최근 초고층구조물 및 대공간구조물등에 대한 소방법의 성능설계등이 법제화되어 시행될 예정으로 있으나 화재성상예측등에 대한 기초적인 연구등이 매우 부족한 실정이며 이에따라 성능설계를 실시하기 위한 기반여건이 매우 취약한 조건이다. 특히 강구조건축물의 경우 초고층구조물의 전형적인 구조형식으로서 성능설계에 대한 연구기반이 조속히 필요한 실정이다. 따라서 본고는 전보에 이어 화재하중등과 밀접한 관련이 있는 가연물조사등과 더불어 이에 대한 이웃 일본건축학회의 강구조건축에 대한 성능적 내화설계방법론중 하중편을 조사하여 향후 국내의 화재하중선정을 위한 기초자료로 사용될수 있도록 하였다.

The increase of hish-rise residential-commercial buildings is required to cut down a term of works and the cost of construction. Reinforced concrete structures and steel framed reinforcement concrete that are commonly used have the difficulty in reducing them. Therefore, the purpose of this study is to propose a new precast concrete complex system and to analyze its economical feasibility. The economic analysis is performed through comparing the cost of a high-rise reinforced building that was already constructed with that of the new proposed precast concrete system, which is limited to structural frame work of typical floors. This study shows that the proposed precast concrete complex system is economical. Further research should be directed at including the influence of a term of works.

This study was performed for application of Structural Health Monitoring system of Jamsil Lotte World Tower. Axial stresses of mega column and core wall are measured in the past 29 months for axial stress monitoring and evaluating predicted self weight. We use the midas gen program(FEM analysis program) with construction stage analysis mode to predict axial stress. 8 mega column axial stressmeters are installed at 21st floor and 4 core wall stressmeters are installed at 38th floor. Measurement data was obtained without creep and shrinkage effect.

The megastructure combined with the modular concept is an effcient structural system adequate for ultra-tail buildings for the future. An ingeneous structural control system can be developed by separating the internal subframe in one or many modules from the external megaframe, thus taking advantage of the effect of tuned mass dampers without adding any aditional mass. This so called mega-subcontrol system is generally modeled by a 20DF system for parametric study and for finding optimal values of the parameters. In this study the equation of motion for the system is obtained frist and the preconditions for the simplified modeling are investigated. Finally the optimal value for the subsreucture strffness is fomputed with given mass and damping ratios and transfer functions for responses are abtained for white noise ground exitation to verify the effectiveness of the mega-subcontrol system.
