Most of the cultural assets in Korea are wooden structures. Due to the material characteristics of wood, the preservation of traditional wooden structure is impossible by simple maintenance. Damaged member is replaced with new member or completely dissolve and restore them. But member has a cultural value, so that it is impossible to arbitrarily replace each member. Although the preservation treatment method using synthetic resin is emphasized, there is no exact standard for proper reinforcement ratio. This paper is experimental study for reinforcement ratio of wooden flexural member with synthetic resins, Reinforced ratio on section area of flexural member. As a result, synthetic resin reinforcement are selected as experimental variables by proper ratio enhanced flexural capacity of reinforced wooden member than new wooden member.

"삼국유사(三國遺事)"에 의하면 황룡사 구층목탑은 백제의 장인 아비지(阿非知)에 의해 선덕여왕 13년(645)에 건립된 것으로 전한다. 이후 고려 고종 25년(1238) 몽고군의 침략으로 사찰이 완전히 불타버리기 전까지 약 700년 동안 당시대인의 정신문화 속에서 최고의 자리를 차지하는 상징이자 호국불교의 구심체로서 존재하였다. 그동안 많은 연구자들이 문헌기록과 발굴조사 자료를 근거로 황룡사 창건 목탑에 대한 구조와 전체적인 형태에 대한 다양한 복원안을 제시해왔다. 하지만 그들이 제시한 황룡사 목탑의 모습은 기본적으로 현재 남아 있는 목탑지의 외형적인 형태와 단순한 목구조를 가정한 사각구층의 형태였다. 이는 관련 자료의 부족과 제한된 지식으로 인해 황룡사 창건 목탑의 기술적 계보에 대한 충분한 인식이 부족한 시기에 이루어진 것이어서 새로운 자료의 발견과 고대 대형 불탑의 구조 체계에 대한 인식 정도에 따라 충분히 수정될 수 있을 것으로 생각한다. 본고에서는 2005년부터 진행된 <황룡사 복원 연구>를 통해 정리된 목탑지에 대한 재분석 자료를 근거로 동아시아 고대 불탑의 구조 체계에 대한 폭넓은 이해 속에서 황룡사 창건 목탑의 계보와 구조에 대한 새로운 인식이 필요함을 제안해보고자 한다. 황룡사 창건 목탑은 통일신라와 고려시대에 걸쳐 적어도 두 번의 큰 중창을 겪는 동안 기단의 규모와 평면 형식 등이 변화된 것으로 추정되며, 이에 따라 상부 구조에도 큰 변화가 있었을 것으로 파악된다. 발굴조사 결과 드러난 유구에서 삼국시대에 만들어진 것으로 전하는 구층목탑과 관련된 흔적은 현재 판축으로 조성된 기단토와 심초석 정도이며, 그외 초석과 기단 석재 등 대부분은 9세기 이후의 것일 가능성이 높다. 따라서 황룡사 창건 목탑의 실질적인 구조는 당시 동아시아 대형 불탑의 변화과정 속에서 이해하여야 하며, 기술적 계보는 북조의 영향을 받은 백제의 대형 불탑에서 찾아야 할 것이다. 나아가 남산 탑곡 마애조상군에 표현된 9층 마애탑의 모습과 황룡사지 강당지에서 출토된 금동제 불탑 난간편 분석을 통하여 파악된 고고자료를 근거로 황룡사 창건 목탑의 이미지를 추정해본다면 외형상으로뿐만 아니라 구조적으로도 지금까지 우리가 인식하고 있던 순수한 목구조를 한 사각구층탑과는 다른 형태로 파악되는데, 아마도 실심체를 갖춘 이원 구조의 팔각구층탑일 것으로 파악된다.

There are many Korean traditional wooden structures that have resisted successfully over more than several hundred years. However, their structural behavior is not known in engineering context yet. It is then difficult to predict how they behave against various loadings if they face. This paper is to attempt to investigate structural performance of the wooden structures using fuzzy concepts rather than definitely defined engineering formula. The fuzzy synthetic theory to a scoring method enables us to draw a representative and comprehensive value from individual quantity.

As the corner of wooden pagoda forms the roof by closely bordering left and right eaves on the various purlins and angle rafters, it is designed for every face to be recognized as front whose structure system increases load to bear proportionally. The corner of wooden pagoda is inseparable with the corner bracket set as it becomes stable thanks to the corner bracket set structurally and load burden under restrained structure makes the corner bracket set really important. Accordingly, this study could figure out some facts by analyzing corner bracket sets of Palsangjeon of Beobjusa Temple in Korea, Seokgatap of Bulgungsa Temple in China and Ojungtap of Beobryungsa Temple in Japan which were constructed with pure wooden structure. This study demonstrated that corner bracket set played a pivotal role in keeping balance of concentrated load of corner (corner of opening) in each floor that contributed to the stability of wooden pagoda structurally despite multiple duplications of floors and also figured out the outfit of corner bracket set was subject to the floor type and the cross section of Gongpo installed on top of Pyeongju. Wooden pagodas in 3 countries were two floor types of octagon and square, and employed different connection method between upper and lower floors. The difference between floor and duplication method determines the method of corner, but even different methods were sufficient to have entirety in every side by completing dynamic principle of corner bracket set even though old method had to solve the problem of concentrated load and it also confirms that it was essential Gongpo to prevent any deformation of corner.

The most widely used material in furniture is wood. It is not only because it has good machinability and can be easily accessed, but also it is eco-friendly and human-friendly. Such material has been continuously being used for furniture and its machining method has been being actively researched and developed. Lumber has and has developed its own machining method. The conventional lumber machining method is difficult to make various types of furniture because it focuses on solving lumber's own modification problem due to the swelling and shrinking, and durability. Considering such characteristic of the material, a method to make it light and durable has been being researched and possibilities were found in wooden ships. Wooden ships are ships made of lumber, and are light and strong to be used in water. Also, in order to reduce the water resistance, it has streamlined curves so is formatively beautiful. The elegant curves and light and strong structure showed sufficient possibility to be used in furniture. Thus, the purpose of this study is to find a method to make various shapes of lumber lightly and strongly, using the production method of wooden ships, and to use this production method in designing furniture to propose a new form and structure of bench design, differentiating from conventional monotypic furniture.

In korean traditional wooden structure, to know the critical pass of roof load transmission is very important. to know the critical pass of roof load transmission and to find the role of each dori members, used loading block and load cell. The total weight of loading blocks was 5,8880 N and the number of loading blocks were 16, The experimental fran1e has 1/2 scale. From middle-dori to outside-dori, the linearity of line can't guarantee. So, the distribution of roof load in dori is effected by the initial state of dori. In this research, to remove the effect of initial state, initial deformation was allowed by initial setting.

In the structural analysis of the Korean traditional wooden structure, while the understanding of the transfer mechanism of roof load is very important, there are few researches on this subject. So, some modeling methods considering the connecting methods of the Korean traditional wooden structure are suggested, the results using each modeling method are compared, and the most reasonable analytical model is presented in this study.

There remain several archiectural drawings which was made in Chosun dynasty, which are quite different from current drawings. The site plan which is composed of slanted elevations doesn't exhist in Western drawing method. This elevation development method is common in Korea, China, and Japan. These three nations also have a common point which the wooden structure are popular. So elevation development method is reasonable to represent the wooden structure. Because a drawing mehod reflects cultural character and thought, it is important to read the architectural perception at that time. In this viewpoint, I studied the characters of the drawing method in Chosun dynasty according to the peoriodical articulation of century, and how the drawing method reflects the thought at that time. And I suggested a new posibility of effective and reasonable drawing method for the wooden structure.

Among the various problems involved in the structural analysis of the Korean traditional wooden structure, the analytical model for the Kong-Po is controversial subject as usual. While some experiments are tried for establishing the basis of analytical models, most of these experiments are performed using scale down specimens. So, it is not possible to apply these experimental results to structural analysis of Korean traditional wooden structure directly. A numerical study for analogizing the stiffness of full scale Kong-Po structure is performed on the basis of experimental specimen. Some parameter studies using finite element method are made in this study. The finite element analysis used in this study is geometric material nonlinear analysis. The stiffness of Kong-Po structure found out in this study can be used for modelling the joints of the Korean traditional wood structure in frame analysis.

목조주택은 전통한옥, 현대한옥, 경골목구조, 중목구조 등으로 분류된다. 최근 국내에서 가장많이 건축되고 있는 경골목구조는 외국의 문화이며 전통한옥인 우리문화와 서로 잘 조화롭지 못하여 본 연구에서는 이러한 문제점을 개선하기 위해서 한옥과 현대 목조주택의 디자인 특성에 대해서 분석하고자 한다. 분석한 디자인 특성은 우리나라 한국적 목조 양식과 생활양식에 맞는 미래의 목조 건축의 발전에 크게 기여할 것으로 생각된다. 연구는 공간분석, 평면분석, 구조 시스템 분석, 지붕의 형태 분석, 미학적 분석 등으로 이루어진다. 전통한옥과 현대에 대한 디자인 특성을 분석한 결과로부터 한국형 중목구조 주택의 내외부의 모습과 모듈화요소를 제안하고 평면설계 및 지붕 벽체상세의 개발방향을 제안하였다.
