RE: Undergraduate modeling 5 story structure in RAM Structural System

1. For basics on entering loads, the Ram Tutorial is best (online wiki here: communities.bentley.com/.../ram-modeler-tutorial) Other tips on gravity loads are here: communities.bentley.com/.../ramss-gravity-loads-faq.aspx. Roof loads are typically different than floor loads.
2. This in in RAM Frame Analysis module - Loads - Load cases.
3. Modeler - Elevation view - Layout - Braces, again refer to Tutorial.
4. Layout - Columns - Assign frame fixity from Modeler or Ram Frame.
5. See this topic: communities.bentley.com/.../ramss-seismic-loads-faq We expect some of the data to be input as part of the seismic load.

Daniel, the answers to your questions are more involved than can be accommodated here, but I recommend that you look at the Tutorial Manual. It demonstrates most if not all of this. In short, Gravity loads are defined and assigned in the RAM Modeler, and Roof loads and Floor loads are explicitly identified as such. Braces are modeled in Elevation view in the Modeler. Member fixity is assigned in the Modeler but can also be modified in RAM Frame. ASCE 7 Wind and Seismic loads can be automatically generated by putting in the appropriate parameters, in the RAM Frame Loads - Load Cases command. ASCE 7 Response Spectra curve is explicitly implemented in RAM Frame Loads - Load Cases, but you can also create files representing any RSA curve that you desire and invoke that; the format of that file is described in Section 7.18 of the RAM Manager manual, and the file needs to be put in the RAM Tables directory.
