Per the IEEE Std 605, It does appear that only the maximum rigid bus support spacings and the maximum vertical deflection are impacted by the type of fitting used (2 pinned ends, 2 fixed ends and 1 pinned end & 1 fixed end). The short circuit force is calculated without reduction factor as indicated below.

is there any software that can calculate cancel down effect of short circuit forces on adjacent terminals of a single node connections. That is, connections that are in continuity like in the case of CSE then SA, then from SA to CVT, and then from CVT to WB. If there is any research paper on it, do share. Or any software to find out the resultant short circuit force on every node.
Please find attached the image. In this image, a = 2x240 sq.mm Cu conductor
Static & Short Circuit forces coming by AIS cable software are:
In between CSE and SA = 310N (Static), 2.32kN (Dynamic)
In between SA and CVT = 235N (Static), 2.238kN (Dynamic)
In between CVT and Wall Bushing = 73N (Static), 2.063kN (Dynamic)
The problem is my SA terminal, SLL = 1.43kN, SSL = 2.05kN
and my CVT terminal, Static = 1kN and Dynamic=1.4kN
I cannot change the connections from double copper conductor to tube, neither I can connect CSE with Wall Bushing directly and give jumper to SA and CVT. My equipments are already ordered.
Can you please suggest any solution. I have used T-type connector on SA and CVT. And their terminals bearing forces loads are less than the short circuit forces coming.
