Buckling of circular CFDST slender columns with compliant interfaces - exact solution

Schnabl, Simon (author), Čas, Bojan (author)

The paper presents a new mathematical model and its exact solution for the buckling analysis of circular CFDST slender columns with compliant interfaces between the steel tubes and sandwiched concrete. The exact critical buckling loads are calculated for the first time. The results are compared to the experimental results and good agreement is obtained. A parametric study is also performed to investigate the effects of different parameters on buckling loads. It is shown that buckling loads can be significantly affected by the finite interface compliance.
