In this paper, dynamic property of existing wooden house is experimentally evaluated. For this aim, oscillator is equipped on the beam of the single-story wooden house, and enforcing vibration tests are executed. Observed time-domain data are transformed to frequency-domain data, and natural frequencies and corresponding dominant vibrating mode shapes are estimated. To examine structural properties identified by oscillating tests, microtremor measurements are also carried out and relation between natural periods on micro-vibration level and on sensible elastic vibration level is investigated. Through those studies effective allocation of sensors and oscillator is also considered to exactly find out structural dynamic properties. Moreover, under consideration of observed values of the natural frequencies, equivalent 3-dimensional frame model which is composed by simplified elements is introduced and numerical Eigenvalue analyses are executed.
