| Abstract | ||
| Ten of reactive powder concrete (RPC) T- beams, 1300 mm length, 100 mm web width and 160 height, with different type of section (hollow and Solid) tested under pure torsion to study the significant effect of concrete core and steel fiber percentage on crack and ultimate torsional capacity. An increase of 191% and 64% for solid section and 174% and 59% in for hollow section respectively was achieved when increasing steel fibers percentage to concrete mix from zero to 2%, as longitudinal and transverse reinforcement ratios were kept constant (ρl=0.01, ρs=0.02). The result indicate that the concrete core has no significant effect on the ultimate torsional strength and beam elongation. | ||
