I have two questions that
1- When the Code edition Asme B31.3 2014 and later, I will use the "Remove Lift-off Supports" option in the analysis set and re-run the calculation. Then I will re-check the support loads and analysis results Then I will consider the worst scenario for loads and stresses by comparing the unclicked "Remove Lift-off Supports" option.
In this case, must I remove the lift-off supports manually and re-run the calculation? Software is already removing the lift-off supports.
2- If the lift-off guide support has been restrained vertically such as U type bolt and it allows only axial movement of pipe, Can I neglect the lift-off support warning?
