The objective of this paper is to investigate the response characteristics of Korean traditional wooden structure subject to dynamic earthquake load. To accomplish this research purpose, as a typical example of Korean traditional wooden structures, Bongjeong-sa(temple) constructed in the fifteenth century and classified as a treasure is selected. One-third scale model of Bongjeong-sa is designed and set up on a sliding table of 5.5m by 4.5m to perform shaking table test in the laboratory. To find similarity condition on the natural frequency between real structure and scaled test model, free vibration test was performed for real structure and test model. The natural frequencies of real structure were calculated from acceleration responses measured from ambient vibration test. The test model on shaking table was moved instantaneously toward x-direction of test model structure from 1mm to 10mm for the free vibration test while varying the roof mass in order to adjust similarity condition on the natural frequency. The earthquake signal of Elcentro, Kobe and Hachinohe were used to perform seismic test. The magnitude of earthquake acceleration was controlled as 4 types of 0.07g, 0.11g, 0.167g and 0.22g. The characteristic of instantaneous natural frequency and damping ratio with respect to the magnitude of displacement, velocity and acceleration responses of roof were analyzed.
