Abstract

In South Korea, floor impact noise in multi-family residential buildings has become a growing concern. Specifically, there is interest in reducing floor impact noise in apartment buildings with a column-beam structure. This research conducted full-scale experiments to examine how floor impact noise is generated in different types of structures and utilized computational analysis to understand the vibration behavior known as ODS of the floor slab during floor impact noise occurrences. The results of the full-scale experiments revealed that the column-beam type apartment units had higher levels of floor impact noise compared to wall-type units. Additionally, through modal testing, it was observed that the column-beam type exhibited a low-frequency mode with significant vibration response within the floor impact noise measurement range. Furthermore, a vibration mode stemming from the internal structure of the beam was present within this measurement range as well. Based on these research findings, it is possible to reduce floor impact noise generation by optimizing beam design. The effective performance of the floor is influenced by the position and characteristics of the beams in column-beam structured buildings.
