| The research focused on thin-walled composite columns made of carbon fiber reinforced polymer (CFRP). The test specimens were thin-walled, rectangular composite columns. The test specimens had identical geometric parameters and material properties. The research involved static three-point bending tests and used universal testing machine and non-destructive 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. The study analysed two main aspects: the effect of support spacing and specimen positioning relative to the supports on the structure's behaviour, particularly in terms of damage. Both of these aspects are presented separately in the paper, with the impact of each demonstrated in the results. Considering the positioning method of specimens relative to the supports, the specimens exhibited an average load-carrying capacity that was 1.13 times higher when the load was applied to the narrower surfaces of the specimens than to the wider surfaces. In addition, it was found that the specimens demonstrated the highest maximum load when the support spacing was smallest (100 mm). For samples where the load was applied over a wider surface area, the load was 1.21 times higher for a support spacing of 100 mm than for 150 mm. A similar situation occurred for samples where the load was applied over a narrower surface, with a ratio of 1.15 for an analogous support spacing. |
