Hi Sean
Iām having trouble understanding what you mean by ā4H10 links per plane.ā Could you please provide me with a visual example or a real-life illustration to help me better comprehend this concept? I would greatly appreciate it.
This just means that if we were to take a cross-section through the beam at a plane where we have provided shear links, there would be 4 vertical shear link bars. So, in lesson 28 at about 28:04, when I show the image of the cross-section, you can see the 4 vertical bars (these are the shear links) in that section or plane.
So, if we increased the spacing between planes, we would need to provide more vertical bars per plane. Conversely, if we reduced the spacing between planes we could provide less vertical shear reinforcement per plane.
