Measurement about Walking Vibration on Cross Laminated Timber Floor, and Examination Span Table Result by Finite Element Method

In recent years, in Japan, the structural design system of Cross Laminated Timber (CLT) buildings is being developed, but the habitability of CLT building is still incompletely understood. In this study, we measured vibration characteristics on the CLT floor in the case of walking vibration that generates by humans activities on the floor, and is one of the performance affecting the habitability. Then, based on the results, we analyzed vibration by finite element method (FEM), the presentation of the example of the span table of CLT floor from the viewpoint of walking vibration. First of all, we examined the CLT building floor about eigenvalues, attenuation characteristics, response acceleration by walking vibrations, and evaluation by sensory test. Then, we did vibration analysis by the FEM, and obtained basic knowledge to contribute to the design of the CLT building floor through comparing the examined results with the analysis results. Next, we did FEM analysis with span as a parameter, and present the example of the span table of the CLT floor from the viewpoint of walking vibration.
