The purpose of this study is to prove the correlations among various factors what determined to formation of front elevation proportion system through making an actual survey and investigating. According to the analysis of them, we make conclusions as follows; 1, On the assumption that average distance of 1Kan(間) is 1, the height of foundation is 0.21, the height of floor from foundation is 0.24, the height of normal column from floor is 0.85, the height of eaves from foundation is 1.10. 2. Southeast faced buildings are wider than southwest faced buildings in the distance of 1Kan (間) in the range of $110{sim}220mm$. The height of foundation and floor in the southeast faced buildings are higher than those in southwest faced buildings beside the height of normal column, eaves, high column in the southwest faced buildings are higher than those in southeast faced buildings. 3. As number of front Kan(間) increases, the distance of 1Kan(間) decrease and the height of eaves and high column(高柱) increases. This is cause of making a maximum needed inner space by increasing the distance of 1Kan(間). This is an wisdom for living from ancestors. 4. As number of Dori(道里) increases, the distances of 1Kan are nearly same but the height of eaves and high column(高柱) increases about 300mm, This is a natural result from an increasing of building scale. 5. The distance of 1Kan(間) in later 19C building is most wide but, the unit heights are minimal average values at year 1900 as a reference mark. After this, the height of normal column, eaves, high column are higher about $170{sim}330mm$. 6. The number of Kan in front elevation, Dori(道里), and direction of building have correlations each other in proportion system of traditional housing An-Chae with significant level, p<0.05.

본 논문은 고층건물의 지진응답해석에서 탄성 및 탄소성 응답스펙트럼 해석법에 대하여 고찰한 것이다. 선형 구조물의 지진응답 해석에 널리 사용되고 있는 응답스펙트럼법은 여러 연구자들에 의해 서로 다른 모드 조합방법으로 제안되었으며, 이들 조합방법에 따른 차이점을 상세히 검토하였다. 탄소성 지진응답해석에 응답스펙트럼법은 아직 널리 사용되고 있지 못한 실정이다. 본 연구에서는 장주기를 갖는 고층 건물의 탄소성 지진응답해석에 응답스펙트럼을 확장하여 적용하는 방법을 제시한다. 본 논문에서 제안한 탄소성 응답스펙트럼법을 이용하면, 고층건물의 예비 설계에서 시간이력해석 대신으로 보다 간편히 탄소성 응답치를 예측하는 도구로서 활용할 수 있을 것으로 사료된다.

The study on the government office building in Chungcheong Suyeong(忠淸水營) is very rare. How were the Gaeksa(客舍) and Dongheon(東軒) which are representative government office buildings in Suyeong, maintained and what was the aspect of it, while passing through the upheaval period of the end of Joseon(朝鮮)? And where was the original place and was there any change in use? It is so regrettable that these subjects were not figured out yet. So I thought it is very important task to figure out its actual aspect by investigating the maintain state of the Gaeksa and Dongheon and the change of their places. So this study examined the related historical records and, based on it, analyzed "Ocheon GoonJi(鰲川郡誌)" in various view points. Through this analysis, this study could figured out the maintain aspect of the gaeksa and dongheon and the change of their places, and be able to deduce the other change of the government office building. This study could assume the places of each government office buildings by comparing this investigated result and the analyzed result of the original cadastral map in various view points. As the result of the study done by this method, this study confirmed the maintain state of the Gaeksa and Dongheon in Chungcheong Suyeong while passing through the upheaval period of the end of Joseon. And this study figured out the places of the Gaeksa and Dongheon, and be able to confirm their places by the lot number on the original cadastral map. Along with this, this study could estimate Jo(趙) family's confliction with the residents at that time by verifying the lot numbers of the Sapaeji(賜牌地) which this family received from the government. And among the names of the government office buildings, for the Jangkyocheong(將校廳) which is in dispute because of the name, this study figured out that the author of "Ocheon GoonJi" made a mistake in writing Dongheon.

분단 70년을 거치며 남북한의 문화적 이질화가 가속화되고 있다. 이러한 상황에서 북한 주민의 일상생활에 대한 장기적인 아카이브 구축은 북한 이해의 폭을 넓히는 데 기여할 수 있다. 여기서는 일상생활을 "제도, 사회통제, 규범, 질서 등의 사회구조적 측면과 개인의 다양한 실천과 행위가 교차하는 사회적 공간"으로 규정하였다. 이 연구의 목적은 이러한 일상생활의 개념을 적용하여 북한 일상생활에 관한 증거와 기억이 풍부하게 담긴 아카이브 구축 모형을 설계하는 것이다. 이를 위하여 일상생활의 특징을 반영한 방법론이 필요한데, 이를 '문화 아카이빙'이라고 명명하고 그 핵심 개념을 정리하였다. 이러한 방법론을 적용하여 북한 일상생활 아카이브 구축의 원칙과 절차가 포함된 모형을 제안하였다. 또한 각 구축 절차가 어떻게 적용될 수 있는지를 실제 사례(북한 생활·문화·역사 데이터베이스)를 통해 살펴보았다.

구조물의 지진응답은 기초지반조건의 영향을 받는다. 이 연구에서는 고정지반과 연약지반을 고려한 3, 5, 7층 철골 건축구조물의 밑면전단력을 산정하기 위해 선형 시간이력지진해석과 비선형 Pushover 정적지진해석을 수행하였다. 등가정적강성식으로 구한 기초지반강성은 SAP2000의 Link 요소 중 Damper 요소를 사용하여 입력하였다. 범용구조해석 프로그램 SAP2000에 의한 시간이력으로 구한 철골건축구조물의 밑면전단력을 국내내진설계기준, UBC-97 설계응답스펙트럼, Pushover 정적 비선형해석으로 구한 밑면전단력과 비교하였다. 중력하중과 풍하중으로 설계된 철골 건축구조물은 0.11g의 중진에 대해 탄성응답을 보였고, 탄성 연약지반에서 구조물-지반의 상호작용과 지반 증폭에 의해 구조물의 변위와 밑면전단력이 증가되었다. 따라서, 중약진 지역에서의 건축구조물은 연약지반의 특성을 고려하여 탄성지진해석을 수행하는 것이 더 합리적이다.

Rocking motion have been used for achieving the 'resilient buildings' against earthquakes in recent studies. Low-rise buildings, unlike the tall ones, because of their small aspect ratio tend to slide rather than move in rocking mode. However, since rocking is more effective in seismic response reduction than sliding, it is desired to create rocking motion in low-rise buildings too. One way for this purpose is making the building's structure rock on its internal bay(s) by reducing the number of bays at the lower part of the building's skeleton, giving it a mushroom form. In this study 'mushroom skeleton' has been used for creating multi-story rocking regular steel buildings with square plan to rock on its one-by-one bay central lowest story. To show if this idea is effective, a set of mushroom buildings have been considered, and their seismic responses have been compared with those of their conventional counterparts, designed based on a conventional code. Also, a set of similar buildings with skeleton stronger than code requirement, to have immediate occupancy (IO) performance level, have been considered for comparison. Seismic responses, obtained by nonlinear time history analyses, using scaled three-dimensional accelerograms of selected earthquakes, show that by using appropriate 'mushroom skeleton' the seismic performance of buildings is upgraded to mostly IO level, while all of the conventional buildings experience collapse prevention (CP) level or beyond. The strong-skeleton buildings mostly present IO performance level as well, however, their base shear and absolute acceleration responses are much higher than the mushroom buildings.

This study examines the design intent and the construction background of the UNESCO House in Korea planned in the 1950s, with a focus on the initial plans of the House by Kuzosa Architects & Engineers in 1959. To this day, the House has been evaluated as a representative example of an office building in the 1960s, and an early case of introducing curtain walls in Korea. However, only its technical characteristics have been explored with less emphasis on further research data. This study attempts to demonstrate the social and cultural expectations and the demands of the construction of the House by examining the documents produced at the time and the initial plan. This study also highlights the fact that the House was the first project of the architect Pai Ki Hyung to realize high-rise reinforced concrete construction in Seoul's dense center. In the 1950s, the House was planned as a modern building with a complex of various cultural facilities and offices due to the character of activities of the Commission, and the lack of public cultural facilities in Korea. The plan of the Kuzosa Architects & Engineers was selected through a design competition held in 1959. The House was completed in 1967, which took about eight years from planning to completion with design modification in the 1960s. The initial plan submitted before the design modification shows that Pai used the vocabulary and logic of modern architecture and planned the House not as a simple office building but as a complex cultural facility.

Since the beginning of the second Sino-Japanese war in 1937, the entire Korean Peninsula has entered a full-fledged wartime system. Japan enacted laws that strongly regulate the distribution of various resources for war, and the same was implemented in Joseon. In particular, as iron, copper, lead, tin, and aluminum were mobilized as raw materials for military supplies such as weapons, private distribution decreased significantly, which had a great impact on the construction industry. As the use of metal such as steel as building materials requires permission from the provincial governor, it has become difficult to supply and demand except for some military facilities. In addition, the Japanese Ministry of Commerce and Industry encouraged research and development and manufacturing to promote the so-called "substitute goods industry" to make up for the shortage of supplies. Products with improved performance through chemical treatment by injecting only a small amount of the same raw material than before or using alternative raw materials have been developed. It was intended to overcome the limitations of lack of raw materials through the chemical industry. In terms of building materials, various substitutes were produced due to the incorporation of petrochemicals and the use of synthetic resins. This trend continued even after the end of the war and served as one of the backgrounds for R&D and production of new materials without returning to the "substitute goods."

This study analyzes the response of a tall building with an H-shaped cross-section when subjected to wind loading generated by the same H-shape. As normative standards usually adopt regular geometries for determining the wind loading, this paper shows unpublished results which compares results of the dynamic response of H-shaped buildings with the response of simplified section buildings. Computational Fluid Dynamics (CFD) is employed to determine the steady wind load on the H-shaped building. The CFD models are validated by comparison with wind tunnel test data for the k-ε and k-ω models of turbulence. Transient wind loading is determined using the Synthetic Wind Method. A new methodology is presented that combines Stochastic and CFD methods. In addition, time-history dynamic structural analysis is performed using the HHT method for a period of 60 seconds on finite element models. First, the along-wind response is studied for wind speed variations. The wind speeds of 28, 36, 42, and 50 m/s at 0° case are considered. Subsequently, the dynamic response of the building is studied for wind loads at 0°, 45°, and 90° with a wind speed of 42 m/s, which approximates the point of resonance between gusts of wind and the structure. The response values associated with the first two directions for the H-shaped building are smaller than those for the R-shaped (Equivalent Rectangular Shape) one. However, the displacements of the H-shaped building associated with the latter wind load are larger.
