This research presents an analytical study to verify the experimental study of new models for reinforcing deep beams with different shear openings, in addition to proposing a formula for calculating the shear capacity of such beams.
The results of the analytical study demonstrated the efficiency of the proposed nonlinear finite element (NLFE) model by close matching the carrying capacity of the tested beams and their comparative analyzed by the ABAQUS program.
The analytical program included representing a 14-specimens study with two different concrete strength and three different sizes of shear openings.
The comparison revealed the accuracy of the analytical model in the representation of solid deep beams and deep beams with shear openings; including predicting the fracture load, the behavior of these beams, in addition to the crack pattern and stresses of the proposed reinforcement configurations.
Using both of ABAQUS program and specifications of the ACI 318-14 (ACI Committee 318, 2014), a parametric study was developed to investigate the relationship between shear strength of deep beams with different sizes of shear openings and shear opening ratio to the total area of shear zone.
Based on this parametric study, a dimensionless equation for calculating the shear strength of deep beams was obtained, which can be utilized in the design of such beams having same shear span-to-depth ratio and opening maximum size of 0.15 relative to shear zone.
