  • These days, the super high-rise buildings construction plans are increased in Korea. But the stack effect in the super high-rise building interrupts the smoke control system's operation because of pressure difference, so it is more dangerous than the general building when firing. Therefore it needs to study about the pressure difference in the super high-rise buildings. We research the smoke control influence factor in the super high-rise building. Reflecting the influence factor, the simulation is practiced the case by case.

  • According to the recent trends in the construction business have been actively booming both overseas plant orders and high-rise buildings orders. In addition high-rise building projects have being promoted or is actually under construction in Korea. Frame structure review which is the most consuming period on high-rise building is essential on that project. In this study looks for the currently form system and compares to those large system used in high-rise buildings.

  • The serviceability design of the high-rise building is affected by the wind response vibration such as the acceleration, at this time it is important to calculate the natural frequency correctly. Since the suggestion equation of the natural frequency being used in the design phase is not the regression equation obtained from the vibration measurement of the high-rise building, the verification to use for the serviceability design of the high-rise building is necessary. This thesis conducted an ambient vibration measuring on the high-rise building through the mobile-phone application to calculate the natural frequency and suggested a natural frequency approximate expression following the building's height, and compared with the domestic/foreign standard and the result of the eigen-value analysis.

  • The study aimed to understand the lateral behavior of vierendeel outrigger system in high-rise building. For this goal, a structure analysis and design of 60 stories building was performed by using MIDAS-Gen. And the main factors of this research were the types of outrigger system, the stiffness of outrigger and the location of outrigger system. Based on the analysis results, we analyzed and studied the lateral behavior of structure members such as slab, outrigger and exterior columns in vierendeel and general outrigger system. The study results showed that the types and the stiffness of outrigger system had an any influences on lateral behavior in vierendeel outrigger system of tall building. Also the results of analysis research can be very useful in getting the significant engineering materials for the structural design of vierendeel outrigger system in high-rise building.

  • It is usual to evaluate the performance of the cool roof by measuring in-site rooftop temperature using thermal infra-red camera. The principal advantage of rooftop thermal infrared image acquired in oblique vantage point of super high-rise building as a remote sensor is to provide, in a cost-effective manner, area-wide information required for a scattered rooftop target with different colors, utilizing wide view angle and multi-temporal data coverage. This research idea was formulated by incorporating the concept of traditional remote sensing into rooftop temperature monitoring. Correlations between infrared image of super high-rise building and in-situ data were investigated to compare rooftop surface temperature for a total of four different rooftop locations. The results of the correlations analyses indicate that the rooftop surface temperature by the infrared images of super high-rise building alone could be explained yielding $R^2$ values of 0.951. The visible permanent record of the oblique thermal infra-red image was quite useful in better understanding the nature and extent of rooftop color that occurs in sampling points. This thermal infrared image acquired in oblique vantage point of super high-rise made it possible to identify area wide patterns of rooftop temperature change subject to many different colors, which cannot be acquired by traditional in-site field sampling. The infrared image of super high-rise building breaks down the usual concept of field sampling established as a conventional cool roof performance evaluation technique.

  • Recently, many high-rise buildings have been constructed, and are under construction. And a high-rise building with more than 100 floors is under planning. From site logistics management point of view, it is very important to manage vertical transportation of resource (e.g., material, equipment and construction labors) in high-rise building construction. The higher the building is constructed, the more important it is to manage for vertical transportation of it. In case of labors, vertical movement needs longer time in high-rise building construction than in low-rise. This results in low productivity and work efficiency of the construction. Therefore, this study presents a process of a vertical movement plan for labors using discrete-event simulation. And then the process applies to MT 130 project, which is a virtual high-rise building construction project.

  • 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.

  • This research aimed to grasp the optimal location for two-outrigger system in high-rise building by using MIDAS-Gen. In this study, the main variables of structural analysis research were the outrigger location, the outrigger spacing and the stiffness of primary structural members such as outrigger systems, exterior columns connected in outrigger system, shear walls and frames. For the purpose of investigating the optimal position for two-outrigger system in tall building, we compared and examined the lateral displacement in top floor of 80 stories high-rise building. In the results of this analysis research, it is showed that the outrigger location, the outrigger spacing and the stiffness of primary structural members such as outrigger systems, exterior columns connected in outrigger system and shear wall had an impact on the optimal location of two-outrigger system. Furthermore, it is indicated that the study results can provide assistance in getting the structural design data for searching the optimal location of two-outrigger system in tall building.
