A thin-walled steel tube/bamboo plywood composite hollow column with binding bars (SBCCB) was developed using transverse binding bars to reinforce a thin-walled steel tube and bamboo plywood composite hollow column.
In the current study, geometric dimensions of the hollow column sections were chosen in such a way that they have almost equal local and flexural buckling stress.
Also, a database of almost all RC hollow column tests available worldwide was assembled and used in quantifying the effect of increasing ductility on the column shear strength.
The model was developed based on the test results of this study, as well as other hollow column tests available in literature.
Furthermore, the effects of the concrete strength of the core column and the hollow column as well as the interface on both the loading capacity and deformation of the semi-precast columns are studied through numerical simulations by the commercial finite element program ANSYS.
The segmental hollow column specimen also exhibited ductile behavior under cyclic loading.

Maybe solid columns held up roofs, and hollow columns create the illusion they do.
In total, five hollow columns and ten concrete-filled columns were tested.
Six of the columns had a circular cross section (two solid columns, two hollow columns each having a circular hole, and two hollow columns each having a square hole) and the remainder columns had a square cross section (two solid columns, two hollow columns each having a circular hole, and two hollow columns each having a square hole).
Five 1/4-scale rectangular hollow columns were tested under quasi-static lateral cyclic loading.
It was found that FRP confinement increased hollow RC columns' axial load and ductility capacities; and hollow columns having circular holes had better performance compared to hollow columns having square holes.
