Implications of Arch Warp Altitudes on an Ancient Masonry Bridge under Ground Movements

Finite Element Modelling Tuned on Experimental Testing for the Structural Health Assessment of an Ancient Masonry Arch Bridge

This paper presents the structural health assessment of a railway ancient masonry arch bridge located in Bologna, Italy. A three-dimensional finite element model of the entire bridge, tuned on in situ experimental tests, has been used for the assessment. In particular, the finite element model has been employed to evaluate the structural health of the bridge both in its actual state and in the ...

Deflection Measurement of Masonry Arch Bridges with Tall Piers: Case Study of Shahbazan Bridge

A common practice for detailed assessment of masonry bridges is to use recorded deflection signature of mid-span of such structures due to predefined loading schemes. However, measuring the deflection of bridges with tall piers or those situated over deep valleys introduces certain difficulties, since common deflection-meters require a reference point relative to which the measureme...

Warp Bridge Sampling

Bridge sampling, a general formulation of the acceptance ratio method in physics for computing free-energy difference, is an effective Monte Carlo method for computing normalizingconstantsof probabilitymodels.The methodwas originallyproposedfor cases where the probabilitymodels have overlappingsupport. Voter proposed the idea of shifting physical systems before applying the acceptance ratio met...

The Behaviour of Skewed Masonry Arch Bridges

Sensitivity Analysis and Parameter Identification on historical Masonry Arch Bridges

Close to reality computation of the serviceability and load-carrying capacity of old masonry arch bridges for rising live loads is a current problem. In Germany many of such roadand railway bridges exist. Some of the most important features for applicable numerical evaluation of masonry arch bridges are a realistic structural model (very often three dimensional models are necessary), the consid...
