in Islamic, Carolingian, Ottonian, Romanesque[2] and Gothic architecture (a solution often employed in Catalan Gothic, for instance).[5][6][7][8]
