This innovative material, resistant to corrosion, allows the concrete cover to be reduced to a minimum, enabling the construction of very filigree components and members. Against this background, the stability behavior is a theme of growing importance for the design of such structures. Moment-normal force interaction diagrams can help to assess the failure mode of slender compression members. Hence, an analytical failure envelope for carbon-reinforced concrete under combined bending and longitudinal force is derived, using an adapted, linear-elastic material model for the non-metallic reinforcement. Experimental investigations on carbon-reinforced concrete components with different slenderness ratios under simultaneous axial and flexural loads unveil insights into load-bearing and deformation behavior. This research contributes to the development of sustainable and resource-efficient concrete structures, emphasizing the significance of stability and slenderness ratios in design considerations.enBucklingCarbon-reinforced concreteFailure envelopeMoment-normal force interactionTechnology::620: Engineering::620.1: Engineering Mechanics and Materials ScienceTechnology::620: Engineering::620.1: Engineering Mechanics and Materials Science::620.11: Engineering MaterialsTechnology::600: TechnologyConference Paper10.1007/978-3-031-70145-0_83Conference Paper
