Abstract
A novel composite shell system called FWSCT (FRP-wrapped steel corrugated tube) is composed of steel corrugated tube and fiber reinforced polymer (FRP). A series of experiments have been conducted to investigate the mechanical performance of FWSCT applied to steel-reinforced concrete (SRC) circular columns. This paper introduces the development of FWSCT, and the experimental programs on the FWSCT-jacketed SRC circular columns under uniaxial compression and pure bending. A total of 48 small-size FWSCT-jacketed SRC column cylinders were loaded axially, and the other five large-size circular column specimens were tested under four-point bending. Test parameters include the type of shaped steel, steel tube confinement, and the FWSCTs with various FRP layers and orientations. The experimental results were used to identify the mechanical contribution of various FWSCTs to the column strength and as the database for model development and numerical simulation for FWSCT-jacketed columns. Test results have validated the confinement effect and failure mechanism of the FWSCT applied on SRC columns.
