Abstract: Diagrid structures have been prevalently used for tall buildings worldwide due to their structural efficiency and aesthetic potential. This paper provides design guidelines for diagrid structures for tall buildings. Optimal grid geometry is discussed for diagrids of various configurations. A stiffness-based design methodology for determining preliminary member sizes for the diagonals is presented. Guidelines are presented for determination of optimal bending and shear deformations depending on grid geometries and height-to-width aspect ratios of diagrid structures.
