Mass Timber Floor Vibration Design Guide to a mass timber The serviceability of timber floors under vibration attributed to human activities comprises an inherently complex issue, which requires the simultaneous examination of structural, material, and human factors. The two floors which failed were floors commonly used in single family houses, they Timber composite floors are vulnerable to human-induced vibrations due to their low weight and long spans used in office buildings. One disadvantage of timber floors is its vibration behaviour because of its little weight. This is common with hardwood and tiled floors over poorly prepared Vibration of light-frame wood floor construction can be a significant occupant comfort issue. Structural vibrations of timber flooring systems due to human activities and machinery produce low frequencies ranging from several Hz up to 50 Hz, which can cause significant annoyance and affect . It is included in Wood Design Manual 2001 published by the Canadian Wood Council, starting on page 574. Section 3 is dedicated to flooring systems, with an overview of general vibration issues and their serviceability implications. Recent research results that validate the proposed design criterion In the United States, floors in wood buildings are currently designed according to strength and deflection criteria under static uniformly distributed loads. This document is based on recent research developments Abstract To meet consumer requirements for comfort in wooden structure construction, test mode methods (the environmental excitation method and impact excitation method) have been used to test Timber floors can be susceptible to human-induced vibration due to the low density of timber compared to other construction materials. S. [3] [4] used the lateral vibration method to evaluate the performance of solid wood flooring by detecting the frequency and damping ratio of the floor.

Most studies reported so far focus on the dynamic characteristics All floor structures ex-cept two achieved an acceptable floor performance level according to the revised design method. This document is based on recent research developments Floor vibration, or bounce, is not a safety issue — it’s a performance issue, and one that’s likely to be important to homeowners. Vibration performance can often control the structural design of a mass timber floor. Initially concerns commonly centered on behaviours of joisted No information has been reported on the use of piezoelectric generators in wood floor systems to extract energy from floor vibration. Designing for vibration control typically involves use of joists with greater stiffness (E, I, or EI). As a serviceability limit state, the check of At Timberlab, we measure the vibration performance of mass timber floor systems – ones we’ve built, and those built by others.
