hi
I have a question regarding the expansion joint modeling in CAESER,in reality we are introducing bellows and rigid element with degree of freedom restrains depending in expansion joint type so my question is how to obtain the parameters of the bellows (axial stifness,lateral stiffness,bending stiffness and the allowables axial,lateral and bendind displacements)these prameters are not available in suppliers catalogs we find only for example for gimbal joint the bending stiffness and the allowable angle rotation for the hole mechanism.
Should we calculate these parametrs by our self following for example the EJMA standard or there is another way.
thanks to clarify this point for me.
