“…Garrity recognised materials deterioration, spandrel wall detachment, arch barrel defects and foundation disruption as the primary defects in masonry arches [6]. This author's summary is in accordance with other authors who investigated potential sources of failure and collapse of masonry arches [10,[11][12][13][14]. The focus of this paper is longitudinal cracks observed in the case study of the Ivanjica bridge.…”

The importance of masonry arch bridges as a traffic network element calls for a thorough analysis focused on both structural stability and loading capacity of these historical structures, considering the usage of these bridges in contemporary traffic conditions. This paper focuses on the analysis of longitudinal cracks in a single span masonry arch bridge to evaluate its influence on structural behaviour of the system. As longitudinal cracks do not necessarily present an inevitable collapse mechanism, analysis of the causes is crucial for evaluating the serviceability and functionality of the bridge investigated. The methodology is based on the following: literature review, observation of the stone bridge in Ivanjica, geological testing of the site, geophysical testing of the bridge, laboratory testing of mechanical characteristics of stone used for the bridge construction and biological analysis of the samples of implemented materials on the bridge. Finite element analysis of the bridge was conducted to define the causes of the longitudinal cracks. The 3D simulation model was based on the data collected through observation and experimental analysis. This paper provides extensive research on a single span masonry bridge, examining how different deterioration mechanisms, in conjunction, can lead to the appearance of cracks in masonry arch bridges and provide remedial measures accordingly.

“…There is a significant amount of experience in the repair and strengthening of masonry arch bridges in the UK (Ashurst, 1992;Page, 1996;Sowden, 1990) and other countries (AlJolahy and Kulaib, 2006;Wilmers, 2012). This is valuable information when considering similar structures often built by British bridge builders in Australia.…”

Winchelsea masonry arch bridge, Australia: first major maintenance

The existing three-span stone arch bridge across the Barwon River at Winchelsea in Australia was opened on 3December 1867 by HRH the Duke of Edinburgh, Prince Alfred. For 145 years, this now heritage-listed bridge has carried traffic on the Princes Highway West without loading restrictions. An inspection in 2012 revealed significant cracking of the voussoirs and a load rating of 23 t was posted. The Princes Highway West upgrade project will provide a new river crossing so that the stone arch bridge will revert to carrying pedestrians and cyclists. However, during the construction of the new bridge, the existing stone arch bridge is required to be reopened to traffic without a posted load limit to carry one lane of traffic for up to 2 years. An engineering investigation was therefore required to determine what rehabilitation works were required to facilitate this. This paper presents the results of an engineering investigation to determine a reliable way of replacing the cementitious material between the voussoirs of the bridge.The experience obtained during re-grouting of the three stone arches, which was successfully completed in January 2014, is also discussed.

“…Most of the old masonry arch bridges have sustained some form of damage over the years while in service. Some of the common structural problems that they experience, which can lead to failure and collapse, are provided below: (a) deterioration of the masonry material due to thermal effects, moisture, or chemical actions, (b) damage of the arch barrel due to ring-separation, arch barrel distortion and cracking which is a result of longitudinal shear or tensile failure (Ford et al 2003;Melbourne 1991), (c) failure of the foundation which is mainly caused by settlement of supports (Ashurst 1992), and (d) vehicle collision which can interact with abutments, arch barrels or piers (Melbourne et al 2006;Wilmers 2012).…”

Structural Investigation of Masonry Arch Bridges Using Various Nonlinear Finite-Element Models

In the present article, the structural behaviour of a masonry arch bridge in Turkey is investigated. An analytical study has been conducted to provide the geometry of the structure, using laser scanning. A point cloud describing the geometry is obtained and properly transformed into a format, which is appropriate for structural analysis software (CAE). Then, a number of non-linear finite element models is developed, to simulate its structural response. Goal of the article is to highlight the influence of both continuum and discrete approaches and related constitutive laws, on the response of the bridge. Thus, continuum damage laws and a discrete model consisting of unilateral contact-friction interfaces, have been developed. Different load cases are tested and comparison between the results obtained from the different approaches is considered. The failure mechanisms and the ultimate strengths are derived and core points of the used models are highlighted.From the output of this work, it is shown how the different failure models predict the behaviour of the masonry arches. It is also shown that the three-hinge mechanism, which has been depicted in classical studies for single-span arch masonry bridges under a horizontal settlement of supports, may also be obtained for multi-arch bridges. Similarly, downward, vertical settlement of supports may result in the development of two hinges, as in single-span arches. The beneficial influence of the backfill in limiting the failure in the arch, is finally addressed in the article.
