Abstract

In this work, details of field measurements undertaken at a brick masonry arch bridge under design train traffic and analytical work based on non-linear fracture mechanics are presented. A parametric study is done to study the effects of tensile strength on the progress of cracking in the arch. Further, a stability analysis to assess collapse of the arch due to lateral movement at the springing, in particular near the partially filled land arches is done. The margin of safety with respect to cracking and stability failure is computed. Conclusions are drawn on the overall safety of the bridge.
