Abstract

Masonry arch bridges represent a very significant part of the heritage of road and railway art-works all over the word and especially in the Mediterranean area, both in terms of: numbers; reduced environmental impact; and static efficiency. In these cases, the cost of maintenance is often limited to the content and channeling of surface water and control of vegetation, whichcan eventually take root on the joints of the masonry at the shoulders. In masonry bridges,there are no expansion joints or hinges with support equipment or trolleys, as in metal bridgesand reinforced concrete ones, or paint, or resin surface protection, all items that affect the costof maintenance. The permanent weight of these bridges is very high and, together with themechanical characteristics of the structure, results in very high strength and stiffness againstmoving loads. This is one of the most valuable aspects of masonry arch bridges, making it pos-sible to keep open to traffic safely, without repair actions, bridges that are centuries old andwhich are now subject to vehicular traffic and trains producing actions that are considerablyhigher than those for which they were originally designed.The purpose of this work was a static check on the old Gate Bridge, a road bridge in masonrywhich links Corso Garibaldi and Via Giacomo Puccini in the town of Castellammare del Golfo(Trapani province). An extensive experimental research was carried out for in situ mechanicalcharacterization of the constituent materials and static tests were also carried out to study thestructural response (load–deflection curves) of the arch bridge. Finally, analytical and numeri-cal analyses were carried out for safety verification of the arch stone and for verification of theserviceability condition.
