Roof Live Loads vs. Snow Loads RAM SS

Has this been done yet?

6) Snow Loads versus Roof Live Loads

Within the Criteria -> Member Loads menu in RAM Manager there is an option to consider either roof live loads or snow loads during the gravity analysis of the structure. Currently it is not possible to consider both types of loading simultaneously. Later this year (2010) this limitation will be removed.

I read this on Josh Taylor's blog and I was wondering if this had been added to RAM SS yet?

  • Any more updates on timeline for this? We also run into cases where we have live loads and snow loads applied to a balcony. This isn't a big deal in low snow areas, but leads to some headaches when you're consistently seeing high snow loads.

    Is there even actually a plan to fix this? OP posted stating the original timeline was 2010 and now 7 years later we haven't seen the fix...

  • Unfortunately this annoying limitation is still in the same situation as it was 7 years ago. With limits on resources we have had to focus on more critical items such as Code updates and more advanced analysis, design, and reporting capabilities such as Diaphragm cross section forces and Construction sequence analysis, to name just two. We recognize that we need to modify the program to provide for both Roof and Snow loads, as well as Wind uplift. A surprising amount of work due to the complexity of the surface load distribution and load tracking algorithms. We actually started work on them, but had to divert the resources to something more critical. So while we recognize the need, I can't even guess when we will be able to implement those changes.

  • Well, at least roof live load, snow load, and wind uplift are rare loading conditions that hardly ever occur on the vast majority of jobs... oh wait, never mind... But I suppose it is easier to market cool new advanced features than to say you've finally fixed basic functions after an awkwardly long time.
