“…Primjena takvih naprednih probabilističkih postupaka pokazala je da u mnogim slučajevima neki most koji nije zadovoljio uvriježene provjere sigurnosti zapravo može sigurno preuzeti realna uporabna opterećenja, a da nije potrebno njegovo ojačanje ili zamjena [2][3][4]. Učinkovito i ekonomično održavanje, sanacije, rekonstrukcije ili ako je potrebno zamjene konstrukcija mostova može se ostvariti jedino ocjenjivanjem pouzdanosti postojećih mostova, utemeljenom na detaljnim ispitivanjima.…”

“…Therefore, when assessing an existing bridge, the codes developed for new structures are used, which is not satisfactory. Indeed, several bridges were classified as unsafe by applying design codes, while their reliability was found to be high enough, as demonstrated by means of probabilistic evaluation (Lauridsen et al 2007). This shows that a structural assessment using design codes might lead to unnecessary waste of funds with repair and strengthening.…”

When assessing an existing bridge, it is common practice to collect information from the bridge in the form of samples. These samples are in general of small size, raising the question of how the corresponding statistical uncertainty can be taken into account on reliability estimates. The case study illustrates how Bayesian methods are especially suitable to deal with that source of uncertainty. Another strong point of the Bayesian methods is their ability to combine the information contained in the samples collected from the bridge with prior information, if any. This aspect will also be illustrated through the case study.November 29, 2014 1:41 Structure and Infrastructure Engineering jacinto14 Structure and Infrastructure Engineering, Vol. 00, No. 00, Month 200x, 1-

“…Most of the experiences have been done in the field of bridges either from structural concrete (reinforced and prestressed) or steel. Several experiences have shown the large amount of money that can be saved by an efficient and accurate assessment based on a probabilistic approach [7][8][9][10][11][12]. However the application to masonry bridges has been almost negligible.…”

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.
