چکیده انگلیسی
This paper presents experimental results on the torsional behavior of ultra-high performance concrete (UHPC) beams. Thirteen beam specimens with 300Â ÃÂ 300-mm cross section were cast from UHPC with the compressive strengths greater than 150Â MPa. The experimental parameters were the specimens' volume fraction of steel fibers, transverse reinforcement ratio, and longitudinal reinforcement ratio. The test results indicated that the beams' initial cracking and ultimate torsional strength increased as the volume fraction of steel fibers increased. The ultimate torsional strength and torsional stiffness after initial cracking increased as the stirrup ratios increased, and ultimate torsional strength increased as the longitudinal rebar ratios increased. The effect of the quantity of transverse and longitudinal reinforcement on the angle of the diagonal compressive stresses was investigated. The results of this study provided valuable data that could be used in future studies to develop computational models of the torsional behavior of UHPC beams and predict their ultimate strength.
