(a) is maximum at neutral axis
(b) decreases below the neutral axis and increases above the neutral axis
(c) increases below the neutral axis and decreases above the neutral axis
(d) remains the same in both above and below the neutral axis
Diagonal tension in the beam increases below the neutral axis and decreases above the neutral axis. Tension in a beam is the part of the concave face that lies upward to the neutral axis.
Diagonal Tension in Beam
- This stress, known as diagonal tension induced by shear, cannot be countered by concrete on its own. It is created in the tensile zone of the beam at or close to the supports. In order to handle the diagonal tension and prevent beam cracking, shear reinforcement is included in R.C.C. beams.
- The tensile zone of a beam is where diagonal tension occurs; typically, the tensile zone is below the neutral axis and the compression zone is above. As a result, where there is more shear force, the diagonal tension increases below the neutral axis, and it decreases above. Below is a diagram illustrating the distribution of shear stress along a beam’s depth.
- As a result, the diagonal tension in the beam rises below the neutral axis and falls above it.
Summary:
Diagonal tension in beam _____. (a) is maximum at neutral axis (b) decreases below the neutral axis and increases above the neutral axis (c) increases below the neutral axis and decreases above the neutral axis (d) remains the same in both above and below the neutral axis
Below the neutral axis, diagonal stress in the beam increases, and above the neutral axis, it decreases. The structural element that primarily resists loads applied laterally to the beam’s axis is called a beam.
