Abstract: In order to meet people′s objective requirements for the comfort of wooden structures, for the floor structure of a two-story light-wood residential building with six measurement points, the environmental excitation method and the impact excitation method were used to carry out the dynamic vibration test of the floor structure under environmental excitations of the fundamental frequency and impacts including ball excitations and pedestrian excitations. Frequency, acceleration peak, speed peak and effective value test results were analyzed for comfort. The research shows that the measured fundamental frequency of the building structure under environmental excitation and impact excitation is higher than 4.5Hz, which can meet the comfort requirements; the maximum value of the measured acceleration peak value under the impact excitation mode is 407.2mm/s2, and the human body is between the feelings of uncomfortable and obviously uncomfortable; the maximum value of speed peak value is 5.606m/s, which meets the comfort standard requirements; the maximum value of the acceleration effective value is less than 0.45m/s2, which meets the requirements of building comfort. The result of the comprehensive evaluation is that the floor structure meets the comfort requirements.
