Abstract: In order to find out the mechanics behaviors of the inclined CFST stub columns which are used in some real engineering projects, a series of tests are performed and a total of 6 specimens with circular section were experimented. The main parameters were the inclined angle (0 degree and 9 degree) and with or without infilling concrete. Comparisons between measured sectional strengths and predicted sectional strengths using the existing codes were made. The results show that the circular inclined CFST stub columns behaved in a ductile manner and all the codes were conservative and available for predicting the capacities of the specimens.

Abstract: 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.

Abstract: In recent 10 years, inclined concrete-filled steel tubular (CFST) columns are applied for some real engineering projects in China. And so a total of 10 specimens were experimented to study the behaviors of the rectangular inclined CFST stub columns. The main parameters were the inclined angle (0 degree and 9 degree), the inclined orientation (major axis and minor axis) and with or without infilling concrete. Comparisons with predicted sectional strengths were made using the existing codes. The results clearly show that all the codes were conservative and available for predicting the capacities of the specimens.
