Yes, I think it's fair to frame it that way. This morning I tried taking the quantity of reinforcement in each direction calculated per the Foster equations and then plugged it all back into equation 7.2.4(3). As expected, the total capacity provided was equal to T*.
So Foster's equations...
That makes sense to me. If you're relying on reinforcement in one direction only then you need a much higher quantity so that the inclined portion can take the entire bursting force. Hence Eqn 7.2.4(3) is specifically for the single direction reinforcement scenario. If sin(gamma) = 90 (reo layer...
Thanks for the reply Just Some Nerd.
I thought it may be a convention thing with a different triangle used, but if you were to run the cases side by side you will get vastly different results.
I believe if you have a vector, in this case T*, and you want the vertical and horizontal components...
Hi All,
A question about the calculations for bursting reinforcement in AS3600/AS5100 (I'll refer to AS3600 as the clause is the same).
My understanding of the intent of Equation 7.2.4(3) is that there is a bursting force acting at some inclined angle, and in the case of providing orthogonal...
Thanks rapt for the follow up and answering all my questions.
I lurk around these forums on occasion and I always find your posts quite helpful; both from a technical perspective but also the insights you provide into the code.
Cheers.
Thanks for the explanation rapt.
Just to confirm was that first sentence meant to read "the requirement for flexure plus longitudinal shear reinforcement longitudinal tension plus axial should not be higher than the peak flexural longitudinal tension plus axial requirement at any point in that...
Hi All,
I've just been looking at some designs with concurrent bending, axial, shear and torsion to AS5100.5
Clause 8.2.8.2 of AS3600 very clearly states that the area of reinforcement on the flexural tension side "need not be more than that required at the section with the maximum tension...
