Abstract

Tsipiani bridge (1875) is located at the East Zagori region in Epirus Greece, near the village of Miliotades. It is a peculiar single-arched bridge, the arch of which appears pointed, with an opening of 26 m. Traditional stone bridges have no wedge-shaped voussoirs, and the final round shape is formed by variable mortar amount amongst the flat sandstones of the area. The current stake is the salvation of the bridge. In the institutional framework of protection, the exact wording of the question is «whether or not» the study is approved. Bridges do not stand by democratic procedures but by the decisive intervention of the engi-neer corresponding to that of the master builder who in this case seems to have carried out a false decentering. In this case our proposal was the method of “stitching” which is used to reinforce existing structures made of stone or brick to increase the resistance of the masonry against compressive, shear and tensile forces and to connect loose parts in the body of the masonry.

Heyman's theory can be summarized as follows: (a) the value of compressive strength is very much related to the level of stress in an arch due to its same weight, so that it can be taken as infinite, (b) even if there is mortar or any bonding material between the arches, the tensile strength is so low that the structure may be considered to be unable to pick up stresses; will not happen.

, Castigliano approach: (a) Tangential movements between lithosomes are not allowed (b) the compressive strength of the interface between lithosomes is infinite (for cases where either the bonding cement is absent or weakened).
