An experimental study was performed to examine the effect of section depth on the strength and serviceability of reinforced concrete deep beams. Full-scale tests were conducted on simply supported beams with the following cross sections: 21 x 23 in. (533 x 584 mm), 21 x 42 in. (533 x 1067 mm), and 21 x 75 in. (533 x 1905 mm).

Shear size effect in simply supported RC deep beams
Engineering structures, 2019The shear size effect refers to the phenomenon that the shear strength of reinforced concrete (RC) beams decreases as the beam depth increases. The shear strength of RC deep beams is sensitive to boundary conditions (in this case, load- and support ...

Modeling of shear mechanisms and strength of concrete deep beams reinforced with FRP bars
, 2020With the growing application of concrete structures reinforced with fiber reinforced polymer (FRP) composite materials, it is necessary to develop more rational mechanical models for their load-carrying capacity evaluation.

Using the strut-and-tie approach, this paper examines three aspects of deep beam design, which as yet has not been conclusively dealt with by earlier researchers. Previous test results hare been used to justify the use of the previously mentioned principle in predicting the shear strengths of deep beams that are continuously punctured by web openings ...

The theory used for the design of slender beams has a limited applicability to deep beams, resulting in designs that are generally not conservative. Shear warping of the cross section and a combination of diagonal and flexural tension stresses in the body of a deep beam require that deep beam theory be used for the design of such members.

The multiple Fourier technique is used to compare the stress fields in single span deep beams due to uniform loading at the top edge and at the bottom edge. The method involves the superposition of three stress functions. The first stress function is used to satisfy the boundary conditions on the upper and lower edges of the beam.
