【 摘 要 】

The subject of the paper concerns the problem of vibrations and vibration damping values in steel footbridges with various structural systems (truss, beam and slab, cable-stayed, suspension). In the paper values of vibration damping in steel footbridges determined on the basis of the results of numerous dynamic field tests of the footbridges are presented. The vibration damping values are given as a logarithmic decrement δ. Presented information may constitute a database useful at the stage of designing a new or analyzing existing structures.
