Title: Elasto-Plastic Analysis of a Core Subjected to Torsion
Author(s): J. Schwaighofer and W. N. Ho
Publication: Special Publication
Appears on pages(s): 497-514

Abstract:The equivalent frame method is employed in the elasto-plastic analysis of a perforated core structure which is subjected to uniformly distributed torque over the height of the core. In a step by step approach the sequence of crack formation, and the onset of yielding of the tension steel in the coupling elements and the shear walls is given.
