Differential shortening of vertical members in high-rise buildings affect other structural members that have to be considered such as horizontal members and exterior cladding. of many elements which affect the total amount of shortening, different loading history mainly comes from the different construction time. Shortening of 66 story concrete columns were investigated and compared according to the different construction time, little difference was found between the total shortening of interior and that of exterior column.

프로젝트 초기단계에서 신뢰도 높은 공정계획을 수립하고 공사기간 산정을 정확하게 하는 것은 공사 지연을 예방할 수 있으며, 연속적으로 발생하는 의사결정을 신속하고 정확하게 내리는 데 도움이 된다. 특히 초고층 프로젝트의 경우는 작업이 복잡하고 공사비가 크기 때문에 공사기간을 정확히 예상하는 것이 어렵고 공사지연시 발생하는 손실이 막대하다. 따라서 월별 작업가능률을 정확히 예상하고 적용하는 연구가 매우 중요하며 이는 초고층 프로젝트의 성패와 직결된다고 할 수 있다. 하지만 고도가 높아질수록 기후 환경은 지표면 근처와 차이가 생기기 때문에 일반적인 프로젝트의 작업가능률 산정방법은 초고층 프로젝트에서 정확성이 떨어지게 된다. 따라서 본 연구에서는 작업높이에 따라 변하는 기후요소 변화를 예측하여 이를 적용하여 높이에 따른 작업가능률을 산정하고, 각 지역의 기후특색에 따른 결과를 비교 분석하였다. 산정된 결과에 따르면 작업고도가 높아질수록 부산, 인천, 서울 순으로 작업가능률이 떨어졌으며, 이는 풍속의 영향이 가장 컸다. 이러한 작업높이를 고려한 지역별 작업가능률 산정은 향후 초고층 프로젝트 공사기간 산정업무, 타당성 조사, 대상 지역 선택 등에 활용될 수 있을 것으로 기대된다.

In Korea, starting with the Busan residential-commercial fire in 2010, the frequency of fire expansion in high-rise buildings has been continuously increasing. In the case of such large-scale fires, most of the fires generated from the inside tend to expand to the upper floors by riding the exterior material or exterior wall panels through the process of being ejected to the outside. It has been revised so that combustible exterior materials cannot be used in buildings. However, due to the legal fluoride level, the fire risk of high-rise buildings is still high, such as the case of a 33-story residential-commercial fire in Ulsan. In order to prevent such fire expansion, it is considered that it is necessary to first understand the nature of the fire occurring inside and the mechanism of the fire expansion in the upper floor. The purpose of this study is to propose improvements in domestic fire safety design through a review of existing literature to prevent fire expansion of high-rise buildings.

노후 고층아파트의 재고 확대로 이에 대한 대안으로 재건축과 리모델링이 제시되었다. 재건축사업은 물리적인 노후화보다 기능적, 사회적, 경제적 노후화를 이유로 실시되어 주택의 조기 멸실에 따른 사회적 비용 증대 등 여러 가지 문제점이 제시되었다. 이에 재건축에 대한 규제는 강화되고 리모델링 관련 제도가 개선될 예정이다. 리모델링 사업의 경제성 분석에 대한 기존의 연구가 강남과 잠실 등 개발이익이 큰 곳에 편중되어 있었다. 본 연구에서는 비도심지 아파트 소유자의 입장에서 재건축과 리모델링 시 경제성 검토에 대한 하나의 안을 제시해보고자 한다.

In order to determine the violation of right of light impact at adjacent residential area by high-rise building, analysis on the right of light for high-rise residential commercial complex building block at Gahngnam-ku, Seoul, Korea was carried out using Google Sketchup Pro. After the analysis th sunshine duration of B apartment decreased from 5 hours 16 minutes 3 hours 48 minutes by I hour 42 minutes after construction. It shows that the total sunshine duration is less than the Seoul City Government Standard which is more than 4 hours a day, or more than 2 consecutive hours. Lowering the heights of apartments by 54m would increase the total sunshine duration which would meet the Seoul City Government Standard by four hours seven minutes. Problems that rna lead to the violation on the right of light in the adjacent area should be discussed in advance and minimized by analyzing the right of light among buildings and structures which are scheduled to be constructed on the site during construction penni! process when high-rise building is proposed.

건축 프로젝트가 대형화 되어감에 따라 현장에서는 총체적인 관점에서 프로젝트를 관리할 수 있는 능력이 중요하게 인식되고 있다. 초고층건물공사는 그 규모로 인해 생산성 저하의 위험이 상존한다. 특히 관리대상 프로세스가 기타 공정에 비해 상대적으로 많은 마감공사는 생산성 유지 혹은 향상에 집중적인 관리가 요구된다. 즉, 골조공정의 생산성이 높더라도 마감공사의 생산성이 낮은 경우 전체 프로젝트의 생산성은 현저히 낮아지기 때문이다. 본 연구는 문헌고찰 및 인터뷰 둥을 통해서 초고층 건축공사의 마감공사 발주방식 선정요소를 도출하였으며, 이 요소들은 초고층건물 마감 공사의 발주방식에 어떻게 영향을 미치는가를 분석하기 위한 토대를 제공하고 있다.

Designed by star architect of Moshes Safdie, Raffles City Chongqing includes a total of 6 mega high-rise towers 250 to 380 m tall, a sky conservatory, a 5-storey high shopping mall and a 3-storey basement car parking. Located at the confluence of the Yangtze and Jailing Rivers, the site for the project is imbued with a significance that is immediately symbolic, both as a sign of Chongqing's important past and as a vivid indicator of the city's thriving present and future. The design for the project to be situated at this gateway takes as its governing idea the image of powerful sails upon the water. The outer facades of the project's eight towers - the transparent surfaces that will face the water to the north - are meant to recall a fleet of ancient Chinese ships, with their huge rectangles of white canvas filled by the wind. This is a $1.13million\;m^2$ mega scale integrated project of office, retail, hotel, service residence and high-end residence with the transportation hub and traffic circulation at various levels of the project. This paper presents the multi-dimensional hybrid design, engineering and construction of this mega scale project. The innovations and the cutting-edge technology used in this project are introduced and discussed benchmarking the design and construction of the skyscraper cluster in a major city like Chongqing of China.

Construction industry has become higher, larger and more complicated. It has been analyzed that the process planning in the construction site has been made by the site engineer experience mostly and some were made based on historical data. However, such plans have been investigated that require numerous revisions during construction which means that the plans made through such methods are not reliable. Numerous studies in this field have been conducted trying to solve such problems developing methodologies to overcome such limitations. It has been analyzed that many studies have focused on suggesting prediction models only that cannot be used for both actual planning prior to construction and process monitoring during construction. Therefore, this study suggests a methodology that effectively manages construction productivity by applying simulation methodology combined with bayesian approach focusing on the high-rise curtain wall operations.

Top-Down construction is becoming a popular construction method in China as there is a growing need for building high-rise structures in crowded urban areas. This paper deals with the explanation and analysis of characteristics of Top-Down construction in China. In China, usually construction site is relatively large or sometimes huge compared to that in Korea. Thus, as the high-rise portion of the building needs to be constructed first and fast, island method is used at the center p망t of the building. In the meanwhile, the remaining area of the building is constructed using Top-Down method to provide working area for equipments and workers. Also, the case studies of construction examples are provided in this paper. The purpose of this paper is to promote international understanding and interaction between neighborhood countries for the utilization of Top-Down construction.

Recently, the high-rise apartment housings have become a prototype of the urban residential dwelling in Korea and the numbers of one have steadily been increasing. According to this trend, the strength of the construction materials is also fortified to assure the stability and durability of the buildings. Specially, Re-bar of SD500 type is largely used at the construction sites of high-rise building. This study analyzes the current usage of SD500 high-strength re-bar at domestic construction sites. Through the result of this analysis, we develop Economic Evaluation Model that measure economic efficiency of lap splice and coupler splice, which are most commonly used in connection SD500. The evaluation method was applied to construction sites in Seoul in December 2006, and the result revealed that coupler splice is relatively superior in terms of cost efficiency when the re-bar diameter is longer and the concrete strength is lower.
