Basements of ordinary buildings are usually made of conventionally reinforced concrete. Reinforcement is crucial for both load-bearing capacity and serviceability. Applying Steel Fiber Reinforced Concrete (SFRC) in basement design without conventional reinforcement represents a significant advancement for such structures. This research investigates the potential of SFRC as a viable alternative for floor areas up to 20 × 20 m, aiming to reduce construction costs and simplify the building process. In these investigations, the foundation slab and the basement walls are considered as structural elements reinforced only with steel fibers, eliminating the need for traditional steel reinforcement and improving resource and construction efficiency. Key aspects include ensuring compliance with crack width requirements and optimizing the basement’s geometrical dimensions to maintain structural integrity. This detailed study was conducted at the Institute of Structural Concrete at Graz University of Technology in cooperation with the company “ArcelorMittal”. The focus is on the structural response of SFRC in basement constructions, regarding imposed deformations during hydration of concrete and the soil structure interaction under service loads as well as a verification of the ultimate limit state. Extensive parameter studies using nonlinear finite element analysis were performed to evaluate force distribution due to external loads and the crack propagation in the foundation slab and the walls made of SFRC. The results suggest that SFRC is a promising material for future construction projects, offering potential for efficient building solutions.
