FINITE ELEMENT STUDIES OF PRE-CRACKED REINFORCED CONCRETE (RC) BEAMS WITH OPENINGS STRENGTHENED BY STEEL PLATE
element package ANSYS14.5. To ensure that the elements, convergence criteria, and material properties are adequate
to model the behavior of the RC beam and to ensure that the simulation process is correct, the FE ANSYS was calibrated
with published experimental data. The effect of pre-damage level and loading mechanism were considered as main
parameters. Furthermore, birth and death technique was used to model the cracks before strengthening stage. In this
technique, loading was first applied till the objective cracking, followed by steel plate application, and then the load
was continued to failure. The result showed that pre-damage levels and the steel plate strengthening have a great effect
on the failure mode and ultimate load of RC beam. In addition, the results showed good agreement with those obtained
from published experimental tests. Based on FE using ANSYS an ACI guideline, an analytical equation for predicting
the shear capacity of RC beams with openings strengthened by steel plate under sustained load was then proposed.
