Description
Summary:An approximate method is presented for the analysis of asymmetrical core structures in tall buildings subjected to torsion. The folded plate approach is used, in which the core is considered as an assembly of vertical panels rigidly connected along their edges, the influence of openings in any of the panels being included by the use of the continuum technique. A closed form of solution is achieved by assuming that the core twists about a fixed vertical axis of rotation. Solutions are given for a wide range of cross-sectional forms, including multi-cell and multi-bay structures, subjected to standard load systems.
