Behavior of axially loaded circular stainless steel tube confined concrete stub columns [PDF]

Thin-Walled Structures, 2019
A stainless steel tube confined concrete (SSTCC) stub column is a new form of steel-concrete composite column in which the stainless steel tube without bearing the axial load directly is used to confine the core concrete.
