Preliminary Analysis on Inclined Concrete-Filled Steel Tubular Stub Columns with Circular Section under Axial Compression
This paper reports a finite element analysis of the compressive behaviour of circular inclined CFST stub columns. A set of test data were used to verify the FE modeling. Typical curves of vertical load versus longitudinal strain, stress distributions of concrete, interaction of concrete and steel tubes, as well as effects of important parameters that determine failure modes of the composite columns were investigated. The results clearly show that the FE modeling is available for predicting the capacities of the circular inclined specimens.
