  • Recently, as a result of the economic growth, the concentration of population towards the cities and the rise in land prices, the demand for high rise buildings has increased significantly, the trend to build high rise buildings such as the mixed-use development buildings by the domestic construction companies continues. It's very important what kind of form work system is applied on the Core Wall of the high rise buildings to determine the economic efficiency for the whole project. That's because the appropriate selection of the Formwork system enables the construction cost lower, makes the good quality of the finished concrete, reduces the construction period, assurance of safety, and further more, it enables to achieve the successful performance of the projects. Therefore, this research, after comparing the strength and the weakness between the construction methods, focus the point to provide a builder the basic data to choose the right Formwork method.

  • Recently buildings are constructed in larger and higher scales and becoming more complex. Every country in the world is competing to build high-rise buildings. Korea also has and is constructing high-rise buildings, like the 123story Jamsil Lotte Super Tower. However from small to large scale buildings and on construction sites there still are fire safety accidents that occur continuously. Therefore to improve fire safety plan, examining the actual fire safety management and understanding fire risk analysis Using Fire Modeling through Computer Simulation. Fire safety management plan related fire safety cases were collected an dan analyzed for the study. Also hazard analysis of High rise Buildings under fire compared with existing fire law sand regulations.

  • 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.

  • 최근 국내 외 대도시를 중심으로, 글로벌 경제 위기와 부동산 경기 침체로 중단되거나 연기되었던 초고층 프로젝트들이 재개되고 있으며, 이를 수주하기 위한 건설사들의 경쟁은 전보다 더욱 치열해지고 있다. 국내 건설사들이 초고층 건축 분야에서 경쟁력을 높이기 위해서는, 전체 프로젝트의 근간이 되는 중요한 요소인 양중계획의 체계적인 리스크 관리가 반드시 수반되어야 하지만, 여전히 개인적 경험에 의존하여 작성 된, 양중계획의 오류로 인한, 현장 전체의 공기 지연 및 원가 관리 실패의 문제가 빈번하게 발생하고 있다. 따라서 본 연구에서는, 양중계획의 정확성을 높이기 위한 방안으로, 현행 양중계획 체계의 문제점을 분석하고, 계획 요소에 따라 실패 유형을 도출하였으며, 각 실패 유형이 전체 프로젝트의 공정, 원가, 안전관리에 미치는 영향도를 분석하였다. 또한 양중 장비별 세부 리스크 요인을 분석하고, 이를 바탕으로 FMEA 기법을 적용하여 초고층 프로젝트 양중계획의 핵심 리스크 요인을 도출하였다.

  • Newly constructed, high-rise dense building areas by urban development can cause changes in local wind fields. Wind fields were analyzed to assess the impact on the local meteorology due to the land use changes during the urban redevelopment called "Eunpyeong new town" in north-western Seoul using CFD_NIMR_SNU (Computational Fluid Dynamics, National Institute of Meteorological Research, Seoul National University) model. Initial value of wind speed and direction use analysis value of AWS (Automatic Weather Station) data during 5 years. In the case of the pre-construction with low rise built-up area, it was simulated that the spatial distribution of horizontal wind fields depends on the topography and wind direction of initial inflow. But, in the case of the post-construction with high rise built-up area, it was analyzed that the wind field was affected by high rise buildings as well as terrain. High-rise buildings can generate new circulations among buildings. In addition, small size vortexes were newly generated by terrain and high rise buildings after the construction. As high-rise buildings act as a barrier, we found that the horizontal wind flow was separated and wind speed was reduced behind the buildings. CFD_NIMR_SNU was able to analyze the impact of high-rise buildings during the urban development. With the support of high power computing, it will be more common to utilize sophisticated numerical analysis models such as CFD_NIMR_SNU in evaluating the impact of urban development on wind flow or channel.

  • Flat plate structures are designed in the form of long span due to the development of construction materials and the improvement of construction technology. However, a high-rise structure of a flat plate of 50 less floors is constructed without detailed review of the inequality shortening, long-term deflection of the slab, and cracks. Therefore, it is possible to examine the case of defects in the structure due to deformation and damage of non-structures such as crack and leak, deflection of the door frame, and deformation of equipment ducts. In this study, it is a high-rise structure, and the inequality shortening and long-term deflection of the slab of the flat plate structure were evaluated through finite element analysis, and it was confirmed that prior precision analysis and correction during construction is necessary.

  • The increase of hish-rise residential-commercial buildings is required to cut down a term of works and the cost of construction. Reinforced concrete structures and steel framed reinforcement concrete that are commonly used have the difficulty in reducing them. Therefore, the purpose of this study is to propose a new precast concrete complex system and to analyze its economical feasibility. The economic analysis is performed through comparing the cost of a high-rise reinforced building that was already constructed with that of the new proposed precast concrete system, which is limited to structural frame work of typical floors. This study shows that the proposed precast concrete complex system is economical. Further research should be directed at including the influence of a term of works.
