Effect of Different Reinforcement Configurations on the Behavior of RC Wide Beams
Abstract
In this paper, different models of reinforced concrete wide shallow beams were studied numerically via ANSYS platform and a parametric study was conducted. Nine beams were loaded with lateral load and only one beam was loaded vertically with lateral loads. It is worth mentioning that some of the most important parameters are: web reinforcement ratio, lower reinforcement ratio, and upper reinforcement ratio. In addition, it was found that the different parameters: lower reinforcement ratio (1.5%,1%,0.7%,0.3%) of cross section area, upper reinforcement ratio (0.8,0.6,0.5,0.4) of the tensile reinforcement, and web reinforcement ratio (0.13 %,0.067%) have significant effects on ductility, dissipation, toughness, stiffness, over strength, stress, and strain. The results reveal that the studied parameter impacts all these properties. For instance, the beam (1%Ac bottom,0.6As upper, 10 str/meter) was the most suitable element for ductility, toughness, dissipation, and Shear. Furthermore, the least ductility was found in the wide beam (0.3%Ac bottom,0.4As upper, 5 str/meter).
