natural frequencies of the structure, maximum deflections, and extreme accelerations for speeds ranging from 60 to 120 km/h were investigated. The study involved in situ non-destructive testing (NDT). The NDT methods were instrumental in calibrating the models and provided actual values for natural frequencies, displacements, and accelerations. The final step involved the precise measurements of the track geometry using a UPS-80 trolley, which revealed irregularities over the supports where levelling devices were located. The integration of both theoretical and NDT data enabled a comparison with the established safety and structural integrity standards, which led to maintaining the existing speed limit of 60 km/h on the railway bridge in Tczew.
and effective solutions. Many farms lack knowledge in risk management, leading to neglected maintenance and inspections. Common issues include poor ventilation, moisture, and lack of safety standards. The absence of regular inspections of livestock buildings can lead to serious risks such as structural damage and fires. Systematic inspections for early fault detection are crucial. A comprehensive risk management approach - encompassing regular inspections, system upgrades, new technologies, and education - is essential for improving farm building safety.
