INFLUENCE OF EDGE FIXING FOR IMPEDANCE CHARACTERISTICS IN WOODEN FLOOR STRUCTURE

Abstract

We used a full-scale model floor to investigate the impact of edge fixing on the impedance characteristics of wooden floor structures. Our investigation yielded three key conclusions: 1) Joists in wooden floor structures essentially function as simply-supported beams held at both ends. 2) When the wooden joists have standard cross-sectional dimensions, edge fixing increases the driving-point impedance in impact time since the driving-point is very close to the end of the joist. 3) The use of adhesive in addition to screws on structural members in the floor delivers no significant benefit in terms of the impact of edge fixing.
