摘要：

This paper presents the results of a study investigating the eccentric compression loading of thin-walled composite profiles with Z, channel and top-hat sections. The buckling, post-buckling and limit state of the profiles are investigated. The primary objective of the study was to determine the effect of load eccentricity and profile section type on the stability and load-carrying capacity of the profiles. The thin-walled profiles made of CFRP by the autoclave technique were subjected to static compression over the full range of loading until final failure. At the same time, the compressed profiles were examined by nonlinear numerical analysis with the finite element method using the commercial simulation software ABAQUS (R). Damage initiation in the composite material was analysed using the Hashin criteria and a progressive damage model. Numerical models were validated by experimental tests. Obtained numerical and experimental results show a high agreement.
