| Abstract | ||
| This research aims to investigate how to increase the structural strength of reinforced concrete deep beam with large openings. Two approaches are under consideration; the first is the effect of steel reinforcement bars near the opening edges, and the second is attaching CFRP layers around the opening. The software ANSYS 12.1 is used to handle the nonlinear finite element analysis. The ultimate strength of reinforced concrete deep beam with opening obtained by ANSYS 12.1 show fair agreement with experimental results (despite the high complexity of the problem), with a difference of no more than 21%. The present work concludes that using a circular opening instead of a square one with the same size can save a 19% of structural strength. Also, the introducing of steel bars around the opening increases the strength by up to 48%, while the using of CFRP laminates enhances the strength by an amount of up to 29% for beams considered in the present research. | ||
