Abstract

This research deals, The characteristics of mechanics and behavior of the tube structural systems, It has been investigated and considered conventional theory and case models, It has shown the suitability, The best location, And optimal shape of the unit module system, Considered variables materials of stiffness increase and decrease in hybrid tube structural systems this study carried out adapting analysis of statistical concepts. In a concrete way, This study exams the effect of reducing horizontal displacement and the shear lag phenomenon, Also, The purpose of this study is to utilize the basic data on the design and study of future high-rise hybrid structural system using this research. As a result, The framed- tube structural system does not effectively cope with horizontal behavior of high-rise buildings, The results of using varying material tested resistance factors and lateral loads in hybrid tube structural system, When each material is compared Bracing material is identified as a key factor in lateral behavior. In a ratio of material quantity framed-tube structural system, The level of sensitivity affecting the horizontal displacement is greater then the beam's column, In case of braced tube structural system, Braced appeared to be most sensitive in comparison of material quantity ratio in columns and beams.

본 연구에서는 튜브 구조시스템의 역학적 특징과 거동에 대한 이론과 모델 연구 등을 고찰하고, 단위 모듈 시스템의 적정성, 최적 위치. 최적 형태를 파악하고, 각 부재의 강성증감에 따른 부재 변수를 고려한 복합 튜브 구조시스템을 통계학적인 개념을 도입한 민감도 방법에 의한 해석을 수행하였다. 구체적인 방법에서 복합 튜브 구조시스템의 전단지연 현상과 횡적 거동에 대한 특성을 비교 고찰하였고, 또한 그 결과 치를 이용하여 향후 있을 초고층 복합 구조시스템의 설계와 실무에 대한 기초 자료를 제시하는데 연구의 목표를 두었다. 연구 결과로는 골조튜브 구조시스템만으로는 초고층 건물의 횡적 거동에는 효과적으로 대치하지 못하므로, 복합 튜브 구조시스템을 구성하여 횡하중 저항요소로 구성부재를 다양하게 변화시켜 검토한 결과, 각 부재 물량대비 가새 부재가 가장 큰 횡적 거동에 대한 영향 요소로 파악되었다. 골조 튜브구조는 물량대비 보가 기둥보다 횡변위 영향에 미치는 민감도의 정도가 크게 나타났고, 가새 튜브구조시스템의 경우는 가새가 물량대비 기둥 및 보와 비교하면 가장 민감한 것으로 나타났다.
