(1) In RAM Frame, create an “equivalent” static load case using a User Defined Story Force, one that generates the same total shear at each level (usually determined from the building story shear report). Then import the reactions from this static load case into Concept.
(2) In Concept, manually create a new seismic load case (Criteria – Loading – New, with type normal). On the load layers for that loading, add point loads (or line loads) based on the reactions from RAM Frame. Be aware, that a dynamic analysis, by default, produces forces all of like sign. If you are not already considering sign in the RAM Frame analysis (Criteria – General), we suggest you do so. Otherwise, manually establish the probable sign for each of the reactions so that the forces input into Concept represent a concurrent event.
