Abstract
This research presents an experimental analytical investigation in
the Dowel Action Effect on the Shear Capacity of Reinforced
Lightweight Concrete Beams. LWC was obtained through the use of
polystyrene foam as a partial aggregate’s replacement to reduce the
concrete dry unit weight to 1.80 t\m3 . The experimental investigation
consisted of two phases; namely, the LWC mechanical properties and
shear behavior of reinforced LWC beams. The mechanical properties
incorporated the compressive and tensile strengths of lightweight
concrete. In the second phase, a total of eight medium scale reinforced
foam particles LWC beams were casted and tested. Three main
parameters were investigated in the study, namely; the longitudinal
reinforcement ratio, concrete strength, amount of stirrups.
To fulfill the previously mentioned objectives, this research was divided
into the following chapters
