RESONANT VIBRATION EFFECTS PRODUCED IN SINGLE-SPAN BRIDGES AND OTHER STRUCTURES BY RAILWAY WORKING

ERREGUNG RESONANZARTIGER SCHWINGUNGEN AN EINFELDRIGEN BRUECKEN ODER AN BAUWERKEN DURCH ABSTANDSWIRKUNGEN AUS DEM EISENBAHNBETRIEB

Fast and heavy loads moving on railway tracks produce vibration and jarring in the immediate surroundings, just as in other dynamic processes such as the out-of-balance forces in rotary machines or the regular impact shocks from building equipment. The heaviest vibrations in railway bridges and line-side structures occur at certain train speeds. The reason for this is usually the coincidence of the structure's natural frequency with the excitation frequency from exactly determinable distance effects, i.e., resonance. Linkage of the vibratory conditions of both frequency modes in relation to certain bridge and vehicle data gives an insight into the relationships between speed-dependent vibration excitation and its effect on bridges and structures near the railway tracks. The annoyance to people in buildings nearby only seldom exceeds what is objectively acceptable in view of the brief duration of such resonance.
