The High-rise building has a problem the ventilation performance of natural ventilator by stack effect that it occurs by pressure difference. For that reason the study about natural smoke ventilator of High-rise building consistently needs. Therefore on this study does analysis of difference with abroad through investigate of Natrual smoke ventilator's law, it conducts of natural smoke ventilator's research on the actual condition. As a result on this study, in the case of abroad that it states more specific standards than domestic. Also the result of a field study, it shows that the natural smoke ventilator is installed same size and the number regardless of building's pressure difference.

Recently Korea has imported and executed Performance Based Design for the method to settle the dangerousness on outbreak of fire of high-rise building. The overseas country's PBD is autonomic but It is unable to carry out the essential role of PBD as the performance based design that based the code based design in the domestic. Also It occurs the problems that different the classification standard of building as dualisation between the building code and the fire services act. In this study, We have investigated overseas's cases for the PBD of high-rise building and have drawn the improvement direction & the problem of domestic's PBD by comparing and the analysing the domestic regulation.

As buildings become taller and more complex, the number of high-rise and underground complex buildings is increasing, but risks are also increasing due to the limitations of existing evacuation safety methods. Through this study, we will analyze the fire and evacuation characteristics of high-rise and underground complex buildings, identify problems with the current evacuation safety method, and seek ways to improve them using digital technologies

최근의 건축공사는 고층화되어 가는 추세이며 원가절감과 공기단축, 생산성 향상 등이 요구되고 건설자동화의 도입을 통한 총생애자동화시스템의 도입이 시급히 요구되는 추세이다. 이에 따라 본 연구에서는 초고층 빌딩 건축에 주로 사용되는 커튼월 공법과 제조업에서의 SCM기법, 최신의 RFID기법을 이용하여 초고층 건축물 커튼월의 자동화 관리시스템을 구축을 위한 방안을 제시하였다. SCM기법이란 생산에서 판매에 이르는 전단계의 과정을 연결, 관리하는 것을 의미하고 커튼월은 빌딩 건축에서 골조공사의 공기단축과 단순화를 위해 가장 많이 활용되는 건식공법으로 건설공사에서 가장 제조업에 가까운 형태의 공사로 볼 수 있다. 또한 RFID는 SCM의 구현방법으로 자재의 흐름과 생산프로세스, 그리고 정보관리 시스템의 도구로 사용되며 이들을 활용한 총생애자동화시스템은 생산과정 뿐만 아니라 사후관리 과정에도 효율적이며 높은 생산성과 경제성 향상에 기여한 것으로 기대된다.

As high-rise buildings with 100 or more stories are being constructed, it is inevitable to use high-performance materials including high-performance concrete. What is most important in high-performance concrete is extremely high strength in order to reduce the section of members in high-rise buildings. During the last several years, there have been active researches on Ultra-high-strength concrete. While these researches have been mostly focused on strength development, however, other accompanying physical properties have not been studied sufficiently. Thus, this study purposed to obtain and analyze data on the physical-mechanical properties of Ultra-high-strength concrete through experiments and to use the results as basic information on required performance of concrete used in high-rise buildings.

초고층건축물의 수요가 증가하고 수요지역이 확장함에 따라 초고층건설 기술력향상의 필요성이 증가하고 있다. 또한, 건물의 초고층화로 인해 마감공사는 프로젝트전체에 영향을 미치는 중요한 관리요소가 되고 있다. 이에 본 연구는 마감공사 준비작업의 의사결정 및 수행을 지원하기 위한 도구로서 현장사진기반 공간모델을 제안하고 있으며, 그 구축방법을 제시하고 활용방안을 모색하고자 하였다. 현장사진기반 공간모델을 통하여 초고층프로젝트의 특성과 공종에 맞는 공간모델을 활용이 가능할 것으로 예상되며, 이를 통하여 건설분야에서의 공간모델 실용화를 기대할 수 있을 것이다.

Execution of the finish work for high-rise residential construction occurs when a mixture of work progresses simultaneously at each floor or sector and is carried on by highly-specialized subcontractor teams. Therefore, the finish work plan requires an effective scheduling method that interfaces between the work and the teams. In order to address these issues, the TACT technique is utilized in Korea. This technique is based on Line-of-Balance and Lean construction. However, according to recent case studies, finish work using TACT technique was frequently delayed with cost overruns because the work was performed without a detailed schedule control plan outlining the relationship between architecture and mechanical, electrical, and plumbing work. This paper describes the enhanced-TACT technique which provides a detailed work flow chart and TACT work template. With improved TACT technique, this paper will contribute to improved cash flow and reduced cycle time and provide quality improvement through work continuity.

High-rise buildings move during construction due to time-dependent material properties of concrete (creep and shrinkage), construction sequences, and structural shapes. The building movements, including vertical and horizontal displacements, result from the sum of axial and lateral deformation of vertical members at each level. In addition to the vertical shortenings, the lateral movement induced by differential shortening can have adverse effects on the construction tolerance and serviceability of non-structural elements such as elevators and curtain walls. In this study a construction stage analysis method is developed to predict lateral movement induced by shortening, including the effect of creep and shrinkage. The algorithm of construction stage analysis is combined with the FE analysis program. It is then applied to predict lateral movement of a 58-story reinforced concrete building that was constructed in Kuala Lumpur, Malaysia. Gravity induced lateral movement of this building is predicted by the construction stage analysis. A field three-dimensional laser scanning survey is carried out to verify the prediction results, and satisfactory agreement is obtained.

The bi-directional high pressure pile load test(BDH PLT) which is a kind of pile load tests was conducted to find out a reasonable design procedure of large-diameter drilled shafts of large-size building structures. The behaviors of bearing capacity and settlement of the large-diameter drilled shafts were analyzed and the results obtained from BDH PLT were also compared with those obtained from the equations suggested in the specification. In case of the reasonable design procedure adopted, the construction cost could be saved at least 15 ~ 28%. It could be concluded that BDH PLT should be needed for the foundation construction cost reduction of the high-rise building structures.
