The force required by the expansion joint to accommodate expansion is the force that overcomes the stiffness of the expansion joint

Dear experts, in Teacher Tang’s book \"Stress Analysis of Pressure Pipes\", is the force required for expansion joints to expand and contract the force needed to overcome the stiffness of those joints? And is the static axial force generated on the expansion joints equal to the effective area of the bellows multiplied by the pressure?
Isn’t the chapter on expansion joints in that book written very clearly? Axial resultant force = pressure thrust + expansion joint thrust + guide frame friction force.
In the book, Fp denotes the pressure thrust of the bellows； Fs: Represents the static axial thrust exerted by pressure on the expansion joint; these two forces are likely to be the same force, that is, the pressure thrust you mentioned. The thrust exerted by the expansion joint refers to the elastic force generated by the stiffness of the expansion joint
