What type of expansion joint is shown in the image? The one with the large tie rod? Why are add-on moment and friction force included in the design parameters, and how are they taken into account in the simulation calculations of the CII model?

My English isn’t good; from the picture, it seems to be a double-hinge type compensator

Like multi-layer universal hinge-type expansion joints

There is an extra pin in the middle; I’m not sure what its purpose is.

I’m not a professional technician; it’s just my personal guess – it’s probably for the purpose of stabilizing the pull plate
