Thin-walled elements, thanks to their good properties are more often used in structural applications, particularly in aircraft or building industry. This kind structures are often perforated especially for weight reduction and to ease servicing and maintenance operations, e.g. in aircraft wing ribs. What is more, this type of elements, due to its dimension, is susceptible on buckling phenomena, and this susceptible increases with the perforation. This work present the results of numerical analysis of the composite beam subjected to a compressive load. Paper focus on the buckling behaviour of profile with specific types of cut-outs. Three parameters like: holes shape, spacing ratio S/
