Numerical procedure for detecting the optimal stress state within the profile of a cracked arch

Abstract. The method for identifying the line of thrust closest to geometrical axis an undamaged arch, developed by authors in a publication 2019 first time, is extended this paper case cracked arches. Cracks subdivide arch into rigid portions linked in-between correspondence points at extrados or intrados, which can be interpreted as internal hinges. Under assumption, procedure reformulated and cases one two-hinged arch. In paper, presented detail one-hinged
