  • The deterioration of Korean traditional wooden house located in seoul was estimated. This house was attacked by termite. To estimate damage status of buildings, non-destructive methods were applied. Some of the post needed to be replaced due to low strength, estimated by nondestructive methods. The house was installed with boiler heating facility, to use office and public education. This kind of heating system changed the environmental condition of the wooden house. The termite which attacked the house was classified as Reticulitermes speratus. Because of durability of wooden house effected by environment, control of the environmental condition is essential for maintaining the wooden house. The installation of modern facility to traditional wooden house should not change the traditional structure and do not effect to durability of wooden house.

  • This research explores about the construction process and provision of Japanese Wooden Houses. Even though Prefabricated Houses appeared during the 1960's and the Platform Construction System during the 1970's, there was still a high demand for Conventional Wooden House, with a high demand by households on their 30's. These features were found in the areas of Hokkaido, Kyushu, Tokyo, and Osaka. Tokyo and capital region accommodate large number of the head offices of companies that produce Platform Construction System houses, and thus supply the largest amount of Platform Construction System houses. In capital region, land prices are so high, that they build houses as 3-Floors or above, and also driven by high cost of house construction, house performances are excellent. The houses of Osaka and Kinki region demonstrate similar characteristics to those of capital region. Osaka is headquartered by a group of head offices of companies that produce prefabricated houses, and thus holds more amount of prefabricated house supply than other regions. This city also shows high cost of house construction no less than capital region, and thus offers outstanding performance of house. In Kyushu, whereas Japanese wooden house building systems are supplied the most, Platform Construction System houses are provided the least in the nation. As this region offers rich amount of forest resources owing to mild humid climate which is ideal for vegetations, the Japanese wooden building systems use the timbers from this region. Hokkaido, a cold region, requires houses that offer outstanding performance of heat insulation. Therefore, Hokkaido shows more supplies of Platform Construction System houses that offers outstanding heat insulation performance. They import the timbers that form the structure framework of Platform Construction System houses from North America.

  • The aseismic capacity of a traditional three-bay-straw-roof wooden house for rock site condition is quantitatively estimated. One 1/4 scale model was tested for the Nahanni Earthquake with peak ground accelerations from 0.1g to 0.6g. The natural frequency of the wooden house in elastic range is 1.66 Hz and 2.15 Hz in longitudinal and transversal direction, respectively. Damping ratio of the house in elastic range is 7%. The horizontal acceleration response of the house is significantly reduced compared with the input motion due to the nonlinear inelastic characteristics of the Sagae-machum joint of the frame. The traditional wooden house has high aseismic capacity in the rock site condition where high frequency contents of motion are predominant.

  • Historical study of Korean traditional houses have been carried, mainly, based on the geographical region of Korean peninsula. However, the case of primitive houses can not be researched according to the geographical and racial concept of modern nations. This study aims to examine the primitive houses of ethnic minorities of northeastern China, where the cultural and racial background have been deeply rooted in the history of Korea as well as Korean traditional houses. Through the field research and literary materials, the basic types of primitive houses of the five ethnic minorities could be identified. Among these types, those that have possible relationship with Korean houses, are cone shaped house, underground house, and elevated wooden house. Archeological evidences of underground houses were amply found in Korea already, but above ground evidences could not be found. However, It seems quite certain that the cone shaped houses and elevated wooden houses, too, existed in Korea as one of the earliest housing types, as can be examined in remaining examples in Korean peninsula. With no doubt, the primitive houses of Korea have strong connection with that of the ethnic minorities of northeastern China. This can be verified through the facts that the evidences of cone shaped houses, the similarities of the use of Inner space, the evidences of elevated wooden houses. Also, the combination of wooden floor and ondol, which is known to be one of the strongest characteristic of Korean traditional houses, could be originated from the combination of primitive summer house, the elevated wooden house, and the winter house, the underground house with ondol.

  • Traditional architecture has structural limits after some terms because it almost made by wood elements. So in the name of 'Restoration', by anatural process, repair works are accomplished. But the repair works of traditional buildings have some problems in spite of best men power and technology. To overcome this problems, we need more detailed studies for examine the reasons of destruction in elements of wooden buildings. The life limits of wooden buildings are caused by natural circumstances and humanic circumstances, the former has bad effect on the damage in wooden buildings. There are various elements of damage in the wooden buildings, earthquake, the falling of a thunderbolt, fire, and rain, microorganism, insect, and so on. Moreover pollutions-sulfurous acid gas, acidorganic matters -are important reason of shortening the life of wooden buildings. From 1981 till now we investigated important traditional buildings under repair works by the way scientific analysis to catch the sample - seramics, woods, insects, metals, etc. In this reports we suggest various method of investigation with two samples of tradional house made by wood, one is Kim Joo Tea House, the order is Simgum-dang of Magok-Sa(dwelling of monk).

  • Infrared (IR) thermography which is the technique for detecting invisible infrared light emitted by objects due to their surface thermal condition and for producing an image of the light has been applied in various field without damaging the objects. It also could be used indirectly to examine the inside of an object. In this study, insulation property of wooden house in Korea Forest Research Institute (KFRI) was evaluated with according to "Thermal performance of building - Quantitative detection of thermal irregularities in building envelopes - infrared method (KS F 2829)". This method uses "Temperature Difference Ratio (TDR)" between outdoor wall surface and indoor wall surface of wooden building for evaluating its thermal performance. The thermal performance of a room on the 2nd floor of the wooden house was focused in this study and IR thermography on the indoor and outdoor surface of the house was captured by IR camera. Heat loss from the corner and the window of the wooden house as well as wall of the house was quantitatively evaluated and the invisible heat loss in the wall was detected. It is expected that the results from this study could contribute to improve the wooden building energy efficiency.

  • The aseismic capacity of a traditional three-bay-straw-roof wooden house for soft soil site condition is quantitatively estimated. One 1/4 scale model was tested for the Imperial Valley Earthquake up to failure. The natural frequency of the wooden house measured in elastic range is 1.66 Hz and 1.76 Hz in the longitudinal and transversal direction, respectively. Damping ratio of the house measured in elastic range is 7%. The peak horizontal acceleration response of the house was reduced compared with input motion due to the nonlinear inelastic characteristics of the wooden frame. The horizontal displacement response was significantly increased as the level of input motion was increased. The model was collapsed at 0.25g due to the low frequency contents of the input motion. The results of nonlinear seismic analysis were compared with the test results.

  • This research has set up the fire protection and early suppression plan for Asan Oeam folk village which is composed of traditional wooden building instinct or complex. The results of this study are as follows. 1. The traditional wooden buildings require attentive considerations about the fire property of the Waga and the straw roofed house. Especially, as the straw roofed house has property that the transfer and development of the fire is fast. Therefore we studied on the transferring possibilities of the fire dangerous instinct through measuring the distance from of the eaves edge and trees in neighboring house. 2. This research proposes the tools for the priority protective building through consideration of fire risk and cultural priority because the fire prevention for all is impossible at the same time. 3. The most important thing is preserve the cultural identities of traditional folk village in establishing the fire hydrant and fire prevention facilities. Traditional folk village landscape should be considered.
