현대 산업사회의 과학기술 발달과 인구집중으로 인하여 기업의 경영조직 업무내용의 확대와 질적 변화에 의해 사무소 건축이 대형화, 고층화되어지고 있다. 특히 수많은 주체들과 분야들로 이루어진 고층사무소 사업을 수행하기 위해서는 사업 각 단계별 주요 정보에 대한 확실한 이해와 경험을 바탕으로 프로젝트 전 과정의 통합관리가 필요하다. 또한 건축계획 구조, 재료 및 시공성(Constructability)의 각 분야별 요소기술들이 효율적이고도 유기적으로 연결${\cdot}$접목되어야 한다. 그러나 설계와 시공간의 상호 인터페이스의 미비로 인한 설계와 시공업체 간의 노하우가 유기적이고 체계적으로 공유되고 있지 못하고 있으며 고층사무소 사업의 시공단계에 있어서 반복적인 문제점이 되풀이되고 있는 실정이다. 이에 본 연구에서는 고층사무소 사업의 시공성을 고려하지 않은 설계로 인해 골조공사의 시공단계에서 유사하게 반복적으로 되풀이되어 발생하고 있는 주요항목들을 파악하고 분석하여 해당 순위를 제시하고자한다.

Abeno Harukas is the tallest building in Japan and is located in Abeno, which is one of the three main railway transport nodes in Osaka. This building has a height of 300 meters, and its lowest levels are 30 meters below ground. It contains a department store, museum, offices, a hotel, and an observatory. In this urban renewal project, a section of the department store that encloses the station was dismantled and replaced by a supertall building complex, while infrastructure was simultaneously constructed, including: upgrades to the station and the existing department store, improved connections to the subway and pedestrian bridges, and a new pedestrian walkway over the road. In this paper, the ingenious erection processes, newly developed technologies, and precise construction management techniques are introduced for Japan's tallest building.

Along the subduction-zone of the western Japanese islands, large earthquakes are expected occur around the middle of this century, and long-period ground motions will reach major urban areas, shaking high-rise buildings violently. Since some old high-rise buildings were designed without considering long-period ground motions, reinforcing such buildings is an important issue. An effective method to reinforce existing high-rise buildings is installing additional dampers. However, a problem with ordinary dampers is that they require reinforcement of surrounding columns and girders to support large reaction forces generated during earthquake ground motion. To solve this problem, a deformation-dependent oil damper was developed. The most attractive feature of this damper is to reduce the damping force at the moment when the frame deformation comes close to its maximum value. Due to this feature, the reinforcement of columns, girders, and foundations are no longer required. The authors applied seismic retrofitting with a deformation-dependent oil damper to an existing 54-story office building (Shinjuku Center Building) located in Shinjuku ward, Tokyo, in 2009 to suppress vibration under the long period earthquake ground motions. The seismic responses were observed in the 2011 Tohoku Earthquake, and it is clarified that the damping ratio was higher and the response lower by 20% as compared to the building without dampers.

When the tall office building first appeared in the street of Chicago in the end of Nineteenth Century, this building type has become a commodity in the development of real estate and been defined as a machine that makes the land pay. With the investigation of land price samples of the high-rise commercial buildings and the overall land price development in the central district of International Settlement in Shanghai, this paper tries to examine the site selection and construction of high-rise commercial buildings have important positive effect on the land value development.

The high-rise building is a dramatic phenomenon and a powerful expression of architecture in the modern civilization. The architecture of these high-rise buildings has been developed with mutual contributions of architectural aesthetic form and advanced technologies. Architecturally the significant evolution of tall buildings from ancient towers is a "change of function" from some religious symbols to a commercial concept that has aesthetically become acceptable with the changing of modern society and culture driven by a technological evolution. Generally, this commercial function in the evolution of high-rise building is office where high-rise working style is simply a necessity to meet quantitative market demands since this style in major cities around world has been changed from low-rise to high-rise during the last several decades in influenced of the modern industrial society. To achieve optimum spaces with architectural aesthetics in the high-rise building, the design has become collaborative, requiring the input of architects, engineers, economists, and other consultants. Hence, architects must deeply understand the basic planning theories of high-rise buildings and try to find optimum planning between architectural aesthetics and other issues. For the approach, we can firstly start with measurement and analysis of the planning use situation for major planning issues of high-rise buildings in practice. Therefore, this study is to analysis Design Elements and to find commonly used planning strategies, tectonic, of high-rise building in practice. It will give a chance to confirm commonly used planning and then becomes the starting point of the planning development of high-rise buildings based on practical planning issues.

최근 국내외적으로 고층건축물에서 화재, 테러 등의 재난에 의한 연소의 확대로 인하여 재산 및 인명피해가 증가하고 있는 추세이다. 본 연구는 고층건축물에 대한 안전대책의 일환으로 고층사무용건축물에서 재실자의 피난행동예측 및 피난안전성평가를 위해 각각의 시나리오를 설정하여 피난시뮬레이션을 실행하였고, 그 결과데이터를 토대로 피난안전성을 평가하였다. 본 연구를 통해 얻은 결과 및 제안사항은 다음과 같이 요약할 수 있다. 첫째, 현재 경호경비분야에서 고층건축물 및 다중이용시설에 관한 연구는 질적인 연구에 그치고 있는 실정이며, 고층건축물에 대한 경호경비계획에서 심층 분석하고 다각도로 대비함으로서 구체적 실질적 체계적 합리적인 종합안전대책이 마련되어야 위기상황 발생시 피해를 최소화할 수 있다고 판단된다. 둘째, 고층건축물에 대한 경호경비계획에서 피난구획의 설정은 비상시 피난에 있어 영향을 미치는 요인으로 확인이 되었다. 셋째, 고층건축물에 대한 경호경비계획에서 복수 층의 동시 피난 상황을 고려하여, 층별 피난출구의 설정으로 전체 피난완료시간의 단축이 가능함이 확인되었다.

최근 들어 초고층 오피스 건축물의 건설이 크게 증가하고 있는 추세이며, 현재에도 많은 계획안이 추진중이며, 건설될 전망이다. 초고층 건축물은 건축물의 개념을 초월하여 도시의 개념을 지니고 있는데, 그 크기만큼 상당한 양의 에너지를 한 건축물에서 소비하고 있는 것이다. 따라서 초고층 건축물에서 소비되는 에너지를 절약하면 그 만큼 큰 효과를 볼 수 있는데, 공간에 적합하고 효율적인 조명설계와 시스템의 선택은 조명 에너지를 절약하기 위한 기초단계라고 할 수 있다. 본 연구에서는 국내 외 초고층 오피스 건축물의 조명설계 현황을 비교 분석하여 앞으로 건축될 초고층 오피스 건축물의 가이드라인으로 활용할 계획이다.

In Korea, buildings are becoming skyscrapers due to restrictions on land. The performance-oriented design was introduced in 2009 for fire safety of such buildings, but the application of the combustible data through engineering design and experiment is a poor reality. Large buildings are used for complex purposes, especially since the density of the office facilities is high, the study conducted a study on the combustible materials of the office facilities and the thermal speed and fire load of the main combustibles of the office facilities were calculated.

The objective of this study is to analyze and evaluate the impact of the stack effect in high-rise buildings for solving the various problems resulting from it. For the evaluation of the impacts on the stack effect, computer program simulations based on the network model were performed for a typical high-rise office building. The results of the simulations show that the impact caused by the stack effect is mainly dependent on building envelope air-tightness and internal air flow resistance. Therefore the problems due to the stack effect may be solved to some extent by installing vestibules around entrance doors and doors serving elevators, and by zoning the elevators.

This paper discusses the economics of skyscraper construction in Manhattan since 1990. First the paper reviews the economic theory of skyscraper height. Next it documents the frequency and heights of skyscraper construction in the last 25 years. Then the paper reviews the relative movements of office rents, condominium prices, and construction costs. Statistical results suggest that the resurgence of Manhattan's skyscraper construction is being driving by the rise in the average price of apartments, and is not being driven by rising office rents or falling construction costs. Statistical evidence shows that the height premium has not been rising over the last decade. Developers have been purchasing air rights (and bidding up the prices) in order to satisfy the demand for supertall buildings. In the next five to ten years, Manhattan is likely to see over thirty 200-meter or taller buildings, as compared to only four since 2010.
