Recently buildings are constructed in larger and higher scales and becoming more complex. Every country in the world is competing to build high-rise buildings. Korea also has and is constructing high-rise buildings, like the 123story Jamsil Lotte Super Tower. However from small to large scale buildings and on construction sites there still are fire safety accidents that occur continuously. Therefore to improve fire safety plan, examining the actual fire safety management and understanding fire risk analysis Using Fire Modeling through Computer Simulation. Fire safety management plan related fire safety cases were collected an dan analyzed for the study. Also hazard analysis of High rise Buildings under fire compared with existing fire law sand regulations.

Recently, may high-rise buildings have been constructed, and will be constructed so that concerns about high-rise buildings have increased. We need to develop energy saving techniques immediately because the high-rise buildings consume a lot of energy. The most of effective energy saving method is the application of the efficient lighting designs and fixtures. The purpose of this study is to analyze the trend of lighting design, fixture and control system in Korea and it can be used the lighting application guide-line for the high-rise buildings.

The purpose of this research is to analyze the publicity of the private open space of high-rise office buildings in seoul. The contents of this research consist of two main parts. The first part is to classify the personal behavior's characteristics and to investigate the user's satisfaction of the publicity in the private open space through the case study of samples in seoul. The second part is to analyze the correlations between the personal behavior's characteristics and the user's satisfaction of the publicity in the private open space of high-rise office buildings. In conclusion, this research will contribute to establish the planning methods of the private open space of high-rise office buildings and to promote the quality of urban residential environment in Korea.

Research and development on high-rise or large-scale wooden buildings have been actively conducted both domestically and internationally. The trend of high-rise wooden buildings is driven by increasing awareness of environmental issues. To utilize wooden materials in buildings is believed to lead to the reduction of the environmental impact. On the other hand, Japan is one of the most earthquake-prone countries in the world, and many wooden detached houses have been damaged in past major earthquakes. This paper summarizes the issues that arise in the realization of medium- and high-rise wooden buildings in Japan, and introduces the initiatives that have been seen so far.

Using synchronous surface pressures from the wind tunnel test, the three dimensional wind load models of high-rise buildings are established. Furthermore, the internal force responses of symmetric high-rise buildings in along-wind, across-wind and torsional directions are evaluated based on mode acceleration method, which expresses the restoring force as the summation of quasi-static force and inertia force components. Accordingly the calculation methods of equivalent static wind loads, in which the contributions of the higher modes can be considered, of symmetric high-rise buildings in along-wind, across-wind and torsional directions are deduced based on internal forces equivalence. Finally the equivalent static wind loads of an actual symmetric high-rise building are obtained by this method, and compared with the along-wind equivalent static wind loads obtained by China National Standard.

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.

Recently, two unique high rise buildings have been designed and constructed in Korea. The two buildings, which consist of mega braces and mega columns, are 70-story, 105-story high rise buildings. Through two external structural frame systems, it will be analyzed mechanical and structural characteristic mega column and mega brace system in this report. Particularly, the joint has been studied through the analytical method based on the load transfer mechanism at the point where a mega brace and mega column meets.

As the height and flexibility of high-rise buildings increase, the wind loads become more dominant and the combination coefficient of Equivalent Static Wind Loads (ESWLs) should be considered when they are used in the structural design. In the first phase of the study, a brief introduction to the theory on the combination coefficient for high-rise buildings was given and then the time history of wind-induced responses of a 208-meter high-rise building with an elliptical cross-section was presented based on the wind tunnel test results for pressure measurement. The correlation between wind-induced responses was analyzed and the combination coefficients of ESWLs of the high-rise buildings using Turkstra's rule, and Asami's method, were calculated and compared with related design codes, e.g., AIJ-RLB, ASCE 7-10, and China Load Code for structural design. The results of the study showed that the combination coefficients from Asami's method are conservative compared with the other three methods. The results of this paper would be helpful to the wind-resistant design of high-rise buildings with elliptical cross-section.

Openness to outside is one of the most critical advantages for high-rise buildings. However, the effect of openness can be decreased if it is blocked by other high-rise buildings, especially built within the building complex of commercial district. The purpose of this study is to identify the horizontal openness of high-rise residential buildings by comparing 3 different cases of building arrangement type. A new method of evaluation has been introduced on the basis of distance to measure the openness including the matter of securing privacy. As a result of this study, comparative analysis was possible and relatively plentiful results of analysis could be drawn out. Through the process of analysis, this study set the evaluation indicators suitable to the analysis of openness of unit households. Thereby, the results of this study are expected to be used as useful basic data in planning high-rise mixed-use buildings.

This paper describes the possibility of the raft thickness reduction for mega foundations system of super high-rise buildings through a case study on domestic and foreign super high-rise buildings. In case of super high-rise buildings, the size of foundations, especially raft becomes wider and deeper because of heavy upper load. It is difficult to pour concrete of this kind of mega foundation, and cracks by hydration heat could happen. Therefore, there are several ways to reduce the raft thickness of mega foundations. Piled-raft could be the one because moment and shear load that the raft subjects on by soil reaction are lower. The effect of the piled-raft foundation on the raft thickness reduction could be confirmed by comparison of super high-rise buildings with pile, piled-raft and mat foundation. Furthermore, it was showed that the raft thickness could be more reduced by locating piles right under the vertical members of super structures.
