On the Inclination of a Flying Buttress Arch

Abstract Historically in architecture, the inclination of a flying buttress arch is determined as amplitude angle that spans between horizontal straight line and connecting two ends arch’s lower edge. Nonetheless, this does not represent entire flyer, but at most only its Therefore, using techniques based on geometrical mechanical criteria, applied to twenty flyer arches belonging twelve buttresses from several European Gothic cathedrals, we present new proposal for definition which represents arch.
