The main objective of the current paper is to investigate the effects of the ratio of steel fibers on the structural behavior of reinforced concrete hemispherical domes. Three reinforced concrete domes were experimentally implemented, two of them made fully of reactive powder concrete and the last one made of ferrocement concrete. All specimens have 800 mm diameter, 400 mm height, and 20 mm thickness, and they are reinforced with welded wire meshes. The experimental program included casting and testing the domes, by applying a single point load at the center of the dome, until the failure happens. The first cracking load, ultimate load, load-deflection curves, and crack pattern for all tested domes were included in this study. In general, the effects of concrete type and the ratio of steel fiber are obviously important on the behavior and ultimate strength of the domes.
