An Accurate Life Estimation Method for Existing Railway Bridges

Simplified probabilistic non-linear assessment of existing railway bridges

Probabilistic fatigue life estimates for riveted railway bridges

A large percentage of the railway bridges in the UK rail network and around Europe are of riveted construction exceeding in many cases 100 years of age. The remaining fatigue life of these bridges is difficult to estimate due to the uncertainties regarding the fatigue behaviour of wrought-iron and older steel material, which was used for their construction, as well as the actual loading and the...

Extending the Service Life of Timber Railway Bridges

Times of downturn in economy, tough competition, high costs, and large amounts of capital required for replacements have created growing need for cost cutting measures and for seeking better return on investment. This has also placed an increasing emphasis on maintenance practices to extend the service life of existing railroad bridges. This paper outlines the various factors which playa role i...

Semi-active damping systems for railway bridges

In this paper, a semi-active control system for vibration mitigation of railway bridges is presented. The real time frequency response is estimated using a short-time Fourier transform, employing curve fitting to relevant peaks for increased accuracy. A control algorithm developed in MATLAB® is linked to a commercial FE-software, facilitating application on arbitrary structures. A numerical stu...

Intelligent Software for Railway Bridges Design

The Computer aided design software have not been used as extensively by the profession as the computer aided analysis software due to the inability of these software to capture the complex process of design, which is an open ended problem. Whereas human designers, using their intelligence, domain knowledge, experience, common sense and ability to continuously learn, have been able to solve such...
