Framework for the design and analysis of steel fiber reinforced self-compacting concrete structures

This research focuses on the structural applications of steel fiber reinforced concrete (SFRC). Various fibers are first studied, in order to choose the most suitable type in accordance with the specific application. A steel fiber reinforced self-compacting concrete (SFRSCC) mix, designed for improved performance, was used to cast a 3-m-high, 6-m-long and 0.15-m-thick wall. The experimental tests performed on 380 specimens cut from the wall involved mechanical and non-destructive testing (NDT) procedures. Finally, a relationship between magnetic and mechanical properties was established, in order to predict softening and hardening in the flexural behavior of the composite.

► Real-life SFRC structure (3 m-high, 6 m-long wall) is analyzed. ► An industrial application case study is proposed. ► Merging SFRC and SCC, a suitable fiber orientation is provided. ► A flexural hardening response is obtained with a low fiber dosage. ► Magnetic methods provide valuable prediction of mechanical properties.
