An experiment is performed for a two-story wooden frame of real size by a sharking table test. A seismic excitation standardized using JMA Kobe with 90cm/s as the peak ground velocity is applied. The load displacement relations of the tested house is figured out under an assumption that the accelerations multiplied by the corresponding masses give the total restoring forces and these forces cause the relative story displacements that were measured directly for each story during the experiment. In addition, the load-displacement relationships based on static experiments performed for each wall element are evaluated and modeled including finishing walls.The load-displacement relationships are classified into two types of hysteretic rules. One is a bi-linear rule, and the other is a slip type. Based on the comparison of the hysteretic rules between the static test and the shaking table test, the contribution from the finishing walls is analyzed to be 2.0 to 2.5 times the sum of each structural walls obtained by the static experiments.Furthermore, the value of damping factors is evaluated as 5% for the stiffness based on comparison between the shaking table test and the earthquake response simulation.
