In the following work, a Structural Health Monitoring (SHM) procedure combined with adaptive limit analysis is presented with reference to a damaged masonry arch bridge located near Mumbai (India). SHM is performed by monitoring the crack growth under different load conditions. Vibrating wire displacement transducers have been used for this purpose. Then, an adaptive upper bound limit analysis based on a Non-Uniform Rational B-Spline (NURBS) geometrical model, capable of taking into account the existing cracks, has been followed to investigate the residual load-bearing capacity. The obtained results show that the damaged masonry bridge still presents a margin of safety under traffic loads.

Abstract
In the following work, a Structural Health Monitoring (SHM) procedure combined with adaptive limit analysis is presented with reference to a damaged masonry arch bridge located near Mumbai (India). SHM is performed by monitoring the crack growth under different load conditions. Vibrating wire displacement transducers have been used for this purpose. Then, an adaptive upper bound limit analysis based on a Non-Uniform Rational B-Spline (NURBS) geometrical model, capable of taking into account the existing cracks, has been followed to investigate the residual load-bearing capacity. The obtained results show that the damaged masonry bridge still presents a margin of safety under traffic loads.| File | Dimensione | Formato | |
