Is it ok if we input friction coefficient factor mu as zero for fixed saddle?or It shall be inputted as sliding saddle.

If you observe in calculation pvelite consider shear force in anchor bolt calculation that is higher of both the saddle.

This force will be also utilised rib unity check.ultematly we will provide both the saddle with same geometry.

I cant found any advantage in using zero mu for fixed saddle.

Please share your view.

Dear moderators please clarify what exactly to be inputted.

Hi Mitul,
I have never worked on this. But I understand that, if the saddle is fixed, it will have some horizontal reaction due to transverse or horizontal loads (which may occur due to thermal expansion of vessel or any other transverse loads). If coefficient of friction is zero, then there wont be any horizontal reaction (shear force = Mu*Vertical reaction). Thus it would be a case of perfectly smooth surface.
