Description
Summary:Arc concrete structures are aesthetic and suitable for buildings with large spans. Within the framework of this research, fiber-reinforced concrete (FRC) dome-shaped structures were studied in a lab, analyzing mechanical performance via strength, deformation, and failure mode. The studied FRC was elaborated with industrial, recycled, and alternative fibers. The mold used for producing the dome specimens was made up of two parts in order to favor extraction. This study considered 21 dome samples reinforced with fibers and one control, with replication for those with atypical behavior. The results show that the load-displacement behavior of dome-shaped elements increases with the incorporation of fibers, which depends on the fiber dose and the material. Moreover, the efficiency analysis proved that specimens with low fiber content (20 and 2 kg/m3) have the best strength-reinforcement relation. The recycled and alternative fibers exhibit good mechanical performance and ductility. The main contribution of this research is a study of the scope and limitations of different types of FRC as the only reinforcement in arched structures.
