摘要：

The eccentric compression thin-walled shuttle cylinders structure is introduced, and elastic eigenvalue buckling of this kind of column with circumferential cracks is numerically simulated by the finite element method (FEM). Besides, based on the numerical results, ultimate load-carrying capacity analysis of eccentric compression thin-walled shuttle cylinders structure with cracks was studied in which geometric nonlinearity is included. The influences of some parameters, including the crack length, eccentricity, slenderness ratio and tapering ratio of thin-walled shuttle cylinders structure, have been taken into consideration. The results show that the ultimate load carrying capacity and the stability behavior can be improved by increasing the tapering ratio or decreasing slenderness ratio, eccentricity and crack length. And they also show that the eccentricity has a relationship with the influence of the crack length on stability behavior, that is, the ultimate load-carrying capacity is improved by decreasing the crack length only when the eccentricity is less than a certain value. Otherwise, when an eccentricity is larger than a certain value the crack length will have no effect on the ultimate load -carrying capacity of structure.
