This study intends to explore a teaching philosophy of a Master, a joiner, a cabinet maker, Byeung-Soo Kim who has devoted his entire life on creating and making traditional Korean wood furniture since the elementary school. His teaching method is to make his learners skillful by learning how to make traditional Korean furniture with the traditional technique or joint handmade. They are able to create the furniture in passing through some levels such as a beginning, a middle, a high, and a special class for three years. Each level suggests that the students should study its own joints from laminating, dado, butt, dovetail, mitered, mortise-and-tenon, rabbet, tongue-and-groove and so on. The teaching method is very unique as the technique different and difficult to fine it from other education processes throughout the country.

A one-story, wooden-frame, intermediate-bay model with Dou-Gon designed according to the Building Standards of the Song Dynasty (A.D.960-1279), was tested on a unidirectional shaking table. The main objectives of this experimental study were to investigate the seismic performance of Chinese historic wooden structure under various base input intensities. El Centro wave (N-S), Taft wave and Lanzhou wave were selected as input excitations. 27 seismic geophones were instrumented to measure the real-time displacement, velocity and acceleration respectively. Dynamic characteristics, failure mode and hysteretic energy dissipation performance of the model are analyzed. Test results indicate that the nature period and damping ratio of the model increase with the increasing magnitude of earthquake excitation. The nature period of the model is within 0.5~0.6 s, the damping ratio is 3~4%. The maximum acceleration dynamic magnification factor is less than 1 and decreases as the input seismic power increases. The frictional slippage of Dou-Gon layers (corbel brackets) between beams and plates dissipates a certain amount of seismic energy, and so does the slippage between posts and plinths. The mortise-tenon joint of the timber frame dissipates most of the seismic energy. Therefore, it plays a significant part in shock absorption and isolation.
