Fibre reinforced concrete, deep beams, numerical simulationAbstract
In this work we have studied the shear capacity of deep beams reinforced with a combination of steel and polypropylene fibers as a partial replacement for conventional shear reinforcement. To this end, a three-point flexural test was simulated using a three-dimensional model using ABAQUS© software.The HFRH was modeled considering polypropylene fiber concrete as a homogeneous material with equivalent properties on the one hand, and steel fibers as discrete elements distributed throughout the concrete volume. This study was complemented with a parametric study considering fiber orientation as a variable and an analysis of images obtained by computed tomography to evaluate the actual distribution and orientation of these fibers in the VGA. Finally, the numerical results are compared with the experimental data obtained by the authors.
