When a stand-off with grouting installation is considered, with a strong grouting, does this mean that the grouting is used for levelling? If the grouting is not used for levelling but the member is levelled using levelling nuts but the gap is grouted at a later time, can this be considered to be a stand-off with grouting condition for the anchor assessment with Profis? I don't think that the stresses will be transferred to the grout at a later time as they are locked on the anchors. Wouldn't be more appropriate to do the calculations as stand-off with or without grouting but restraint level 2 as anchors will not be able to rotate?
Yes. The baseplate may be levelled using levelling nuts and subsequently grouted. In PROFIS Engineering, the“stand-off with grouting” condition relates to the final load-transfer condition rather than the method used to level the baseplate.
If the grout fully supports the baseplate, has achieved the required strength, and is in place before the relevant design loads are applied, the final condition may be modelled as a grouted stand-off. If significant loads are applied before the grout has hardened, the temporary ungrouted condition should also be checked.
The restraint level is a separate consideration and should be selected based on the actual rotational restraint of the anchor/fixture connection. It should not be used as a substitute for the grouted stand-off condition. PROFIS Engineering can, for example, model a grouted stand-off with restraint level 2.
