  • In recent years, many high-rise buildings have been constructed for the purpose of redevelopment of urban environments in Korea. However, generally the construction durations do not increase in proportion to the number of the floors or the height of the building. So new materials, equipments, and methods are applied to high-rise building construction in order to overcome this problem. In most cases, applying these new resources is considered mainly as the technical issue, and the organizational aspects of this is frequently overlooked. This study discussed the performance variance in time and identified the causes of time variance in high-rise building construction from organizational viewpoint .

  • In this study, the wind pressure was measured using multiple pressure measuring systems for high-rise buildings with modified edges. The pressure patterns that could occur on the surface of high-rise buildings were investigated through Independent Component Analysis (ICA). The power spectrum density was then evaluated using each mode obtained through the ICA. In the first mode of the ICA, it is possible to identify the shear layer caused by the blowing up. Even if the high-rise building was facing towards the direction of the wind, negative pressure were identified on the corner surfaces of the high-rise building. In the second mode of the ICA, it is identified that the vortex appears to be stronger on the wind-facing edge surface. Furthermore, power spectrum densities were also used to identify the vortex phenomena occurring in secondary mode of the ICA.

  • The overall ability to manage the construction projects from an integrated perspective is important due to the emerging of high-rise building constructions. Potential hazardous of low productivity exist in the finishing work of high rise building a distinct example of the projects. Especially, the number of activities that should be controlled during finishing work is more than during skeleton work. Thus field managers should attract more attention to manage finish work activities. The low productivity of these activities can diminish that of skeleton work. Decision factors of the delivery system for finishing works in the high-rise building project is established by means of literature review and questionnaire survey and a basis to analyze the effects of the criteria to the deli very system is presented.

  • Although steel-reinforced concrete(SRC) is widely used in a high-rise building, a methods used to predict the column shortening of SRC structural members has many problems in applying a theoretical equation which considers only the material characteristics of reinforced concrete. In this study, the degree of accuracy of the existing method calculating the column shortening of a high-rise building is examined. For this, first, the actual measurement data are chosen about the column shortening of a high-rise building established with SRC structural members. Then the column shortening of a SRC structural member is calculated through computer program. Finally, the comparison between the measurement data and the analytical ones is executed. According to this study, it can be concluded that there is little difference between the former and the latter. Therefore, the existing method can be used to evaluate the column shortening of a high-rise building using a SRC structural members.

  • Fire is recognized as a significant hazard in a service life of a structure. Therefore there is a clear need to provide an improved understanding of the performance of material and structures in fire and to provide clear design guidance in order to progress safety design especially high rise building. It is the aim of this study to investigates and analyze the study on the development of evaluation methods for fire risk analysis of high-rise building.

  • Due to recent trends of the atypical plan shapes and the zoning construction in high-rise buildings, the building stability under construction is arising as an important issue for design and construction plan. To ensure the stability under construction, the differential column shortening and the lateral movements with unbalanced distributions of self-weight of structure members and the load flows before completion of member connections and lateral load resisting system should be checked by construction sequence analysis. This paper presents the scheme of zone-based construction sequence analysis, to check the stability of high-rise building under construction. This scheme is applied to the construction sequence analysis for real high-rise building under construction.

  • Stack effects occurred in the stairwell, an important evacuation means of the high-rise building, give a big impact on stairwell pressure difference distribution and it could obstruct evacuation from the building, so should be controlled within proper range. Computer simulation was conducted with CONTAMW2.4 to find the solution of stack effects of the high-rise building. It was able to solve the imbalance pressure difference with a pressurization and a depressurization supplied by fans on higher and lower parts of the stairwell.

  • Frank Lloyd Wright and Mies van der Rohe are two of the most influential architects in modern architecture. In spite of the different values in their architectural lives, the design of high-rise building had been a continuous matter of primary concern for them. The purpose of this study is to compare the architectural characteristics of the two master architects in terms of building form, structure, function, and envelop skin. glass. Both of them shared with the principle of organic architecture even in the design of high-rise buildings. However, the specific approaches to realize it in high-rise buildings are significantly different. Although they emphasized the integration of building form and structure, Wright regarded the reinforced concrete structure as an organic form-giver, while Mies introduced the steel skeleton structure only as an efficient and flexible building frame. As primary finishing materials for high-rise buildings, glass was used for functional purpose by Wright, but for visual purpose by Mies.

  • In recent years, the fire risk in the aged housing facilities in high-rise building has been closing up due to the fire in the Grenfell Tower. In the case of these high-rise residential facilities, fire cases of residential facilities such as Uijeongbu Apartment Fire The fire hazard has been reexamined mainly. Especially, the fire of these residential facilities is very closely related to the window, so measures are needed. On the other hand, in Korea, there is almost no fire safety measures against these openings. Therefore, this study suggests improvement measures by comparison with advanced countries based on fire safety measures for domestic windows.
