In the late twentieth century, the multistory housing has become the most preferred housing type. Moreover, in multistory housing design, not only interior design but also exterior design, uniqueness and characteristic have been added as significant factors in design to break simplicity and uniformity. The purpose of this study is to understand the tendency of the elevation design in Europe and to suggest the idea for elevation design for domestic. Also, each elements of elevation were analyzed through classification and schematization which categorized by its own characteristic. Design elements can be classified into three categories. They are corresponding with inner spaces, emphasizing visual expression of exterior material and texture, and presenting aesthetic factors of building shape. Those are named as the Spatial Externalization, the Visual Expression, and the Expression of Building Shape. In this frame nineteen elevations of sixteen different cases were analysed. As a result of case studies, it is clear that elevation designs were not standardized and each cases has its own characteristics. Also it showed how the each design elements can be coordinated as a total design and how they expressed identities of each housing. This study could contribute to motivate diversifying the design of multistory housing.

A study on the traditional houses of North Korea(I) have been published in 1996. This paper is written to supplement the preceding paper. This paper aims at collecting new data of traditional house in North Korea. But still being prohibited for the researchers of South Korea to approach to the field, I had to depend on the memories and experiences of the immigrants from North Korea who are now living in Kangwon and Incheon Province. Through the questionnaire and drawings, they described vivid memory of their old houses. I was able to add new data of 70 cases, which are significant and valuable as much as those of the real field are. Those data, including the exisiting data, are enough for me to analize statstically the regional charateristics, the differnces among economical classes, and the periodical change. It opens the way for verfying the existing theory. Regional charateristics of house in North Korea can be described as followings: a. Hamkyong-do ; Concentrating spaces into one building, Double-fold type plan, Including 'cheongju-kan' space, Weak fences b. Pyongan-do ; Concentrating spaces into two buildings, 二 shape buildings , Single-fold type plan, Strong fence c. Pyongannam-do to Myolak mountains; Concentraing spaces into two buildings, ㄱ, ㄷ shape buildings, Single-fold type plan, Strong fence d. Southern area of Myolak mountains; Concentrating spaces into one building ㅁ shape building, Single-fold type plan with wooden floor space

Reinforced concrete structures require large amounts of concrete and rebar in the construction stage. Rebar is a major resource for reinforced concrete structures, and generates more CO₂ per unit weight than other materials. To solve this problem, it was confirmed that the cutting waste can be close to zero when the special length of the rebar is calculated in the drawing created after structural design. However, a system for automatically calculating the length of reinforcing bars to efficiently calculate the total amount of reinforcing bars has not been established. Therefore, the objective of this study is a basic study of automatic rebar length estimate algorithm of bearing wall by using BIM-based shape codes built in Revit. The bearing wall rebar can be automatically derived using the developed model. Furthermore, through applying the developed model to the construction field, it will greatly contribute to reducing greenhouse gas emissions by reducing rebar cutting waste.

Located in a rear garden of Changdeok Palace, Yeonkyeong-Dang is valued as the most characteristic building of the houses of aristocrats of the later Joseon Dynasty. The time of the construction has been much debated, however, it is perceived through this research that the construction was completed in September 1827(the 27nd year of king Sunjo's reign). The shape of the buildings during this period resembles a letter ㄷ as shown in the picture of Dong-Kweol. We previously described that the purpose of Yeonkyeong-Dang was to carry the portrait of king Yikjong while keeping the shape of building when it was first established until the 8th year of king Heonjong (1842). In 1865 (the 2nd year of king Gojong's reign), it was reconstructed with very different outlook which has remained the present shape. The characteristic features of the residences of aristocrats were reflected in newly reconstructed Yeonkyeong-Dang. The structure was largely divided into two quarters that occupied by male and female residents respectively. The two quarters were bordered by fences and added with a study and a pavilion. The reconstruction was conducted by king Gojong's father, Daewon- Goon and its purpose was to prepare a separate house for the king and queen before the kings wedding that was about to come. During the 19th century, building an imitation of houses of aristocrats became quite a trend in the palace. Built in 1847, Nakseon-Jae was precedented and followed by Yeonkyeong-Dang. Also later Geoncheong Palace was built in Kyeongbok Palace in 1873. All of the three buildings imitated houses of aristocrats. Divided residences of male and female sections and splendid decorations were common features. Nakseon-Jae was the smallest in the structure of spaces, ornamentation of details and its sizes, Yeonkyeong-Dang was the second and Geoncheong Palace was the most distinguished building. The constructions of these three buildings created an innovative architectural wave in the 19th century palace. Yeonkyeong-Dang was the building that mediated the new flow of architectural structure in the 19th century palace.

In the representation of buildings with continuous changes in the curved shape of the surface, countless plans or sections are required, or none of the traditional drawings can explain the geometry of it. In other words, in no case can an ordinary drawing achieve the efficient and clear communication capability which is inherent function of the drawings. As a result, the current architects are introducing their own way of drawing technique which is developed in accordance with a specific curved shape, construction method or company resources, but this is not what can be applied to other cases because it has not been ever shared or agreed in the industry. In this process, the drawing or construction of curved building has been recognized as the exclusive property of a specific expert, or the design and construction without the in-depth understanding of the technology have resulted in the appearance of poor buildings. Therefore, this study aims to present an elements and method that can convey shape information more effectively and clearly in the drawing representation of non-linear buildings and, thus, contributes to lowering the barriers to entry into the field by providing the information to be easily applied to related projects. In order to attain this goal, the drawings of recently completed projects of free form building are analyzed to reveal the method used to effectively express the shape information of the building and to derive new drawing elements that have not been applied to the existing drawings.

The history of tall buildings begins in 1853with the development of elevators. After the Industrial Revolution of the 18th century, the development of high-rise buildings will be carried out in earnest as a means to efficiently use the limited land of cities. The development, which began around Chicago, extended over a long period of time to Asia, maximizing the high competition. However, in the 2000s, not only was it high due to the development of construction and digital technology, but it also became competitive in eco-friendly elements and unstructured forms. High-rise building plans that have gained elemental and morphological diversity are completed by the interrelationships of various plans. Among them, it is important that the core plan has a reasonable approach from the initial planning stage as the basis for the vertical copper plan linking vertically-intensive functions. The cores should be designed to be clear and adequately responsive to changes in the shape of the building. This study aims to provide designers with a reasonable understanding of core planning by identifying core characteristics of irregular high-rise. In particular, we want to analyze the shape of the ground layer core and the relationship between the area and components of the ground layer core. The analysis results are as follows, classified according to the type or use of the building. Of the atypical forms composed of double bending, the TAPER-Curve and TWIST forms are the most distributed, and the plane and core shapes of the ground floor are the most commonly used. Based on the analysis of the validity of the ground floor cores by shape of the cores, the most commonly used forms for core shapes in the planning of the atypical high-rise are square, circular and Oval, and the most efficient oval cores and relatively inefficient ones when planned.

Purpose: Apartment is a typical residential type in Korea. In the past, apartment types were very monotonous. But today, the types of complex are changed because personal needs have been diversified and personalized. In order to meet those needs, construction companies are constructing various types of apartments. The more apartment types are diverse, the more the energy problems are taken place. So, the purpose of this study is to solve the problem of energy gap in the same complex through improving the thermal transmittance of wall. Method: Heating energy consumption of Building Energy Efficiency Rating System and heating energy usage of apartment show a similar trend on the graph. In order to identify the best position of heating energy consumption difference reduction, we change the building's U-value of front, back, side walls. Result: In the A complex, maximum and minimum heating energy consumption building's shapes are flat. the best efficiency is side U-value change and the worst is front change. In the E complex, maximum heating energy consumption building's shape is tower and minimum building shape is flat. Consequently, the front and back wall performance change was little effect to reduce energy gap, while the change of side wall's U-value show the great reduction between building's energy consumptions.

The Purpose of this is properties of CFT filled with expansion concrete. CFT(concrete filled steel tube) is the structure that circle shape steel column filled with concrete. 3 kinds of expansive additives and variation of replacement rate. we changed expansive additive from 0%, 10%, 20%, 30% of ratio of addition rate are selected for this experiment. Merits of CFT are concrete internal force rising influenced by steel shape restriction, reinforcing the local buckling, excellent resistance to transformation. Generally, High rise building using CFT utilize the high strength and fluidity concrete for packing the tube inside. As the result a steel tube charged expensive concrete has stiffness 1.5times more than a steel tube not charged concrete. Increase of resisting power about compressive stress by binding expansion of expansive concrete affects strength increase and softness.
