The subject of research is a steel arch-tied bridge at a high-speed railway line in Poland. After the construction was completed, a resonance phenomenon was observed at the bridge, consisting of the occurrence of intense (visible to the unaided eye) undamped vibrations of some vertical hangers in the horizontal direction, transverse to the track axis.
One of the most common uses of architectural sheet metal is in roofing and cladding. Metal roofs are renowned for their durability and ability to withstand harsh weather conditions. Cladding, on the other hand, provides an extra layer of protection while significantly enhancing the building’s visual appeal.
