Analysis of Concrete-Filled Steel Tubular Beam-Columns
The elastic-plastic behavior of pin-ended, concrete-filled steel tubular columns, loaded either symmetrically or unsymmetrically about either of the two axes is studied using the Column Curvature Curve method. Two types of cross section are considered: circular shapes and square shapes. Three types of stress-strain relationship for concrete are studied: uniaxial state of stress; triaxial state of stress, the effect being assumed to increase the ductility only; not the strength; triaxial state of stress, the effect being assumed to increase both the ductility and strength. Using the corresponding stress-strain curves for concrete, interaction curves relating axial force, end moment, and slenderness ratio are presented for the maximum load carrying capacity of the beam-columns. The results obtained are compared with those from tests reported elsewhere, and good agreement is observed. (Author)
