hokie66,
Thank you for the feedback, I am not a developer, just a user (4 years until now) and I prefer using the PLPAK because of some things it facilitates, and I have done several practical examples such as foundations and post-tensioned slabs with it. I was asked to specify the reason why...
rapt and rowingengineer,
The codes use empirical methods because the FEM is deficient as you know. I check with the developers and found this:
The shear calculation is ignored in the basic derivation in the finite element analysis, then it is calculated backward using simple equilibrium...
rapt,
I will check in more for why boundary element method developers think that punching shear is more accurate using their software and reply as soon as I can.

rapt,
Thank you for the heads up, I really appreciate the support from you since I am new here.
I was just pointing out that the boundary element method can solve the near exact punching shear around any columns in slabs. That is possible because the whole geometry of the column is taken, not...
Slickdeals - I would suggest using a different software to those who utilize the finite element method (FEM) in post-tensioned slab analysis. The boundary element method (BEM) diminishes almost all the mishaps that appear in the FEM.
For example, columns are represented by their true geometries...
