A nonlinear theory for multilayered shells is particularized for deep beams. The results are linearized and applied to small deflection analyses of such beams. In the solution, a finite difference scheme is used which takes advantage of the fact that higher derivatives of variables do not all appear simultaneously in any one equation, thereby admitting

Abstract This paper presents a method of analyzing the stress distribution in a deep beam of finite length by superimposing two stress functions. The first stress function is chosen in the form of a trigonometric series which satisfies all but one of the boundary conditions—that of zero normal stress on the ends of the beam.

Abstract The paper considers deep beams simply supported (by columns, in shear wall construction, hoppers etc.) where support conditions approximate to a parabolic shearing force on the vertical end faces of the beam. An approximate polynomial stress function solution is first obtained which does not satisfy all the necessary boundary conditions ...

Beams whose depths are comparable to their spans are used in a variety of structures. The distribution of bending and shear stresses in such deep beams departs radically from that given by the ordi...

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).

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 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.

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.

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

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.
