This study examines the joint and splice of wooden structure at Geunjeongjeon Hall of Gyengbok Palace, which was constructed in the late Joseon Dynasty. The scope of the study is on the part of columns, the bracket sets, and the frame structure. This research also deals with the relationship between vortical load and horizontal load. Firstly, the examination of the joint and splice methods between the pillar and penetrating ties is on the joint and splice methods of the outer and corner. Through the investigation, it is verified that the joint methods between pillar and penetrating tie on the outer and corner pillars is the method of Sagal joints(cross joints, 사개맞춤). Joints used between pillar and penetrating tie are dovetailed tenon joints, between columns and Anchogong(안초공), between columns and Choikgong(초익공) are tenon joint(장부맞춤). Secondly, the examination of the joint and splice methods of the bracket set is on that of Salmi and Cheomcha(첨차), and Salmi and Janghyeo(장혀). Joints used between Salmi and Cheomcha, Salmi and Janghyeo are halved joint, and between each Janghyeo are stepped dovetailed splice. It is Cheomcha that is used the Jujang-Cheomcha(주장첨차) on center line. Therefore it is connected with each bracket set, which gets to is the strong system, easy and convenient on the construction of that. Thirdly, the frame structure of wooden architecture in royal palace is consist of purlins and beams, Janghyeo(장혀, timber under purlin), tall columns, king posts, etc. Through the investigation, it is verified that the joint and splice methods between purlins and beams are used with the methods of Sungeoteok joint(숭어턱맞춤). It is verified that the joint and splice methods between beams and high columns are used with methods of mortise and tenon joint(장부맞춤), is highly related with tensile force. To reduce the separation of parts, sangi(산지) and tishoi(띠쇠) are used as a counterproposal, which were generally used for architecture in royal Palaces in the late Joseon Dynasty and continued to be used until these days common wooden architecture.

The Wooden Stupa of Hwangnyongsa Temple, existed from Shilla to Koryo Dynasty, is recognized as a typical model of the Korean wooden stupa. The related records on this stupa are found in some historical documents including The Chronicles of the Three States ${\ulcorner}$三國史記${\lrcorner}$. This study, through the interpretation of these documents, attempts to discuss and analyse design and structural methods of the stupa, viz., i) the relationship with both Chinese and Japanese wooden stupa, ii) the height, iii) each floor's linking methods, iv) the 'Noban' (Basement of the upper part), v) structure of the 'Simju' (Central pillar) and vi) the stairs and the handrails. The results of this study would be hopefully used for the further researches as well as the restoration of this precious architectural asset.

Laminated lumber is an engineered wood products using stress rated, seasoned and selected lumber. Each piece of lumber is graded, and then end jointed to produce the required length. This study was carried out to investigate the possibility of wooden artifacts with laminated lumber. It is expected through this research that wooden artifacts, which have originality and local character, can be developed by making design of wooden artifacts through the use of plentiful resources around the local area. A development of new design products, an improvement of distributive structure and the achievement of international competitiveness will contribute to develop the industrial artifacts art in Korea. And, it is necessary to develop a corporation system between industrial craft companies and universities.

This study deals with the method of constructing and repairing column, important element of traditional wooden building. Column should have long-lasting strength and resistance to decay and vermin because it is more important in role of structure than in that of ornament. And the rotten or the split part of wooden column should be repaired regularly or irregularly. First of all, this study treats of general character related to the life length and strength of wood. Then it describes the technical method of choosing proper wood for column and that of carpentering, painting, and mending wooden column.

Modern wooden structures usually are connected with steel fastener type connectors. And joints using multiple connectors in wooden structures will form semi-rigid connection. If connection in wooden structure would be designed to be pinned joint, the underestimate for loads transmitted through connection, would result in the deficient capacity of resistance in connection. And if joints in wooden structures would be assumed to be fully-rigid joint, amount of fasteners needed at the connection could be excessively increased. It will give a bad effect in the view of beauty, constructability and economy. Estimate for the reasonable stiffness of connection might be essential in design of reasonable connection in wooden structure. This paper will suggest analysis modelling technique that can represent approximate stiffness of connections using a common analysis program for double shear connection in order to give help in performing easily the design of wooden structure. It is verified that the suggested approximate analysis modelling technique could represent the behavior in connection by comparing the analysis results with test results for tensile, bending moment.

The Nongso tomb of Sunchang was built in a relatively deep place; hence there was little damage from grave robbers. The tomb was completely filled with a large amount of charcoal, and therefore the wooden coffin was excavated in relatively good condition. On the basis of the structure of the tombs, excavated artifacts, and radiocarbon dating results, the tomb is estimated to be from between the late Goryeo and the early Joseon period. The wooden coffin excavated is double-layered structures consisting of an outer coffin and an inner coffin. The outside of the wooden coffin is thickly lacquered and decorated with yellow letters and white motifs. An analysis of the pigments' components revealed that the major component of the letters was gold (Au) and the major component of the motifs was silver (Ag). The coffin lacquer had three layers: a pigment layer, a yellowish-brown layer, and a black layer. The wooden bases of the coffins were painted with a black substance, such as soot, as mineral elements were not detected in the black layer. The yellowish-brown layer is presumed to be refined lacquer. From the analysis of the structure of the layers and pigments, we can estimate the method was adopted for making lacquer for wooden coffin. It is assumed that the method used gold leaf and gold powder. The form of the pigment and the internal structure are likely to be gold leaf, but the shape of the surface letters appears to have been formed using gold powder. This study will serve as important information for understanding lacquer making techniques at the time of the tombs' construction by confirming the making method through reproduction experiments using gold leaf and gold powder.

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 thesis mainly deals with how 'count of Ryang' was used in the Daehan Empire. Count of Ryang means how many purlins were used in the building with longitudinal section. As a result, the notion of Ryang in the Daehan Empire does not differ from now one. But the usages of that are different from the Joseon Dynasty, and from the present. In the Daehan Empire, count of Ryang mainly was appeared with another word, count of Kan. In the Joseon Dynasty, they used the count of Ryang combined with Kan. Count of Kan had the meaning of purlin-directional length. By doing that, count of Ryang indicates the size of flank, count of Kan indicates the length of front. But in the Daehan Empire, count of Kan, especially the beam-directional length was considered at first, and then count of Ryang. Separately they used another count of Kan meaning the area of building. By using the combined words, count of Kan and Ryang in the beam direction, they got focused on the frame of wooden structure than before.
