Hybrid FRP–concrete–steel tubular columns: Concept and behavior

Hybrid FRP–concrete–steel tubular columns: Concept and behaviorAbstractHybrid FRP–concrete–steel double-skin tubular columns are a new form of hybrid columns recently proposed by the first author. Thecolumn consists of an outer tube made of fiber reinforced polymer (FRP) and an inner tube made of steel, with the space between filledwith concrete. In this new hybrid column, the three constituent materials are optimally combined to achieve several advantages not availablewith existing columns. In this paper, the rationale for the new column form together with its expected advantages is first explained.A series of axial compression tests on stub columns are then presented to demonstrate some of the expected advantages. These test resultsconfirm that the…
