AB  - This paper proposes a methodology for statistical analysis of data obtained by visual inspection of squat defects on the rail head. Rail inspection by visual observation, including measurement of the squat defect position and depth was performed in Pančevo Varoš railway station in 2017. The obtained data about the squat rail defect (defect type 227 according to the UIC 712) on the main tracks was analysed in this paper. The rail defect position was determined regarding the position of the nearest sleeper in the track. Statistical analysis of the occurrence of squat rail defect was conducted according to the performed visual inspection in the field. Statistical data processing was performed for tracks zones according to the vertical stiffness of rail support. Furthermore, the impact of traffic load, the type and the arrangement of sleepers on the appearance of the squat rail defect was considered.

AB  - The paper concerns the issue of infrastructure formation in research and technology development centers. It is established that the key point in the design and construction of such centers is providing the effective functioning of social infrastructure, which is a connecting link for the main structural elements of modern research and technology development centers. The grounds for the necessity of working out a unified pattern for designing research and technology development centers in compliance with the urban planning regulations and research and technology development priorities are given. An integrated model for working out a unified pattern of designing research and technology development centers is suggested. This model envisages creating a harmonized international standard that describes the basic principles of sustainable infrastructure formation in research and technology development centers construction. Based on the research results, the principles of sustainable infrastructure formation in research and technology development centers are set out and worded according to the goals of sustainable development. The authors also give grounds for the applicability of the principles formulated in this paper for the infrastructure assessment of research and technology development centers, both operating and under construction, which will make it possible to target the less-developed elements and draw up the plan of their improvement for further sustainable development. The authors also list emerging technologies to be developed and implemented for the efficient accomplishment of the research objectives.

AB  - This paper analyses the stresses in continuous welded rails on bridges including the aspect of fatigue of rail steel. Furthermore, it examines the possibility to avoid rail expansion joints, while simultaneously exploiting the permissible stress capacity of the rail profile 60E1. Accordingly, general application of permissible values of pressure and tensilestresses prescribed in the current European standards was critically analysed. Paper includes specific application aspects of the prescribed stress values for railway bridges in Serbia. General algorithm for reducing the stresses due to the vehicle/track/bridge interaction, which is presented in this paper, was developed by the authors. This algorithm includes all essential parameters of the bridge structure and railway superstructure, as well as the influence of climate conditions and railway route design.
AB  - Ovaj rad analizira napone u kontiunualno zavarenim šinama na mostovima, uključujući aspekt zamora šinskog čelika. Pored toga, ispituje se mogućnost izostavljanja šinskih dilatacionih sprava, uz istovremeno iskorišćenje kapaciteta dozvoljenih napona za profil šine 60E1. U skladu sa tim, kritički je analizirana opšta primena dozvoljenih vrednosti napona pritiska i zatezanja koje su propisane u važećim evropskim standardima. Rad uključuje aspekte posebne primene propisanih vrednosti napona za železničke mostove u Srbiji. U radu je predstavljen opšti algoritam za smanjenje napona usled interakcije vozilo/kolosek/most, koji je razvijen od strane autora. Ovaj algoritam uključuje sve bitne parametre konstrukcije mosta i gornjeg stroja železničke pruge, kao i uticaj klimatskih uslova i projekta trase pruge.
