Not illustrated. 1911 Excerpt: ...Considering the amount of stress so transmitted to be distributed over a horizontal plane of unit length extending across the width b of the beam immediately above the reinforcing bars, and denoting the unit horizontal shearing stress in the concrete by the symbol s, we have so = sb (94 Then, for the unit horizontal shearing stress along such a plane in a rectangular beam with single reinforcement, we obtain--S (95) M1-V 37 Formula? (91) and (95) can be modified to suit other types of beams, as explained in paragraphs (i) to (iv), article 56, and in accordance with paragraph (v) of the same article we can employ (95) for approximate calculations in the form--s = yd (96j As at any point in a beam the horizontal shearing stress is accompanied by vertical shearing stress of equal intensity, formulae (91) and (95) also give the value of the vertical shearing stress. It should here be noted that while in a homogeneous beam the distribution of horizontal shearing stress is represented by a diagram of parabolic outline as in Fig. 73, the intensity of horizontal shearing stress in a reinforced concrete beam, where no tension is assumed to be taken by the concrete, may be regarded as uniform between the centre of the tension reinforcement, as shown in Fig. 74, but above the neutral axis the diagram is bounded by a parabolic curve similar to that for a homogeneous beam. Example 69.--For the beam described in Example 4, article 12, find the horizontal and vertical shearing stress along a plane of unit length immediately above the reinforcing bars at the three points stated in Example 68. As 58. Tension on Diagonal Planes.--The most recent tests of reinforced concrete beams show that, in failures by diagonal tension, the vertical shearing stress rarely exceeds 150 poun...
