Hi,
We have got a max of -16mm of settlement available for civil piling as specified in Civil design basis.

My question is :
1)Is there ant guidelines/Basis which says upto how much amount of settlement (say -5 or 6 mm) can ignored for consideration of stress analysis?.
2)Will there be different settlement at each bay of support for pipe rack.
e.g. first support can be considered as 0mm deflection while second will have -16mm of settlement?

Can anyone with experience in such a design share the info.on the subject matter.

Regards,
raj
