Abstract
- The objectives of this study are to investigate and evaluate the use of the finite element method (FEM) in predicting numerically nonlinear behavior of precast reinforced concrete dapped-end beams (DEBs) and comparing the results with previous experimental tests results and with the building codes design methods for the dapped-ends beams. The analysis will be done using ANSYS 2020 R1. The Design methods are the PCI design handbook method and the method of the strut-and-tie model. The experimental tests done by previous researchers were used to analyze in the ANSYS program. Those researchers used the strut-and-tie model and PCI design approach in their failure loads predictions. The load-deflection curves from the ANSYS model were found to be in good agreement with that of the two experimental data and the failure loads are very close also. By comparing the outcomes of STM and PCI, it was discovered that the strut-and-tie method is the best way to design the D-regions in the dapped-ends beams, because its able to fairly satisfy the dapped-ends beam's details. The PCI design approach, on the other hand, produced less accurate shear capacity values. [ABSTRACT FROM AUTHOR]
