The purpose of this study is to investigate the vertical dynamic response of the wooden floor subjected to various impact forces applied to the mid-span of the floor. Dynamic tests and direct transient response analyses were carried out for the 6.5m-long-span and 1.0m-wide wooden model floor consisted of two 120mm wide and 300mm deep laminated wood timbers and 21mm-thick plywood sub-floor. The results of tests and analyses indicate, i) Dynamic maximum displacements of the wooden model floor subjected to various impact forces obtained using direct transient response analysis by the finite element method agree with those by experiments. ii) The static calculation using the coefficients derived from characteristics of the impact forces predicts dynamic maximum displacements, iii) Dynamic maximum displacements closely relate to both the natural frequency of the wooden model floor and the processing time of the impact force.
