| | Summary: |
| | Equilibrium analyses of masonry arches usually consider their convex forms,
such as circular, elliptical or pointed. However, besides them, there are also different
concave or inflectional arches’ shapes. Therefore, the aim of this paper is to apply the
thrust line theory to a basic arch of the concave form – a draped arch, which consists of
two annular sectors leaning against each other, oriented oppositely in comparison to the
semicircular arch. In accordance with the applied normal stereotomy, which implies
generic sections perpendicular to arch’s axis, the problem of equilibrium under selfweight is analytically treated, and the closed-form expression for the thrust line is
determined. Moreover, limit equilibrium state is considered, and the analytical solution
for the minimum theoretical thickness of draped arch is provided. |
