Hi, this is very helpful. I did not fully understand: first, where does the diagonal tension force come from? Is this because a force has to resist the cracking from getting wider and the only force that can do that is the tension from the stirrups acting diagonally? Second, why is there a diagonal compression force in the concrete? Is this to balance the tension diagonal force on an element of concrete? However, this seems to assume that the concrete element is in equilibrium but if cracks are forming then is it in equilibrium?
That's a pity that you didn't continue this subject. The necessary calculations of making a truss is very interesting.
Thanks Krishna, you have answered my thoughts
very good video.
The answer I was looking for!
Video is helpful. Thanks!
Thanks !
