“…In the macro-modelling, the masonry accepts as a composite without making a distinction between unit and mortar. Because of its low computational effort, macro-modelling technique is the most common technique for analysis of large scale models and commonly used in the literature [12][13][14][15]. These modeling strategies are given in Fig.…”

Historical masonry arch bridges which are important components of the transportation in many places worldwide are invaluable part of architectural and cultural heritage. These bridges, which date back to hundreds of years, have frequently been damaged or ruined because of unexpected events such as earthquakes. In this study, earthquake behaviour of a historical masonry arch bridge which called Dutpınar is analysed using 2003 Bingöl earthquake acceleration records. The bridge is modelled with three dimensional finite element software. Dynamic response of the bridge is investigated. For this purpose, displacement of the nodal point located at the top of the bridge is achieved. Also, maximum and minimum principal stress and strains are obtained and potential locations of initial damages are evaluated.

“…It should also be noted that, especially in railway masonry bridges, the repetitive design has generally produced good-quality masonry in terms of both mechanical properties and type of block-laying. For this reason, the range of mechanical properties is quite narrow, and does not significantly affect the ultimate behaviour (Zampieri, 2014;Zampieri et al, 2015).…”

In this work, the seismic capacity of single and multi-span masonry arch bridges was assessed by limit analysis. A preliminary statistical survey was carried out on a stock of about 750 railway bridges in Italy, classified according to characteristics and expected collapse mechanisms under seismic excitation. A comprehensive parametric study was carried out on identified homogeneous classes, to calculate limit horizontal accelerations triggering the collapse mechanism in longitudinal and transverse directions. Iso-acceleration envelope curves, representing limit horizontal acceleration\ud of the bridge as a function of geometric parameters, were then derived. These graphs can be used for preliminary seismic safety checking of existing masonry bridges, once the main geometric parameters are available by simple visual inspections and geometric surveys, and can easily be implemented in a Bridge Management System to prioritise seismic retrofitting interventions

“…They reported that arch thickness and spandrel wall height are significantly effective on the overall strength of the structure. It is reported by some of the researchers that, out-of-plane forces are effective on determination of seismic behaviors of arch bridges with long archspan and high spandrel walls [1,10,19] Pulatsu et al [20] examined the damage situations of masonry arch bridges [1] under diverse loads by comparing in-and-out-of-plane behaviors. It was further emphasized that the damages likely to occur on spandrel walls induced by out-of-plane loads affect the load bearing capacity of the structure.…”

Historical masonry bridges generally consist of arches, spandrels walls, backfills, piers and foundations. Under the effects such as earthquake, flood and wind, the most vulnerable structural elements of bridges against out-of-plane seismic motions are spandrel walls. Increasing length and height of spandrel walls increases the vulnerability of the bridge under loads in vertical and transverse directions. The aim of this research is to examine the in-plane and out-of-plane non-linear structural responses of the spandrel walls of a historical masonry bridge. For this purpose, a historical masonry arch bridge with built in 1787 in Bartın-Turkey was chosen as the subject structure. The 3D finite element model and nonlinear seismic analyses of the bridge were performed with ABAQUS. Initially, the backfill-spandrels and backfill-arch interfaces of the bridge were modeled with and without cohesive contact. The non-linear material responses of the spandrel walls and the arch units were defined using Concrete Damage Plasticity material model and those of the backfill unit were defined with Mohr-Coulomb material model. The east-west component of 17 August 1999 Kocaeli Earthquake’s acceleration records was used in the analyses. The east-west acceleration component was applied on the bridge in-plane and out-of-plane directions during the time-history non-linear seismic analysis of the bridge. The results obtained from the analyses with and without the consideration of cohesive contact were compared to evaluate the seismic responses of the spandrel walls. As a result, cohesive interface behavior was found to significantly affect the spandrel wall response under in- plane and out-of-plane seismic forces.
