Harmonic Vibration of a Column Structure With Transverse Beams

Introduc t ionStructural vibration and transmission of waves in the vertical direction, from floor to floor.often give rise to low frequency vibration and noise problems in multi-storey buildings of lightweight construction_(Figure 1).This paper discusses harmonic vibration and wave , propagation characteristics at the hum-II lower audio frequencies.up to about ' if 300 1-1:. of a simplified model of a single vertical transmission path of a modular building structure.The model, which has a two-dimensional configuration similar to that of Figure 1a, consists of a tall uniform column loaded at regular intervals (L) with identical transverse beams.These represent in an idealized form parts of multi-mndal floor structures.Pig. 1. Examples of idealized building structures.
