“…Several authors, not only for FRP but also for FRCM and TRM see e.g. [68,69,[70][71][72][73][74][75][76][77][78], utilize interface elements interposed between masonry and FRP reinforcement, but this is quite cumbersome numerically and requires the knowledge of FRP/masonry interface mechanical properties, i.e. a set of parameters difficult to characterize experimentally.…”

“…The critical bending moments used in the structural design were obtained from a plastic analysis of the arch barrel. The analysis was based on the 4-hinge mechanism method first proposed by Heyman [13] for unreinforced arches subjected to a line load representing the axle of a vehicle. In the author's experience, with short span masonry arch bridges it is usually a single axle load which tends to be critical in the design of strengthening measures rather than combinations of two or more axles where there is usually a measure of relief against sway behaviour.…”

Abstract-The rehabilitation of a single span clay brick arch highway bridge is described. The bridge, which dates from 1798, is located in Southern England and spans an inland waterway. Operational constraints and the historic importance of the bridge required the use of a minimum intervention, minimum disruption form of strengthening. Near-surface reinforcement was chosen to meet these requirements. This paper describes the design philosophy and the installation of the longitudinal, transverse and inter-ring dowel reinforcement.

“…The following studies first focused on the arch mechanism and understanding the collapse modes (e.g., Coulomb 1773) and subsequently on analyses based on the theory of elasticity, assuming that masonry could sustain high levels of tensile stress (e.g., Navier 1833; Castigliano 1879). The greatest contribution to the analysis of the arch behavior was made by Heyman (1966Heyman ( , 1969Heyman ( , 1980Heyman ( , 1982 by applying the principles of the theory of plasticity to masonry arches (limit analysis) and introducing the geometrical factor of safety and the safety theorem. Livesley (1978) extended the limit analysis approach of Heyman to include sliding and used linear programming to calculate the collapse load.…”

A great number of masonry arch bridges are still in service in Europe, the Middle East, and other parts of the world. Assessing the capacity of these historical structures is an important problem both for safety and preservation purposes. This paper addresses the assessment of the Titus Tunnel Bridge, a single-span, Roman stone arch pedestrian bridge (Common Era 70) located in Antakya, Turkey, using analytical and numerical techniques. The bridge is located in an active seismic zone and has survived several major earthquakes. Therefore, it is important to understand the Bridge's subtle features that have helped the structure survive for the last two millennia. Furthermore, being a single-span semicircular stone arch, the bridge exemplifies the main construction blocks of several masonry bridges around the world. First, the analytical techniques, i.e., Heyman's geometrical factor of safety and the mechanism method, are used to assess the capacity of the bridge under simple loading conditions and to validate the finite-element (FE) models. Then, discrete FE modeling with explicit time integration is used to investigate the arch behavior under both gravity and earthquake loading conditions. It is observed that the Titus Tunnel Bridge has a significant margin of safety against collapse, which also explains the approximately 2,000-year lifetime of the structure. The results are also used to provide estimates on the maximum expected ground motions in the region using a precarious rocks analogy.
