What is Torsional Behavior of Tapered CFDST Columns about?

This paper investigates the torsional behavior of tapered concrete-filled double-skin steel tubular columns with large hollow ratios (LHR-CFDSTs), which are beneficial for structures subjected to lateral loads. The study includes numerical analyses to understand the torsional mechanisms and proposes a refined prediction method for torsional capacity, demonstrating good accuracy for columns with tapered angles over 1.50°. Key findings reveal significant torsional deformation and stress concentration within t
