Abstract
Deep beam or transfer girder is used for architectural purposes when a lower column on the exterior facade is removed. In this case, sometimes the full depth of the floor-to-floor height is used to transfer the high axial forces of columns above to the supporting columns below To day, in modern buildings , the need for pipes and ducts became necessary to accommodate essential services such as water supply, sewage, air conditioning, electricity, telephone and computer net work, so it is required to install openings in deep beams. These openings often interrupt the load transfer strut in concrete deep beams and cause a sharp decrease in strength and STM is complicated and not easy to predict the failure mechanism. Therefore, it is necessary to study the behavior of deep beam with web openings and study its behavior when adding steel fibers which increase the beam strength. In the first part of this research, a verification study using ANSYS 19 for twelve simple deep beams with dimensions (1800*1100*100) mm was conducted. This research’s parameters include three types of steel fibers, namely end hooked, corrugated round, and corrugated segment. Also, two types of openings sizes (250*250) mm, (350*350) mm, two different openings location, and two different shear span ratios of 1/2 and 1/3. The verification study aims to compare the experimental results with numerical results. It can be concluded that the ultimate strength of reinforced concrete deep beams obtained by ANSYS 19 is in good agreement with experimental results. The second part of this research is the numerical modeling of seventeen continuous deep beams with dimensions (3600,1100,100) mm with the same parameters as simple deep beams to compare simple and continuous deep beams deflection, first crack load, failure load, and mode of failure. Additional parameters were studied, such as different opening sizes of (150*150) mm, (400*400) mm to compare these openings with openings (250*250) mm and (350*350) mm to choose the best opening size. Opening locations at heights (100, 200,425,600) mm were also modeled to choose the best opening location. The presence of reinforcement around openings was also tested to study its impact on failure load. from the numerical analysis, it can be concluded that using steel fiber in deep beams reduced the cracking and improved their ductility and load capacity. End hooked steel fiber increased load failure by 24% in comparison to other fiber types. Beams with small openings size are more ductile in behavior than beams with large openings. Loading at 1/3 shear span saved up to 30% of the structural strength of deep beams. Continuous deep beams increased load failure by about 15% when compared with simple deep beams. The best openings location was found to be at beam center lines which increased the ultimate load capacity by 20.6% and reduced cracks
