Doing a trial run on RAM Elements, importing a four story building modeled in RAM SS into Elements. All of the components transfer across, but the loads are not showing up in Elements. I have run Beam, Column and Frame analysis, and all "lights" are green. I even changed material on the shear walls from Other (CMU wall in the real world) and ran the Concrete analysis in order to get the gravity loadings applied.
I just realized that I do not have any foundations under the walls or columns, I guess that might be the problem, nope that wasn't the problem. Added footings to the walls, still no loads in Elements after importing the RAM ss model.
There was a seminar on transferring CMU wall from RAM SS to Elements, but it's real-time only, not a recorded seminar, as would be preferable, so I was unable to make the earlier seminar, and other next seminar isn't scheduled until next week.
Any ideas?
Thanks.

Internal forces are not transferred from RAM SS to Elements. Only loading is transferred. Therefore, the model must be reanalyzed in Elements before selecting a wall and entering the wall module. If you are following this process, there are a couple of other explanations. First, two way slab loading will not import. Second, you have to analyze in Frame to get lateral loads for the generated cases.
That makes sense, the slab loading is one-way. The model has been run thru Frame analysis in RAM SS.
Just ran an analysis in Elements (52 minutes, too many load combos) I jump into the CMU wall module, and the geometry does show up, but I'm not seeing any of the point loads from beams bearing on the wall.
The w-beams are in the Elements Model, but there are no loads in the load tables when I'm looking at the properties. Do all the point loads need to be entered by hand, or is there another procedure that I'm not following?
Also, Elements doesn't seem to want to check ASD load combos, the masonry code allows Allowable Stress design, so what else am I missing?
The program imports the internal forces resulting in the FEA in Elements into the wall module. They show up as global forces in the properties. Review the technical notes in Chapter 35 of the RAM Elements manual.
Make sure you have the load case that you are interested in selected when looking at the loads. If you continue to have a problem, please submit a service ticket online and include the RAM SS model. I would need to see your original RAM SS model to determine why you are not seeing loads after importing into Elements.
Load combinations have type design and type service. This does not mean LRFD and ASD. Design combos are used for strength calculations and service combos are used for service limit states like deflection. The design methodology is always selected elsewhere and is completely independent of the load combinations. In the masonry wall module, the current implement only considers allowable stress design. Therefore, all load combinations, design and service, should be consistent with that methodology.
It's making more sense to me now. Thanks again.
