  • 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.

  • Recently, For the most efficient use of spaceis, high-rise buildings tend to increase. So it is with Korea, too. Besides, today high-rise buildings grows due to fire damage to life and property at large. In this study, Through analysis of domestic and foreign fire case and listen to the high-rise building fire managers, tenants, professionals advice, when the fire from the high-rise building, effective fire suppression tactics should we wish to research ways. In addition, we have used the car gondola was installed outside the fire suppression methods in studying. So that fire-fighting is a fire place can be reached quickly, many casualties and property damage, will be reduced.

  • The objective of this study is to analyze the space usage and user evaluation of community facility in High rise Mixed-use Apartment. This study was conducted case study and questionnaire survey. Four High rise Mixed-use Apartments built since 2000 were chosen for case study and 166 residents were collected for questionnaire survey. The frequency, percentage, mean, t-test and F-test were executed through SPSS for Win 12.0 statistics package program. The types of community facilities of High rise Mixed-use Apartments were consisted of sports, child care/study, information sharing, leisure/cultural facilities. The usage percentage of community facilities increased since the residents have moved to their current residence of High rise Mixed-use Apartments from their previous residence. The most satisfactory facility was sports facilities. The satisfaction of community facilities showed high in general. The satisfaction of community facilities was significant with gender and age.

  • Contrast a general building high rise buildings itself has a kind of risk. In this study, the risk of a number of high rise buildings have fire fighting safety management of the particular risks associated with looking for ways to minimize focused. Issues include self fire protection. disaster management, building code and fire code of the mismatch, such as fire protection facilities aspects are explained in terms of three kinds, and for it to take steps in the direction suggested an alternative for high rise buildings. Although differences of opinion between departments will not be easy to fire fighting and building codes regarding conflicts of codes above all require immediate resolution, and high rise buildings to create a standard for effective risk management manual countermeasures will also be ensured.

  • In the late of 1990s, a super-high-rise residential started with the concept corresponding to a natural view, as the habitants' desire for spaciousness worked on an initiative factor. The appearance of the new style of residential form was encouraged and habitants' items desired were increased by the security of spaciousness for view. The purpose of this study is to understand spatial trans orientation through the plan type focusing the recent case study of super-high-rise and to interpretate spatial changes of residential space following it. For the case study, 20 apartments(or apartment complex) were selected from more than 25 storied super-high -rise located in Seoul and the metropolitan area. On the other hand, the objective facts about super-high-rise were cited in the results of the established studies and the selected cases were extracted from a catalogue and internet

Study on the Eco-friendly Design Methods of the High-rise Residential-Commercial Building -Based on a work of Ken yeang, Bishopsgate Towers- (초고층 주상복합건축물의 친환경적 디자인 방법에 대한 연구 -켄 양의 Bishopsgate Towers를 중심으로-)

  • In the modern city in which the high-density and complex land use is needed, high-rise residential-commercial buildings appeared as a scheme to arrange a metropolitan residence with multiple high-techs and to induce activation of the city with leading the settled population to flow into the city. And the need of the times is to actively apply the eco-friendly notion to the architecture. In this study, the works of Ken Yeang who is regarded as an eco-friendly architect to make high-rise residential-commercial buildings ecological should be focused on with analyses of eco-friendly characteristics in inside, intersection between inside and outside, and outside of his works. The result o the study would be the suggestion to design eco-friendly high-rise buildings which make the city rise in quality.

  • A triaxial Blumlein pulse forming line has been designed to generate a pulse whose voltage is ~300 kV, pulse duration is ~5 ns, and rise time is ~500 ps. It turns out, however, that the rise time of the pulse becomes much longer than 500 ps due to parasitic inductances and capacitances existing inside the system. A peaking switch has been developed to shorten the rise time of the pulse from Blumlein pulse forming line. In the peaking switch, a wedge-shaped dielectric material (MC 901 nylon) is employed to surround the electrode on the antenna side. This shape inhibits an abrupt change of the output impedance, thereby minimizing the reflection of the output pulse. Experimental results show that the peaking switch is capable of improving the rise time of the pulse at a level of 500 ps.

  • As building heights increase, so do these challenges in Korea. High-rise buildings present a variety of challenges to fire safety and protection. The fire protection technology in our country is still on a weak situation which is mainly due to the lack of concerns by the government, companies and citizen. This paper provides general guidance regarding fire-related property protection system for high-rise building performance based design. The importance of high-rise building in of the number of occupants, the value of property, and the a catastrophic loss would have on the community all warrant an increased level of protection and life safety. Because, We have to prepare a new spacial code and standard guidance for fire protection at the stage of the high-rise building design.

  • As high-rise buildings become more and more slender and flexible, the wind effect has become a major concern to modern buildings. At present, wind engineering for high-rise buildings mainly focuses on the following four issues: wind excitation and response, aerodynamic damping, aerodynamic modifications and proximity effect. Taking these four issues of concern in high-rise buildings as the mainline, this paper summarizes the development history and current research progress of wind engineering for high-rise buildings. Some critical previous work and remarks are listed at the end of each chapter. From the future perspective, the CFD is still the most promising technique for structural wind engineering. The wind load inversion and the introduction of machine learning are two research directions worth exploring.
