  • Recently, the wooden structure has been revived again as an eco-friendly structure technique. It is the counterattack of the wood material, which has become more recognized as a finishing material pushed by the concrete material in the rapid growth after the Industrial Revolution. However, it is difficult to conclude that this is a tendency of the construction market in the whole country. Perhaps this is a tendency to appear more strongly in Korea. It could be seen by comparing the characteristics of the overseas construction market with Korean's and the advanced constructed case of large-scale wooden structures in overseas. National wooden buildings show own characteristics such as construction methods, materials, and member dimensions of wood structures by country, which could be seen as a result of continuously developing their own technology. However, in Korea, despite its unique wooden structure and technology (Hanok; Korean traditional housing), it has not been developed continuously and treated it only as a living building exhibit. This is evidenced by the fact that only one percent of the building is constructed with traditional wooden building technology. Therefore, there are various efforts to modernize the traditional wooden structure technology, but it still does not reach the level of advanced wooden technology abroad. The characteristics of the Korean wooden building market were analyzed in order to suggest ways to develop the Korean wood structure technology. The characteristics of Hanok construction were analyzed through quantitative criteria to define the main development tasks for Hanok development to propose the long-term development path.

  • 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.

  • 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.

  • This paper investigates the structural behavior of Korean traditional wooden structures on the basis of the structural analysis using the commercialized program, SAP 2000. All the structural systems were analyzed, and the rotational stiffness at each joint was inferred from the experimental result for a half scale model of Bongjeong-sa (a temple in South Korea). In addition, the artificial control of analysis parameters was prevented because the structural analysis was focused on the realization of the most exact structural behavior of real structures. The analysis was carried out for the horizontal and vertical static loads, and all the secondary members were excluded in the structural analysis. The obtained results show that the resisting capacity of the primary structural system is greater than that of the expanding structural system.

  • This paper presents the digitally implementable methods to preserve and restore the traditional wooden buildings, which are the typical "Korean Cultural Contents," by using computer and multimedia technologies. We first define the meaning of the digital implementation of Korean traditional wooden buildings and important points to be considered. In addition, we present the steps and methods for implementation. Furthermore, we considered wooden materials, structures and Danchung (patterns of paintings on the wooden pieces) in implementing of Gongpo (wooden structure system) for both Geunjeongjeon of Gyeongbok Palace and Injungjeon of Changduk Palace by using the presented methods. We present the mechanical method to digitally implement wooden buildings by using numerical ratios of Gongpo. The other advantage of this paper over the other studies, which focus on implementation of exterior of wooden buildings, is presenting the methods how to show the complicated relations of inner parts in Korea wooden buildings. Thus, it can be practically used in preserving and restoring Korean traditional wooden buildings.

  • The purpose of this study was to estimate the resistance capacity of a traditional wooden house with shear walls made of wood panel. In order to achieve the purpose of the study, the load - displacement test was carried out and the resistance moment values of the shear walls were proposed. The shear walls were made by placing studs with a nominal dimension of $38mm{\times}89mm$ at intervals of 600 mm, and attaching 12 mm thick plywood with 8-d size pegs at intervals of 150 mm. The type of traditional building wall was classified and showed the moment resistance ability of each wall type. This value is expressed as a proportional value divided by the moment resisting capacity of the standard size shear walls not divided into the divided small frames. Although some frames have proportional values larger than 1.0 even though they have openings, most of them show values smaller than 1.0. Also, even without the openings, it showed a smaller value than 1, such as 0.84 and 0.67.

  • This paper proposes an efficient implementation way of traditional wooden building using Parametric modeling method which uses the relations of numerical value ratio between building materials. Building structures and order of construction for Geunjungjeon of Kyuungbok Palace is digitally implemented proving the efficiency of the suggested proposal. Although the existing digital modeling methods for traditional wooden building emphasize the exterior modeling of the building, our modeling method constructed numerous wooden materials and arranged those pieces orderly so that people can see the interior structures of the building which usually is beyond one's vision. The suggested Parametric modeling method, Multi-Object Texture Mapping, Physical Camera Restoration, and GI Renderer for implementing Geunjungjeon of Kyuungbok Palace can be practically used for digital implementation for other traditional wooden buildings.

  • As eco-friendly and sustainable architecture is becoming more popular, the interest in Korean traditional wooden buildings (Hanok) has also been increasing. The building technologies of the wooden construction have been actively developed in all over the world through the diversification of new materials and construction methods. On the other hand, the growth rate of wooden construction market is still slow in Korea. In an attempt to promote the Korean traditional wooden buildings, a comprehensive research project has been conducted. This R&D project is developing standard designs, new materials, and methods for modernized Hanok including houses, public buildings, long-span structures, and even high-rise buildings. To this end, the purpose of this study is to formulate a technological strategy for popularization of modernized Hanok. Influencing variables and issues are analyzed and defined first. At the same time, the five keywords have examined in the perspective of dissemination of modernized Hanok technology. Finally, a technology road map for strategic development of modernized Hanok is proposed through casual diagrams.

  • The density and strength of wood is affected by degradations and defects, such as voids and knots. Old wooden structures such as traditional cultural properties have been deteriorated by these types of defects. They were evaluated by a visual observation that is difficult to evaluate the inner deterioration in structures. In this study, three nondestructive testing techniques were investigated to detect the wooden structural members. Ultrasonic stress wave tests, drilling resistance tests and visual inspections were used to examine the structural wood members. Patterns of Resistograph using by drilling resistance tests could indicate the features of internal wood such as voids, knots, decay, fungi, and so on. The technique just like as ultrasonic stress wave tests, however, difficult to detect exactly area where small amounts of internal deterioration in logs are. In spite of results of ultrasonic stress wave test, the internal deterioration of wooden structural members could be evaluated by the relationship between ultrasonic stress wave tests and drilling resistance tests.

  • Woods have been the familiar constructional materials because they were well suited to natural environments of Korea in terms of history regionalism and nationality. Since the modernization of Korea the wooden structure have mostly disappeared because of constructional costs regulations and convenience. But wooden constructions will reappear because of a prediction of wood demand and supply various choices for life circumstances and various investigations. There are many such cases. Among them Japan became an interesting object of investigation. New wooden constructional structures with new materials and modern skills may be observed in Japan. The purpose of this study is to trace architects' consciousness and to analyze constructions with the combination of wooden and other materials in Japan. Thus we explore a possibility to construct a new wooden structure which is suitable in modern Korea. The results were as follows: First the consciousness of Japanese architects' mixed wooden construction corresponds to the close relations between society and environment. Second the space of a structure with mixed wooden constructions in present Japan is chosen as the best way to consider functions and environments according to the form of need space scale and quality. Third the structure wooden constructional structure is a part of roof open space. in this case woods are represented and composed of japanese traditional wooden structure with new technique. Forth a mixed wooden construction has been used through a merit of each material by mixed of different materials as well as beauty of form.
