ABSTRACT
The research focused on thin-walled composite columns made of CFRP. The test specimens had identical geometric parameters and material properties. The research involved static three-point bending tests and used several interdisciplinary research methods to evaluate the behaviour of the structure. The paper primarily focused on evaluating the load-carrying capacity of the structure and identifying the stages of composite material damage. During the tests, the impact of changing boundary conditions (support spacing) and the method of arranging the specimen in relation to the crossbeam on the load-carrying capacity of the structure was evaluated. This was a novel approach compared to previous research in the subject literature. This paper presents research that aims to highlight the key aspects relating to the effect of support spacing and the method of fixing the test specimens on the operational conditions of the structure. The results obtained were compared in terms of quantity and quality.
