“…In spite of these doubts, a few authors took the challenge and applied continuous beam theories for masonry arches. The papers of Audenaert, Peremans and De Wilde (2004) and Audenaert, Peremans and Reniers (2007) are excellent examples for this approach: the authors developed a linearly elastic, perfectly plastic, no-tension model in the frame of a classical beam bending approach.…”

Abstract:The magnitude of horizontal reactions under self-weight are analysed for pointed barrel vaults with different eccentricities. The magnitude is expressed as the function of the eccentricity (deviation of the pointed generator curve from the circle). Vaults with fixed supports and with increasing outwards support displacements are considered. An analytical model based on continuous Timoshenko beam theory is suggested for barrel vaults and then checked with computer-simulated experiments. The results show that with increasing support separation, the horizontal reaction tends to be at a constant value when reaching the statically determinate state. After this, the horizontal reaction varies only because of the gradual modification of the geometry due to large support displacements.

“…According to UIC 778-3 (second edition), the MEXE method is to be employed for assessment of masonry arch bridges at ultimate limit state, since the 4-hinge mechanism is the most probable mode of failure in single-ring arches [25]. On the other hand, BD91-04 proposes the following equation for assessing ULC of masonry arch bridges, in which "p" is the compressive force in the arch ring due to ultimate design load effects, "b" is the width of the arch ring under consideration, and the rest of the parameters are as defined before.…”

Assessing safety of a railway stone arch bridge by experimental and numerical analyses Bridge response to predefined loading schemes is described and recorded by instrumenting the structure with deflectometers and accelerometers. Test results suggest that although vertical deflections of mid-spans are almost constant for all crossing speeds, the root mean square of acceleration values are positively correlated with the crossing speed. Field test results are then used to calibrate and verify the 3D finite element model of the bridge, and the latter is employed to assess behaviour of the structure at the serviceability limit state. Ocjena sigurnosti kamenog lučnog željezničkog mosta eksperimentalnim i numeričkim analizama U radu je opisan odziv mosta na unaprijed definirana opterećenja, a određen je pomoću deflektometara i akcelerometara koji su u tu svrhu postavljeni na konstrukciju. Rezultati ispitivanja pokazuju da su vrijednosti korijena srednje kvadratne akceleracije pozitivno usklađene s brzinom prolaska, iako su vertikalni progibi na sredini raspona uglavnom konstantni pri svim brzinama prolaska. Rezultati dobiveni mjerenjima na terenu korišteni su za verifikaciju prostornog modela mosta, koji je korišten za ocjenu ponašanja konstrukcije pri graničnom stanju uporabivosti. Bewertung der Sicherheit der gemauerten Eisenbahn-Bogenbrücke durch experimentelle und numerische AnalysenIn der Arbeit wird die Reaktion der Brücke auf vordefinierte Belastungen beschrieben. Diese Reaktion wurde anhand von Deflektometern und Beschleunigungssensoren gemessen. Die Untersuchungsergebnisse zeigen, dass die Werte der Wurzel der mittleren quadratischen Beschleunigung mit der Durchgangsschnelligkeit positiv übereinstimmen, obwohl die vertikalen Verschiebungen in der Mitte der Breitspanne bei allen Durchgangsgeschwindigkeiten vorwiegend konstant sind. Die Messergebnisse vor Ort wurden für die Verifizierung eines Brückenraummodells verwendet, das für die Beurteilung des Verhaltens der Konstruktion beim Grenzzustand der Gebrauchstauglichkeit eingesetzt wurde.

“…In the case of an unique ring, either made of a single masonry or of several interrelated units of masonry ( see figure 1), the most likely failure mode is due to the formation of a four-hinge mechanism because of an extreme load [22]. The mechanism normally appears before any separation between units or crushing of the material occurs.…”

The paper presents a methodology for the probabilistic assessment of masonry arches at the serviceability and ultimate limit states. First, it explains the definition of the different failure modes and corresponding limit state functions that may occur depending on the type of masonry construction (single-ring and multi-ring). The most reported modes of failure are the four-hinge mechanism, the ring separation in multiring arches and the slippage at the foundations. Because of the lack of reliable material data (in the statistic sense) or available response models, only those more prone to be analyzed using reliability-based methods are shown in this paper: four-hinge mechanism and ring separation.The possibility of fatigue failure of masonry arch bridges under service loads and the proposal of reliability-based assessment methods at the ultimate level of the 4 hingemechanism are also analyzed. Finally, the proposed methodology is applied to an existing bridge.
