Abstract

This paper presents an experimental and numerical study of concrete-filled steel tubular stub columns strengthened with fibre reinforced polymer (FRP) wraps under axial compression. Twenty specimens were tested to investigate the effects of steel tube shape, number of FRP layers and steel ratio on the performance of the composite columns. The test results indicated that the FRP jackets could enhance the load-bearing capacity for the circular columns effectively, whereas the enhancement was less significant for square columns. Nonlinear analysis is performed using ABAQUS software, and reasonable agreement is achieved between the predicted and test results. The mechanisms of FRP and steel tube confinement on the column behaviour are then investigated using this modelling.
