| dc.description.abstract | Major parameters that have an influence on the shear strength of beams without shear reinforcements identified by many researchers are shear span to depth ratio (a/d), tensile strength of concrete (ft), longitudinal reinforcement ratio (ρ), size of beam and presence of axial force. Effects of load distribution and tapered/variable depth of beam has not given great concern in many studies as well as in building design codes. Results of experimental tests on twelve shear critical beam specimens were presented to study whether the shear strength of beam is affected by type of load distribution as well as tapered/variable depth. The specimens are comprised of six types of beam namely the PC(prismatic beam subjected to central concentrated), HUC(haunched up beam subjected to central concentrated load), HDC(haunched down beam subjected to central concentrated load), PU(prismatic beam subjected to two point load), HUU(haunched up beam subjected to two point load) and HDU(haunched down beam subjected to two point load). Two types of load distribution have been taken into consideration; the former three types of beams are subjected to central concentrated load and the later three types of beam are subjected to two-point loads. The varied/tapered shape under consideration is haunched beam. Two types of haunched beams are studied; the haunched up beam and the haunched down beam. Each type of beam is casted and tested twice for the perfection of the study. All specimens have the same size h (200 mm), same shear span to depth ratio a/d (2.75) and reinforcement ratio. The study showed that type of loading has significant effect on the shear resistance of haunched beams. The type of haunches also has a significant effect on shear resistance. | en_US |
