This paper intended to propose the optimal outrigger position in tall building. For this purpose, a schematic structure design of 70 stories building was accomplished by using MIDAS-Gen. In this analysis research, the key variables were the stiffness of outrigger, the stiffness of frame, the stiffness of shear wall, the stiffness of exterior column connected in outrigger and the outrigger location in height. With the intention of looking for the optimum location of outrigger system in high-rise building, we investigated the lateral displacement in top floor. The study proposed the new method to predict the optimal location of outrigger system considering the frame stiffness. And it is verified that the paper results can be helpful in providing the important engineering materials for finding out the optimum outrigger position in tall building.

Recently, The use of the curtain wall method is increasing in construction. The curtain wall construction is widely applied to the exterior wall of the building for shortening construction period and economical efficiency. However, the replacement of deterioration of the weather resistance and structural behavior of the sealing material connecting the curtain wall method and the glass frame is necessary for introduction of the stable curtain wall method and quality improvement in accordance with KS F 4910 standard. In this study, the elastic restoring force test was performed in the external environment. In this study, the deterioration of the sealant was evaluated for structural sealants. In Korea, studies on the variable displacement behavior of structural sealants are lacked. In this study, the reproduced results in laboratory conditions are compared with the deteriorating conditions exposed to the external environment, and they are reflected in the design of sealing materials in the future. According to the results of the study, it was confirmed that the existing structure sealant meets the quality standard of KS F 4910, but in the conditions performed in this study, adhesion failure of the specimen and cracking of the surface occurred. Especially, in the weather resistance test, it is necessary to evaluate the long-term durability performance of the structural sealant used in the curtain wall method by checking the insoluble state of all the test pieces. Therefore, in order to apply a conventional structural sealant to the site, it is necessary to introduce another durability performance evaluation.

Modern architecture and design show experiments that practice exchange and convergence with other genres through expansive thinking. This study aims to propose the use of graphic skins as a means of dematerializing and invisiblizing expressions of architecture. The method of realizing 'invisible architecture' can be largely divided into methods that use materials that manipulate light and graphic approaches based on trickery techniques. The exterior wall graphic of the special stage in Seoul Plaza can be said to be an attempt of dematerialization to make the building structure light and transparent, and a case to propose the role of super graphics to maintain the identity of the original place by erasing disharmonious elements from the field of view. It is expected that the graphic skin will be used as a powerful means of expression in the era of 'invisible architecture' as an effective camouflage method and media beyond the means of decorating the exterior walls of the completed facilities.

This paper studies the leakage situation of domestic residential building underground parking lots and main leakage areas. 18 complexes were studied and the results showed that 80% of buildings with exterior waterproofing had no leakage, but all buildings with interior waterproofing had leakage. According to a survey among professionals, water leakage problems are considered to be severe in underground parking lots and a preventative measure is required by the government. By comparing the survey and the actual situation at hand, the results showed that the lowest floor slab, wall construction joints, and floor expansion joints were the most prone to leakage. Based on the results, further study to develop a design manual for the appropriate prevention of leakage is deemed necessary.

Until 1980s, Korean elementary school architecture has been stereotyped by standard drawings. But there have been very few researches focused on this subject, especially regional one. As an attempt to improve these conditions, this study reviewed standard drawings of elementary school architecture by Education Board of Seoul in 1964 and 1975. Both standard drawings were reviewed through items such as components making a set of standard drawings, floor plan, elevation design and subsidiary facilities. They have rectangular unit classrooms, single-corridor block plan and plain exterior having no symbolic images, which are the characteristics of typical Korean school architecture until 1980s. On the other hand, they reveal the unknown characteristics such as double-corridor block plan, classrooms in basement, toilets of conventional type placed on every floor and changes in details of openings and exterior wall.

In these days, restaurants are not simply used as a physical space but used as a cultural space in which people can enjoy and experience different cultures and traditional images. Moreover, from the restaurants design elements which help to form the atmosphere of the restaurants which serve food of specific country, we can see the history and traditions of that country. The additional value of the traditional decorative components which are the main factors forming the atmosphere of the restaurant will be different according to the various expressions used in the restaurant space. For this article, 12 restaurants, Norangjugory korean restaurant, Yongsusan korean restaurant, Best well-bing food restaurant, Awoolim, Mugunhwa, Ondal in Korea, and Songhelou, South Beauty, Xuxian restaurant & lounge, Beijing dadong roast duck restaurant, The horizon chinese restaurant, Dynasty jade garden in China, were selected for the field study. This study focused on a comparative analysis of the traditional decorative elements, especially, the application rate of the traditional decorative elements. The analyzed elements are nature, religious beliefs, history and culture for the intangible elements and facade, courtyard, trademark, ground, wall, ceiling, door, window, furniture and adornment for the tangible elements. After that, we analyzed the rates of the use of traditional decorative elements and modern decorative elements. Through the survey result and ratio analysis, we concluded as below. In Korean restaurant, traditionality is expressed in furnitures while, in Chinese restaurant, traditionality is expressed in decorative pattern. When it comes to the intangible elements among the traditional decorative components of the Korean and Chinese restaurants, Chinese and Korean restaurants have similarities in emphasizing the natural elements. Korean restaurants focus much on the environmentally friendly parts, while Chinese restaurants focus much on the fantastic natural atmospheres like those shown and expressed in the poems. As for religion characteristics, Chinese restaurants emphasize "geomancy" more than Korean restaurant. When it comes to the visible elements among the traditional decorative components of the Korean and Chinese restaurants, in Korean restaurants, the interior part has more traditionality than exterior part, while in Chinese restaurants, the exterior part has more traditionality than the interior part.

Frank Lloyd Wright, a master of the 20th Century Ar-chitecture, contributed tremendously in creating a wholly new form of American architecture called Prairie Style. His idea behind the development of the building structur-al system, organic relationships between inner and outer space, horizontal vertical lines, and idea of extending and expanding interior spaces came from nature. He had completed over 390 projects throughout his life and 90% of those projects were residential design. The most typical characteristic shared by many of his residential design was that each design element, whether it is functional or aesthetical, has close relationship to or-ganic nature, human scale, theoretical floor plants, and maximum emphasis on horizontal lines in respect to na-ture. His concept of "flow of spaces" reformed common the-ory of room next to room in a enclosed space. His sense of "wall" was no longer the side of a box. Careful selec-tion of finishing materials, colors, and natural images en-hance the design as well. F.L. Wright was an artist, designer, and architect who believed the exterior space should have direct relationship to the interior space. His architectural philosophy was not only to design exterior of architecture but also to ful-fill his space through the careful development of interior elements such as furniture, and lighting fixture. Even the patterns for leaded glass windows were designed to have unified appearance from outside to inside of the house. The objective of this study was to analyze floor plans, spatial organizations, and interior design elements of the houses which represent the best of F.L. Wright's design principles and philosophy behind Prairie Style. The meth-od used to collect informations for this study was based on books, articles, journals, and actual site visits. actual site visits.

This study focused on the composition of the exterior space of Parkjinsagoga, the types of gardens and planting and the landscape characteristics of walls, and examined its meaning as modern garden remains. Parkjinsagoga is a modern Korean house that harmonizes traditionality and practicality, and is an invaluable material for research not only on architecture but also on changes in the gardens of upper-class gardens. Its exterior space can be divided largely into An-chae (inner house), Outer Sarang-chae (outer house) and Inner Sarang-chae areas, and a garden was created in each yard (inner garden). In particular, one thing noticeable is that the yard of Inner Sarang-chae, unlike traditional gardening styles, was actively decorated. At the center of the yard of Inner Sarang-chae, two atypical planters and artificial moundings were created and the traffic line of the garden was designed to enjoy them while walking. An atypical pond was created on one of the artificial moundings and trees and shrubs were densely planted. Natural stones were also placed. The style seemed to be affected by Japanese gardens. These characteristics observed in the gardens of Parkjinsagoga are closely related to the transitional characteristics that traditional gardens started to show in modern times. A total of 35 families and 57 species were planted in the gardens of Parkjinsagoga and there were 19 species of tall trees, 20 species of shrubs and 17 species of flowering plants. The number of species planted in the garden of Inner Sarang-chae was the highest, and a total of 22 species of tall trees and shrubs. The walls in Parkjinsagoga were basically earth and rock-fill walls but their materials and patterns differed depending on the type of spaces. Four types of walls were found to be introduced to the house.

Recently, the insulaton design standards for reducing the energy use of buildings have been strengthened. Althoug insulation work is the most cost-effective method for reducing the primary energy consumption per unit area of a building, there are no evaluation criteria for insulation performance at the time of construction and completion inspection. The purpose of this study is to provide objective data by establishing a standard for an analysis method and a method for easily experimenting with the exterior wall thermal transmittance of an apartment house using a thermal transmittance measuring device(TESTO 435). For the exterior wall of the test subject, the specific heat per unit area exceeded 20kJ/(m²·K), and the data at the end point suitable for ISO 9869-1 were analyzed by the average method. The measured values of the thermal transmittance for 3 consecutive days converged within +5% of the desing value, and the standard deviation of the thermal transmittance by day decreased in the order of 1-Day > 3-Day > 2-Day. The standard deviation of the thermal transmittance by time period decreased in the order of 00:00~24:00 < 19:00~07:00 < 00:00~07:00. The measured value of the thermal transmittance for the time perion of 00:00 to 07:00 per day almost coincided with an error of -3% to + 2% compare to the desing value.
