RE: RAM SS: How are live load reductions for line loads determined?
It depends on the code, so check the Ram Steel Beam manual section "10.3.9 Live Load Reduction" for details, but for most cases we determine a tributary area for the beam. Once we know the tributary area we calculate the live load reduction percentage…
RE: Column not spliced but size is changing between floors
If you see a "Y" in the column view/update dialog box in the "Splice" column that means the column in question has a user assigned splice which can come from the story data or from an extra user-assigned splice in the column module. You can clear user…
RAM Steel - Joist equivalent load calculation
Can anyone explain the values given in the report for design loads?
Is this based on max moment, shear or deflection?
I can't seem to replicate this calculation and it seems that it overestimates the equivalent load for deflection calculations.

Roof Live Load and Snow Load
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…
RE: RAM-SS Cantilevers
For those of you who don't have the ASCE 7-05 handy, this special seismic provision basically says that cantilever beams should be designed for a minimum net upward force of 0.2 times the dead load.
We don't automate this in RAM SS right now. We do…
RE: RAM SS Column Module is Missing some HSS sections
Just edit the Column Design Table to include a group for the HSS 10x4s. Ram Manager manual, Section 7.5.3 Column Design Tables has details.
RE: RAM Steel Beam vs Frame
The braces are not considered in the Ram Steel analysis. The comment from the Analysis Notes wiki that everything is pinned is an oversimplification. Cantilever beams and Stub cantilevers are still treated as fixed. I'll edit that wiki in a moment to…
Ram Frame Pnt > Pe2x errors
I have a 4 story building that is "L-shaped". Currently I have moment frames from the foundation to the roof in both wings and I've even tried having some down the middle. I followed the Ram Frame tutorial as best as I could (no pictures), but I seem…
