My third, 19-year old son just walked into my room looked in the screen at your question and told the rotation immediately.

К искусственным сооружениям предъявляются особые требования в связи со специфическим характером динамических нагрузок, вибрационных и шумовых характеристик при высоких скоростях движения. В последние годы отдаётся предпочтение конструкциям из предварительно напряжённого железобетона. -------------------------------------------------- Note added at 3 hrs (2015-10-09 16:12:14 GMT) -------------------------------------------------- MSZ 4710-4:1970 Fővasúti előrefeszített betonalj.

Typical ballasted railway track and its components are presented in Figure 1 (1). It has been chronically believed based on the industry practice that railway concrete sleepers possess reserved strength that are untapped. Accordingly, it is crucial to evaluate the spectrum and amplitudes of forces applied to the railway track, in order to understand more clearly the behaviors in which track components respond to those forces, and to identify the processes whereby concrete sleepers in particular carry those force actions. Recent findings show that the nature of the majority of loading conditions on track structures is of dynamic impact (2). Those loads are normally of short duration but of very high magnitude. They are ascribed to the wheel/rail interactions associated with irregularities, i.e. wheel burns, wheel flats, corrugations, non-uniform track modulus, and any other out-ofround wheel defects. Structural performance monitoring is an effective way to establish better understanding into the impact behaviors of prestressed concrete sleepers. http://ro.uow.edu.au/cgi/viewcontent.cgi?article=1381&contex... |
