摘要
以核心筒的位置改变,以及斜交网格结构的对角支撑间隔不同为变数,分析斜交网格结构受到水平荷载作用时的水平变位,扭转角,扭转刚性和结构的剪力延迟现象等方面。并通过与其他的结构体系的对比,分析各个结构体系对水平荷载的抵抗性能以及对扭转的抵抗性能。
Steel framed high-rise buildings structural system is used in construction of skyscrapers recently,those skyscrapers are using inclined atypical appearance.Diagrid structures are one of the tube structures system having high resistance to horizontal load and support vertical load and horizontal load efficiently.Those buildings do not need strong core inside and have a aesthetic exterior.That's the one of the reason why structural diagrid system is popular recently.In this study,analysis of how structural diagrid system is reacted to the change of core position and various twist was conducted.The comparison analysis of the control torsion impact according to the horizontal resistance factors was conducted.And this paper reviewed how the gap of diagonal bracing affects torsion of building according to diagrid structure system.It evaluates that each system can control displacement and torsion in how efficiency.And it is used for profitable application in a tall building structural plan.
