“…The two supports of the vault are made by steel beams: one support is fixed, while the other can be moved by a hydraulic jack, allowing for controlled vertical displacements of one of the abutments of the vault. Two additional steel beams placed on the top lateral shoulders of the vault give further constraints, avoiding rigid rotations of the whole structure [7,8]. The FRCM reinforcement consisted in a basalt fiber mesh (6 mm x 6 mm) embedded in a cement mortar.…”

“…The study of the structural behavior FRCM reinforced masonry construction is even now an open research issue, especially in the case of curved structures like arches, vaults and domes. Indeed, in the literature there are still too little numerical (see, e.g., [3]) and experimental papers [4][5][6][7][8][9] on this subject.…”

“…The experiment, performed on a full-scale vault, required a quite complex experimental setup ad hoc designed [7,8]. In both tests, the masonry vault was continuously monitored through of several sensors placed in appropriate points of the intrados and extrados of the structure.…”

Historical buildings are the cultural heritage of the world. Preservation of historical buildings is important in the past and today. In particular, material fatigue, environmental vibration effects and natural disasters that occur over time cause great damage to historical structures. It is thought that many historical buildings will not reach the next years due to neglect. In order to prevent this situation, historical buildings should be maintained and strengthened if necessary. In addition, historical buildings should have sufficient stiffness to prevent collapse against pre-disaster situations. Stone barrel vaults are one of these historical cultural heritages. Many stone barrel vault type historical structures are frequently encountered today. In order for stone barrel vaults to be transferred to the future, care should be taken and they may need to be strengthened periodically, especially after disasters. For all these reasons, in this study, the foam concrete method, which is one of the retrofitting methods of buildings, is mentioned. Thus, the effect of the foam concrete method applied on an exemplary stone barrel vault on modal parameters has been demonstrated. In this comparative study, it was observed that the stiffness of the stone barrel vault increased with the foam concrete method. As a result of this study, it is suggested to retrofitting the stone barrel vault with the foam concrete method, taking into account the state of the stone barrel vault and environmental factors.

“…One of the possible applications of NDT for historical masonry constructions is the assessment of the effectiveness of past or recent strengthening interventions [3,4]. In particular, a very diffused traditional reinforcing technique is represented by the introduction of tie-rods [5].…”

An experimental investigation on the accuracy of dynamically determined tensile force in tie-rods by applying the interferometric radar technique was performed. Tie-rods were used in historical masonry constructions for absorbing thrusts of arches and vaults, and the radar interferometry may represent a fast and easy non-destructive approach for the tensile force identification in the occasion of structural assessments. Laboratory dynamic tests on a cable under a known tensile force show that, provided that a suitable dynamic identification model is used, tensile force evaluations made stating from interferometric radar measurements were characterized by a very good accuracy (mean error in the tensile force estimation less than 2%), comparable with evaluations made starting from accelerometric measurements. In particular, the dynamic identification model considered is a modified version of a model proposed in the literature. The influence on the accuracy in the determination of the tensile force of some features of the experimental setup, like, e.g., the employ of corner reflectors, is discussed.
