Abstract: Masonry stone arch, and other types of masonry structures, owed their durability through the centuries primarily to the inventiveness of the builders, who, by introducing new connection elements, managed to build structures that would resist various effects through the time. Connection elements used for assembling bridge vaults, or clamps and dowels made of wrought iron with the additional use of liquid lead and mortar, are one of the successful ways to increase stability and load-bearing capacity of this type of structures. A similar assembly technique was applied during construction of the original Old Bridge in Mostar in 1566 and its reconstruction in 2004. This paper presents experimental tests performed on 1:3 scaled arch segments of the Old Bridge in Mostar and obtained results. This experimental research was conducted in order to describe the behaviour of all connection elements participating in the transfer of loads that can occur. Obtained results of the performed experimental tests are highly utilisable for further numerical analyses and verification of the existing and new mathematical models.
Keywords: masonry arch; connection elements; quasi-static laboratory tests; failure mechanism; loosening of connection.
