Design and Construction of Steel Diagrid Structures
نویسنده
چکیده
The diagrid structural system has been widely used for recent tall buildings due to the structural efficiency and aesthetic potential provided by the unique geometric configuration of the system. This paper presents a stiffness-based design methodology for determining preliminary member sizes of steel diagrid structures for tall buildings. The methodology is applied to diagrids of various heights and grid geometries to determine the optimal grid configuration of the diagrid structure within a certain height range. Constructability is a serious issue in diagrid structures because the nodes of diagrids are more complicated than those of conventional orthogonal structures. This paper also presents various strategies to improve constructability of diagrids through prefabrication of the nodes.
