A Comparison Between Inclined Stirrup And U-Stirrup BEAM-Finite Element Approach.

Abstract

In this present study, a numerical analysis has been performed to compare the shear resisting capacities between conventional loop stirrup beams and inclined stirrup beams. Resisting the shear force is one of the key features of stirrups. A rarely used and uncommon inclined stirrup setup is analyzed in this study and new findings are compared with loop stirrup results. Two sets of beams (150x300x1960mm) are analyzed to determine the ultimate shear force resisting capacities, displacement, and stress resistance capacities. It was seen that the beam with an inclined stirrup showed ultimate shear resistance up to 187.24 KN compared to the beam with a loop stirrup setup which was 114.24 KN. Displacement was found in the inclined stirrup setup and the loop stirrup setup was 2.38 mm and 4.21 mm. Stress resistance and distribution pattern was also improved on inclined stirrup setup. Flexural and Shear Crack patterns of the beams at the ultimate load are also predicted from numerical analysis. Numerical study has been carried out by using Finite Element Software ABAQUS. Finally, these results were also compared with the theoretical formula available in the literature to justify the numerical analysis.
