RAM Framing Check for members framing into lateral members

Conner Williamson — Tue, 24 Jan 2017 00:34:15 GMT

Is there anyway to have RAM Steel Beam preform a "Framing Check" on beams framing into a lateral girder? Currently, the framing check report is only flagging gravity beams that are framing into a shallower gravity girder. I know I can make a copy of the model and change all members to gravity elements and then rerun the check, but I am hoping that there is a more effective way to check this situation.

Equivalent Lateral Forces from RAM Frame into Concept

Conner Williamson — Fri, 07 Nov 2014 18:29:57 GMT

Hi,

I have a RAM model with equivalent lateral force load combination. When I bring the mat slab into RAM Concept I can see the ELF load cases (EQ(EQ_ASCE710_X_+E_F....) but the loads from these cases are not being brought into Concept.

All the dead and live loads are being brought in just fine. Can the ELF cases be brought into Concept and if so what procedure should I be following?

Thanks

Integrated Structural Modeling (ISM) Between RAM and Revit

Conner Williamson — Sat, 08 Nov 2014 02:11:03 GMT

I have downloaded and installed the ISM Revit plug-in. The functionality appears to have been added to Revit. But in RAM it is still showing as not installed.

Is there an additional plugin that is required for RAM to work? I am using Revit 2014 and RAM 14.06.01.00.

Below are screen shots of what I'm seeing. Thanks.

Roof Live Load and Snow Load

Conner Williamson — Fri, 06 Jun 2014 23:52:25 GMT

I have a steel frame model in RAM Structural System. The beams are being designed for both roof live load and snow loads. In the criteria I have "Consider Snow Loads, Ignore Roof Live Loads" checked. But the calculated moment is including: DL, LL and Snow. From what I have read RAM SS is only supposed to consider one or the other, either roof live or snow. When I click the option to only consider roof live load, the snow load goes away and the moment is calculated as anticipated. Is there anything else besides the option to "Consider Snow Loads..." that may contribute to the roof live load being considered?

I can set my roof live load to 0 psf to get the desired loading, but I would like to know what RAM is doing.

I am using version 14.06.01.00.

Thanks.

How to account for a suspended slab in pile cap design?

Conner Williamson — Fri, 03 Jan 2014 18:29:37 GMT

I have a working model of a steel moment/braced frame building that I am using to size piles cap foundations (which works just fine).

I am now trying to add a suspended slab to the model, and re-size the pile caps. I have added a new level to the model, with a minimum story height of 0.1ft. On this level I have modeled concrete beams between the columns and added a concrete slab. I have replaced the columns on this new level with large 0.1ft tall concrete columns for the concrete beams to frame into. As the model is set up the decks/slab are not included in the self weight of dead loads or story masses, the dead load and mass are prescribed as surface loads on each floor level.

However when I run RAM Frame, I do not see the dead load or live load contribution from the suspended slab level. The contribution of the concrete beams at this level are being taken into account, but not the suspended slab.

Am I approaching this problem incorrectly? I just want to be able to add a suspended slab dead load to size the pile caps, is there an easier way to accomplish this?

Thanks.
