Effect of deflection on evaluation of walking vibration of long-span Timber floor from the viewpoint of habitability

Abstract

Walking vibration can cause complaints to building users, especially on timber floor. In previous studies, it is found that there is a difference in the human evaluation for the same vibration between the sensory test result using the shaking table and the sensory test result using the timber full-scale test floor. In this study, the factor of this difference was investigated, and it was revealed that the deflection due to the landing of the foot influences to the evaluation of the lower rigidity timber floor. Finally, adding the deflection effect, the correction method for the previous evaluation method of walking vibration was presented.
