Circular Inclined Concrete-Filled Steel Tubular Stub Columns subjected to Axial Compression

摘要

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.
