Very stiff floor system in a residential-commercial building causes some problems in the numerical analysis procedure due to significant difference in stiffness with adjacent elements. Static analysis of structure with a stiff transfer-floor can be performed approximately in two steps for upper and lower parts for the structure. However, it is impossible to perform dynamic analysis in two steps with separate models. An efficient method for dynamic analysis of a structure with a right floor system is proposd in this study. The matrix condensation technique is employed to reduce the degree of freedom for upper and lower parts of the structure and a beam elements with rigid bodies at both ends are introduce to model the rigid floor system. Efficiency and accuracy of the proposed method are verified through analysis of several example structures.

Most textbooks of urban geography explain that land value drops down with distance from the Peak Land Value Intersection of urban center. However, There is little rigorous empirical work supporting this belief. Using the publicly notified individual land price data of 2013, this paper examines the structure of land value in urban center with a focus on spatial distribution of land value by land use. As an analytic result, the structure of land price varies between land uses, significantly being different from the classical model of land value in urban space. In residential lands and mixed-use lands for residence and commerce, land price gradient as a function of distance from PLVI is positive and a crater phenomenon even is identified in spatial distribution of land value. The classical model coincides only with land for commerce and office. Nonetheless, predict of land uses by land value function fairly corresponds to Alonso's model.

대도시의 인구집중에 따라 토지의 고도이용을 위하여 건물의 고층화 및 복합화에 대한 요구가 점점 더 높아지고 있으며, 도심지에서의 삶의 질을 윤택하게 하기 위한 방법으로서 조망에 대한 욕구가 더 한층 중요시되고 있다. 이러한 이유로 인해 주거용 아파트에도 초고층 빌딩 개념이 도입되고, 상가 및 커뮤니티 시설 등이 추가되는 주상복합건물의 건설이 증가하는 추세에 있다.(중략)

The architectural difference between the existing residence and high-rise residential building causes changes on environmental conditions such as ventilation and insulation. The object of this study is to present the improvement on envelop of high-rise residential buildings to reduce heating and cooling load. To improve the environmental performance of envelop, it is necessary to modify envelop vent system and ensure intermediate space. In this study, the shape of vents in high-rise residential buildings has been inspected, and the survey about the interior environmental conditions related to the envelop of high-rise residential building has been conducted. Environmental measurement has been done to examine out door air quality for natural ventilation.

Recently, various building types such as Center-Core shape and Y-shape were studied as the demand for hight-rise residental complex increased. However, Center-Core type can make many Problems because the house unit can face to the north or west. Therefore, this study evaluated daylight conditions for four plan types in high-rise residental complex.

The purpose of this study is to examine the characteristics of unit plans in the high-rise mixed-use condominium and to provide the data fur architectural planning and design. The tools of statistical analysis are frequency, percentage, mean, cross-tab, and correlation. The results of this study are as fellows; The most frequently found shape of unit is a deformed polygon. The common rooms in housing units are dressing room, powder room, offset-kitchen, family room, passage, hallway, and foyer. The specially prepared spaces are wash room, home bar, independent porch, and garden. As to room size and area ratio in a dwelling unit, those of living room are biggest and highest irrespective of unit size. As the floor area of unit increases, does the size of each room and space but the area ratio of each room decreases. This research is made to develop an Apartment Information System. This integrated information system is to be designed to provide residents of high-rise mixed-use condominiums with convenient, economical, and safe life.

인천 청라지구는 송도, 영종과 더불어 미래 인천을 이끌 핵심 지역으로 꼽힌다. 이는 인접한 인천국제공항, 김포공항, 인천항 등을 통해 세계와 연결되는 교통과 물류의 요지인데다 녹지도 풍부해 최적의 업무 및 주거지역으로 손색이 없기 때문이다. '동북아시아 경제중심도시'를 꿈꾸는 인천의 포부에 큰 몫을 담당할 이곳은 현재 곳곳에서 공사가 한창이다. 내로라하는 건설사들이 실력을 발휘하는 가운데 그중에서도 단연 돋보이는 현장이 있다. 바로 우미건설이 최고급 주거단지를 목표로 시공하고 있는 '인천청라 린 스트라우스 주상복합 신축공사 현장'이 그것이다. '린 스타라우스 현장'은 총 4개동(41~42층) 590세대 아파트 및 450세대 오피스텔을 짓는 사업으로, 청라 최중심의 상업시설에 랜드마크 건물로 지어지고 있다. 견실한 우미건설의 브랜드에 더해준 수준 높은 시공능력도 세간의 이목을 받는 이유지만 이곳 현장이 주목을 받는 이유는 따로 있다. '물 샐 틈 없는 전방위 안전관리'로 사업시작이래 단 한건의 사고도 허락지 않고 무재해현장을 이어가고 있다는 점이 바로 그것. 무엇이 이곳을 우수 안전현장으로 이끌로 있는지 직접 찾아가 살펴보았다.

In a residential complex case, the efficiency of land use are maximized, but a variation of external condition such as load in-equality, the increase in wind velocity and solar radiation by a height causes increasing energy in a building. Besides, because of increasing window size for a lighting and a view, it comes heating load in winter and cooling load in summer. A choice of cooling-system is important for this reason. Recently an internal high-rise residential complex installs an air-cooling system and operates individual heating. However, this study applies water-cooling used one public cooling-tower instead of an air-cooling system, also with an efficiency test of an air and a water-cooling system, consider an internal applicability.

The purposes of this study were (a) to compare the level of sense of community and community activity of the mixed-use residential buildings' residents with the expected residents for the mixed-use residential building, (b) and to investigate the degree of their needs of social interaction. For the survey the questionnaire from 176 residents of mixes-use residential building in Seoul, and 67 expected residents in Bundang Newtown are used. The analytical methods adopted in this study were frequency, percentage, chi-square test and t-test. It was found that the level of sense of community and the community activities of the mixed-use residential building' residents were higher than those of the expected residents. Their residents reported higher degree of participation on community activities than the expected residents. It was also found that the common space in their residential area promoted the residents' sense of community and community activity.
