Abstract: Experimental studies characterizing the structural performance of self-compacting concrete (SCC) are limited and this can be identified as one of the barriers to the widespread use and acceptance. The prime focus of this study is to characterize the behavior of bamboo reinforced SCC beams without stirrups. Twelve SCC and vibrated concrete (VC) beams were tested under four-point loading till ultimate failure. The major variables considered were the beam depth and the level of longitudinal reinforcement. Results indicated that the contribution from dowel action of bamboo to ultimate shear strength may be quite significant, and slightly higher in SCC beams than VC beams. The deformation capacities of tested SCC beams are comparatively higher. Shear provisions from four design standards were considered to evaluate their applicability to bamboo-reinforced self-compacting concrete beams without stirrups. From this limited study, estimated shear capacities from the Canadian standard, CSA-A23.3-14, were found to be conservative. Moreover, in order to achieve a conservative design, shear strength results revealed that a simple reduction factor of 2.5 is appropriate, adequate, and must be applied to the documented shear provisions of the standards being considered herein.
