Abstract: This paper presents an experimental investigation on circular UHPC-NSC composite columns under concentric loading. The composite columns consisted of a precast spun NSC shell and a UHPC filled core. The spun NSC shell served both as the fire protection layer and a load-bearing element. Different amounts of steel fibers were added to the UHPC core, the amount and arrangement of the lateral reinforcement were also varied in order to investigate the influence of these parameters on the performance of the columns. In order to distinguish the load-bearing portion provided by the NSC shell, UHPC columns with the same geometry, material properties and ratio of lateral reinforcement as the corresponding UHPC core were tested and compared to the composite columns. Observations from the test program were discussed, providing preliminary information for the consideration of the application of this innovative structure.
