Evaluating the Central Core of High-rise Shear Wall Structure for Lateral Displacement Control
초록
영어
In general, the shear wall with moment frame system, the shear wall with outrigger system, the tubular system, the mega column system and the cross wall system are adopted as lateral resisting system to high-rise buildings. And a common factor of these systems that resist from lateral loads is the shear wall in the core. Determining the appropriate size of the core is a key factor of designing the lateral resisting system and if the central core is relatively strong to the lateral displacement, restrictions on the grid and facade plan would decrease because requirement of other elements would be reduced. In this paper, the size of cores that a major factor of high-rise building system is analyzed. Changing the slenderness ratio from 2 to 8, structually needed size and areal ratio of the core is estimated from the basic model which has shear wall-moment frame with central core. Additionally relationships with the thickness of walls and differences due to changed rigidity of moment frame around the core are investigated in this study. Also, the difference is analyzed by comparing with the shear wall with outrigger system which is generally adopted as lateral resisting system.
