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.

Journal of Structural Engineering, 1983
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.

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).

Tests were carried out on deep beams of steel and concrete. The distribution of the horizontal stresses for each test has been plotted and the expected magnitude at different points on a section were calculated. A theory based on the theory of elasticity, both for steel and concrete, and ultimate load for the concrete has been developed.

Beaming Daylight Into Deep Rooms
Batiment International, Building Research and Practice, 1985Among the options of reducing energy consumption by artificial lighting in buildings is the effective use of natural lighting. By using direct-beam radiation from the sun, deeper light penetration and higher illuminance levels can be achieved in buildings that are predominantly used in the daytime.

Comparative analysis of deep beams
Computers & Structures, 1992Abstract The characteristic behaviour and mechanism of load transfer of deep beams are studied employing the eight-noded isoparametric finite element considering the effect of reinforcements. The authors' generalized formulation is specialized to ignore the reinforcement to apply in a problem solved earlier by other investigators with a view to ...

Results of tests on 52 deep reinforced concrete beams under two equal symmetrically placed point loads are reported. The investigation's objectives were to study the effect of vertical and horizontal web reinforcement and shear span-to-effective depth ratio on inclined cracking shear, ultimate shear strength, midspan deflection, tension reinforcement ...

Deep nulling by means of multiple-beam recombination
Applied Optics, 2003Direct detection of exoplanets is possible by use of a technique called nulling interferometry, which is based on destructive interference of light of the bright object and constructive interference of the faint object. In the infrared wavelength region, this implies that light of a star must be attenuated by a certain factor, the so-called rejection ...

A propped deep beam with opening is considered. This scenario has been the subject of past fib bulletins on strut and-tie modelling. The deep beam has height 4 m and span 11 m. The bottom left-hand corner is supported by a force 3000 kN and the right-hand edge is fixed to an adjacent shear wall. The deep beam is loaded on top by a point load 5000 kN at

Inelastic deformations of wide beams and deep beams
2017Current formulations proposed by Eurocode 8 part 3 for the inelastic deformations of existing reinforced concrete members are assessed aimed at finding out whether they are representative of beams with different cross-sectional aspect ratio, in particular for wide beams (WB) contrasted with conventional deep beams (DB).
