Abstract

Abstract

A total of 6 concrete-filled circular steel tubular columns were tested under eccentric load of unequal end-moment.The primary parameters in the tests were end-moment ratio and max eccentricity.The results show that all the specimens were destroyed due to the instability ultimately,end-moment ratio has important effect on the failure modes of the specimens;the greater the end-moment ratio and the eccentricity ratio,the smaller the rigidity and the bearing capacity.On this basis,the behavior of concrete-filled circular steel tubular columns under eccentric loading of unequal end-moments is analyzed by finite element method.The calculated results agree well with the experimental results.
