This study aims to examine the cutting traces remaining on the bracket tie beams of Sungnyemun gate, identifying the tools employed during the late Goryeo to early Joseon periods by specific processes, and deliberating on the timber shaping techniques utilized in advanced architectural construction during the late Goryeo to early Joseon eras. Through the research, it was confirmed that in the production of Sungnyemun Gate's bracket tie beams during the 14th to 15th centuries, both the timber splitting and ripsawing methods were used in conjunction. Moreover, the wood finishing process revealed the use of a plane. It can be inferred that the characteristics of the plane used during that time were not significantly different from those observed in the later period of the Joseon dynasty. The ripsawing and plane finishing techniques were evident in various parts of the bracket tie beams of Sungnyemun gate across the reigns of king Taejo and Sejong, indicating that the techniques involving ripsaw and plane were already prevalent in the late Goryeo period. Consequently, it can be inferred that the ripsawing and plane finishing techniques might have been applied in the construction of prominent government buildings in Hanyang(Seoul), including Gyeongbokgung Palace, and in the residences of royalty and nobility after the establishment of the Joseon dynasty.

본 논문에서는 이 시기의 일본의 건축기법에 대해 일반적인 인식을 소개함과 동시에 필자가 연구하고 있는 의장기법을 일부 소개하고자 한다.

연층을 가지는 건축물들의 피해사례가 관측됨에 따라 기존 건축물 내진성능평가시 수직비정형의 고려가 중요해졌다. 하지만 기존 방법은 수직비정형을 충분히 반영하기 어렵기 때문에 수직비정형을 가지는 건축물에 대해 내진성능을 과소 혹은 과대평가할 여지가 있다. 본 연구는 강성기반 연층비(Soft Story Ratio, SSR)를 이용해 수직비정형 건축물의 내진성능평가 기법을 개발하는데 목적이 있다. SSR은 변위에 대한 요구량과 능력의 비율을 나타내고, 강성차이에 의한 수직비정형을 고려하여 건축물의 변위집중 비율을 의미하는 파라미터다. 1층 기둥을 변수로 하는 필로티 건축물 네 개를 대상으로 개발한 내진성능평가 기법을 기존의 내진성능평가 기법과 비교하였다. 기존 기법은 수직비정형이 극대화되는 모델에 대해 내진성능을 과대평가하는 경우가 발생하였다. 반면 제안된 기법은 모든 모델에 대해서 상세평가의 결과와 동일했다. 따라서 제안하는 내진성능평가 기법은 수직비정형이 극대화되는 필로티 건축물에서 기존의 방법보다 정밀하게 내진성능평가 결과를 제공할 수 있다고 사료된다.

The domestic of modern architectural remodeling method emphasizes simple aesthetic elements, and the correct design and construction methods are not established based on quantitative grounds, thus damaging the value of cultural properties. This study attempts to re-examine the value of modern buildings recognized as old buildings. It is a basic step to present the correct remodeling of the building. The design criteria for exterior wall remodeling of modern buildings were presented. These research results are suitable for energy conservation design standards and can prevent defects in buildings. In the future, more accurate analysis will be required by securing physical property values for various domestic materials through subsequent research.

The grade of East Asian architecture is generally classified by the size, the shape of the roof, and the type of bracket set. The craftsmanship of columns, beam, purlin, stylobate, column base stone and paintwork is also a contributing factor for such classifications. These classifications can be found not only in historical documents such as Oksajo(屋舍條) of Samguksagi(三國史記) but also in house details regulations of residential architecture(家舍規制) of Joseon Dynasty. However, there are differences in detailed designs among the same grade of architecture regardless of the classification. In this research, the Palace, the Royal Residence(宮家), and the Jaesil(齋室) are considered as the Palatial Buildings and Royal Residences. And the advanced architectural ㅇ details which appear only in the Royal Architectures are defined as the ‘The Architectural Crafts as a Code of Manners’. The Architectural Crafts as a Code of Manners is detailed design, which can be seen as fabrication of materials and supplementary factors. The Architectural Crafts as a Code of Manners used in the Palatial Buildings and Royal Residences reveal the types and their historical changes. This research will present a basis for the repair and restoration of cultural heritages to be carried out in the future, and also prevent them from further damages, thus help to preserve the cultural heritages.

The traditional earth wall structure consists of a Joongkit(a small reinforcing post inside a wall) and a Oe(a miscellaneous tree, rendered laths) based on the space between the columns and applying the soil. The members who act as the base layer before applying soil used joongkit, sakmok, and oemok, which are known to correspond to the current joongkit, gasisae, and lath strips. This study was designed to understand the following through an analysis of the ancient texts, such as uigwe. Through a study on the usage and specifications of joongkit recorded on the uigwe, I wanted to reveal that joongkit is a material that has different specifications, functions, and installation techniques from current joongkit. The purpose of this study was to present the differences and technical features of the components of use for two types of oeyeokki technique of traditional wall. In addition, the items to be considered at the actual cultural heritage repair site were reviewed in the restoration of the earth wall weaving technique.

우리나라에서는 1995년 부터 시설물의 안전관리에 관한 특별법(이하 시특법)이 시행되어 왔다. 그 이후, 우리나라에서는 크고 작은 사건사고가 있었고, 구조적 안전성 확보를 위해 수차례의 법 개정이 있었다. 한국시설안전공단에서는 건축물 정밀안전점검 및 정밀안전진단 보고서를 시특법에 근거해 평가하며 그 결과를 사례집을 통해 주기적으로 발간하고 있다. 본 연구의 목적은 안전성 검사 및 진단을 위한 기술 및 제도 개선 방안 도출에 있다. 이를 위해 2011 년부터 2015 년까지 시설안전공단에서 발행한 정밀안전점검 및 정밀안전진단 보고서의 평가 사례 데이터를 비교 분석하였다. 비교 분석 결과를 토대로 정밀안전점검 및 정밀안전진단 수행 중 발생하는 문제의 원인을 파악하기 위해 전문가를 대상으로 한 설문 조사를 실시하였다.

Since then undergoing safety accidents great and small, legal system was revised several times for safety promotion. As part of its efforts Korea Infrastructure Safety & Technology Corporation have periodically evaluated the building safety inspection or diagnosis reports based on Special Act for Safety Control of Public Structures and published annual casebook. This study investigates and examines the cases of bad or poor reports until now. This paper aims at reasoning out the technical and institutional improvement plan for error-prone problems when safety inspection of buildings.

The color that painted on the ground of Dancheong becomes Gachil(basecoat)-Dancheong and underpainting of Moro-Dancheong or Geum-Dancheong. So, the color of underpainting is the most important element that determines impression of the building. Thus, the architecture after using “Sangrokhadan” has different characters from what it had been. In the existing perception toward the background color of Dancheong, it was considered the characters of Korean Dancheong so-called “Sangrokhadan” that paint vertical elements like columns red and upper part of the columns green. But this study examined the color of Dancheong according to the era and region before and after Goryeo Dynasty era, then it reveals that Sangrokhadan technique was applied from the 14th century in the late Goryeo Dynasty. One of the Goryeo architecture, Geungnakjeon Hall of Bongjeongsa Temple is thought to be a previous style that is not applied “Sangrokhadan” technique because old elements are painted red pigment.

The bracket sets which are supporting the weight of the roof, has to meet both requirements which are structural functions and act as an ornamental element. Therefore the bracket sets differ in many types from time and space and has done an important role in the history of architecture with many studies being presented. The first form of the bracket set has been found in the bronze table relics in zhōng shān wáng líng (中山王陵). Through the Eastern Han dynasty (A.D. 25-220) it became more specific in the shique (石闕) and huaxiangshi (畵像石) in the Han dynasty (206 B.C.-A.D. 220). Afterwards, as Buddhism was introduced to China, the bracket construction techniques shown in the Mogao Caves, Yungang Grottoes, and Longmen Grottoes has given much help for understanding the building techniques of wooden architecture. Especially the Xia-ang structure seen in the Mogao caves shows a vast development in wooden structure and a typical building would be the main hall of Fo Guang Shan monastery in Mt. Wutaishan from the Tang dynasty (A.D. 618-907). This accumulated techniques is inscribed in the 'Ying Zao Fa Shi (營造法式)' wooden structure designs which was published during the Northern Song dynasty (A.D. 960-1127) and many buildings were constructed following this technique after the publication. During this period, it is assumed that Baek-jae (B.C.18-A.D.660) in the Korean peninsula also used the Xia-ang technique, but there havn't been many studies on this field. In this thesis it is introducing the development of the building techniques and structural features of the Xia-ang wooden architecture during the Tang and Song dynasty.
