Numerical modelling of concrete-filled steel tubular short columns under axial compression
(Building Materials and Structures, 2023)
The paper presents three-dimensional numerical models of short concrete-filled
steel tubular circular columns that can successfully describe the column behaviour
under axial compression. Several of the most commonly used ...
