Abstract
The originality of form is one of the new trends that can be identified in the current design of tall buildings. In this design trend, the so-called diagrid structures, which represent the latest mutation of tubular structures, play a major role due to their inherent aesthetic quality, structural efficiency and geometrical versatility. In this paper an overview on application of such typology to high-rise building is carried out; in particular, in the first part of the paper, the peculiarities of diagrid systems are described, focusing attention on the structural behaviour under gravity and lateral load and reviewing strength-based and stiffness-based design criteria. In the second part of the paper, a comparative analysis of the structural performance of some recent diagrid tall buildings, characterized by different number of stories and different geometries, is carried out, namely the Swiss Re Building in London, the Hearst Headquarters in New York and the West Tower in Guangzhou.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
