Summary High‐rise buildings are extensively built in China, and the structure of these buildings is composed of different types of conventional system of which framed structures are more commonly employed. A new cassette structure with advantageous performance properties is proposed. Static and dynamic numerical simulations were applied to investigate the characteristics of this new structure. First, the components and other details are presented. A comparative analysis was conducted between the cassette structure and traditional structures using eight finite models with fiber elements in three different heights. A static pushover analysis and an incremental dynamic analysis were conducted based on 18 near‐ground motion records recommended by the Federal Emergency Management Agency. The seismic characteristics, deformation curve, interstory drift, roof displacement, and fragility curve are investigated. Based on the analysis of the models with three different heights and the variety of seismic records, the economic advantage and application of cassette structures for building industrialization are also discussed.

“…The 83‐story structure has a CFST tubular structure, which starts with hexagrids in the bottom and changes to diagrids from mid‐height to the top of the structure . Montuori et al studied 90‐story hexagrid and diagrid structures, designed to resemble the Sino Steel International Plaza under construction in China (Figure ), with diagonal angle in the range of 31° to 70° and concluded that hexagrids have a smaller lateral stiffness than diagrids.…”

Summary In recent years, diagrid structures have received increasing attention among both designers and researchers of tall buildings for creating one‐of‐a‐kind signature structures. This paper presents a state‐of‐the‐art review of diagrid structures. First, various diagrid configurations, main factors affecting their behaviors, and related design parameters and approaches are discussed. Then, diagrid applications for free‐form steel and concrete structures are introduced showing the diagrid applicability for complex structures followed by recent advances in structural design of diagrid connections, diagrid nonlinear behavior, and structural control of diagrids. Recent studies about a new variation of tubular and diagrid systems, hexagrids, are discussed briefly. Finally, the diagrid potential in design of sustainable buildings is delineated.

“…Further, a generalization of the concept of structural pattern, or grid, in the tube configuration for tall buildings has been proposed, and a general approach for modeling, analyzing and designing the relevant structural system has been developed for both regular and non regular grids, i.e. diagrid, hexagrid and Voronoi grid [21,22].…”

Structural configurations best addressing the traditional requirements of strength and stiffness for tall buildings are the ones employing the tube concept, whose efficiency, however, is strictly related to the involved shear-resisting mechanism. In this perspective, diagrid structures -the latest mutation of tube structures -show an extraordinary efficiency, related to the adopted geometrical pattern: thanks to the triangle tessellation of the façades, internal axial forces are largely prevalent in the structural members, thus shear lag effects and racking deformations are minimized. Being also adaptable to whatever surface, diagrid is becoming the most used structural solution for tall buildings of complex form. In this paper some specific design issues for diagrid structures are identified, namely: the relative importance of strength and stiffness design criteria, as well as to the need of secondary bracing systems for counteracting the inter-module flexibility effects. Simplified procedure for dealing with such issues are proposed and design implications are discussed.
