The basic stages of development of the program complex for calculation of statics and dynamics of the rod and beam constructions of railway bridges based on combining the finite-element method and the equations of solid dynamics are described.

Some approaches and applications of railway vehicle and bridge interaction are presented. The results of computer simulation are considered.

The article is devoted to the survey and testing of railway bridges by the State Joint-Stock Railway Company «Uzbekiston Temir Yollari» («Uzbekistan Railways»). It is stated that in the existing rules on determination of the capacity of bridges the recomm... see more

The article generalizes the basic criteria of estimating reliability of metal span structures of railway bridges. Recommendations have been offered for increasing reliability and operational safety of the bridges.

The article represents results of inspections of reinforced concrete plates of ballastless bridge surfacing on Byelorussian Railway. Special forms of recording the observable parameters in operational supervision have been proposed. Measures have been sug... see more

The article considers some issues, connected with definition of carrying capacity of abutments of two-track railway bridges.

The existent carrying capacity evaluation method of operational bridge structures (Classification method) was developed in 1930. All the calculations represented there are oriented on hand computation methods and do not take into account some features of ... see more

In the article the results of influence of deformation descriptions of strengthening layer on the tensed-anddeformed state of railway embankment are presented. The comparative FEM analysis has allowed finding out that such type of strengthening has no pos... see more

The structural features of welded railway bridges of the last century were considered. The basic causes of appearance of fatigue cracks in welded joints of railway bridges were assessed. Structural and technological ways of provision of the design life of... see more
