Loading tests were conducted on three steel-tubed reinforced ultra-high-strength concrete columns to study the effect of the amount and strength of transverse reinforcement on their flexural behavior using these three specimens and four previously tested specimens by authors. Test results showed that the shear reinforcement had a significant influence on the ultimate deformation. A motion capture system was used to investigate the stress condition of the concrete. A fiber-based analysis was also carried out to find the proper stress-strain relation for concrete to simulate the moment-curvature relations.
