Connection Fixity Effects On Stress Histories In Riveted Rail Bridges
The riveted type of construction is characteristic of older railway bridges. As some of these bridges approach, or have even exceeded their theoretical fatigue life under increasing train loads, it is desirable to improve the procedures available for the assessment of fatigue-critical details. The aim of this paper is to present results through the use of the FE method, which address the manner...
متن کاملProbabilistic fatigue load spectra for riveted railway bridges
This paper presents a probabilistic load model for fatigue assessment of old metallic railway bridges. The traffic basis of the model consists of trains obtained from past records and present-day trains obtained from codes. The traffic is divided into four distinct time periods each associated with particular characteristics in rail traffic. Traffic evolution scenarios for the future, in terms ...
متن کاملProbabilistic 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...
متن کاملFemtosecond pump-probe microscopy generates virtual cross-sections in historic artwork.
The layering structure of a painting contains a wealth of information about the artist's choice of materials and working methods, but currently, no 3D noninvasive method exists to replace the taking of small paint samples in the study of the stratigraphy. Here, we adapt femtosecond pump-probe imaging, previously shown in tissue, to the case of the color palette in paintings, where chromophores ...
متن کاملAnalyzing the Potential Interface Effectiveness for Cable Barriers in Asymmetrical Median Cross Sections
The primary purpose of longitudinal safety barriers, such as cable barriers, is to contain and/or redirect errant vehicles that depart the roadway, hence keeping them from entering opposing travel lanes or encountering terrain features and roadside objects that may cause severe impacts. In this paper, vehicle dynamics analysis is used to study the effect of asymmetrical median cross-sectional c...
