A dynamic computational program considering slip, shear-lag and time-dependent effects of composite box-girder bridge–train coupling system is firstly proposed based on the authors’ previous studies. In program, long-term vertical displacement a bridge calculated. The calculated then superimposed existing uneven track as new excitation to obtain responses system. 3 × 40 m simply supported steel...

BACKGROUND High-speed railway (HR, Electrified railway with service speed above 200 km/h.) noise and conventional railway (CR, Electrified railway with service speed under 200 km/h.) noise are different in both time and frequency domain. There is an urgent need to study the influence of HR noise and consequently, develop appropriate noise evaluation index and limits for the total railway noise ...

With the suspension of investment into V0 railway line, issue lines bypassing Budapest came to front again. As an alternative building a new development existing ones or rebuilding that have been in operation past should be examined. In this paper, we deal with previously operated, now discontinued Danube crossing facility, Solt–Dunaföldvár bridge. Although was minor importance during its opera...

The economy of the steel truss girder bridge superstructure, used extensively in medium and long span ranges, is affected by many factors such as the cost of material, dictated by the configuration and depth of truss, shape and size of members, and cost of fabrication. Most conventional methods of optimization deal with only member optimization assuming only continuous design variables, leading...

The roles of the several parameters that influences railway track deterioration most, are examined in this research with a view to make railway track maintenance more effective and cost efficient. The results presented are based on a comprehensive study of railway track degradation on super structure, sub-structure and geometrical aspects. The changes in TQI (Track Quality Index), the track set...
