| description | This dissertation presents an experimental investigation on the behavior and
ultimate shear strength of reinforced concrete beam. Sixteen reinforced concrete beams
was design and tested to failure. This study consists of two series of beams, which are
conventional steel reinforced beams (BSN) and reinforced concrete beams with Strut and
Tie Model (STM) using StaadPro software and both result were compared in term of
shear strength. The main test variables were shear span-to-depth ratio (2.1 and 2.9),
percent of longitudinal reinforcement ratio (tension) steel and GFRP (0.6% and 0.9%),
and shear reinforcement ratio (1.5% and 0.6%). The test results revealed that the mode of
failure for all beam is flexural with shear reinforcement characteristics and longitudinal
reinforcement ratio play a critical role in controlling the mode of failure. The
experimental approved that the spacing between shear cracks for the specimens with
larger shear span to depth ratio is greater than the smaller shear span to depth ratio and
while the shear span to depth ratio (a/d) decreases, the shear strength increase. For
longitudinal reinforcement ratio it can be inferred that the higher longitudinal
reinforcement ratio brings the smaller diagonal crack. Also, greater stirrup spacing leads
to the greater diagonal crack, confirming that there is a significant influence of the stirrup
spacing on the spacing between shear cracks. The reason for this behavior is the
decreasing effective concrete area, in which shear crack width is controlled by the stirrup,
and hence the increasing bond effect between the stirrup and the surrounding concrete. |
