Reliability-based assessment of masonry arch bridges

Assessment, Reliability and Maintenance of Masonry Arch Railway Bridges in Europe

The main purpose of this paper is to give an overview on the state of the art of inspection, assessment and maintenance of masonry arch railway bridges by the presentation of the results of an ongoing international research project run by the International Union of Railways (UIC) with the participation of 14 railway administrations. The survey has shown that the European railways partaking in t...

The Behaviour of Skewed Masonry Arch Bridges

A Parametric Study: Frame Analysis Method for Masonry Arch Bridges

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...

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...

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...
