RAM Drift Module
RAM Drift Module
(OP)
I was wondering if anyone had any experience with the RAM Drift Module. We plan on buying it to use it for 14+ story buildings. Please share your thoughts.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: RAM Drift Module
RAM requires the user to setup virtual load cases for each and every direction and story that deflection is to be considered. This seems to be a lot of extra work, and I cannot imagine that it would be extremely useful or efficient as opposed to just the engineering judgement approach of looking at the deflections of the building and increaseing beam then column sizes to control drift - BUT I have never used it so maybe it is great.

RE: RAM Drift Module
I've used this stuff before and have found it to only be marginally better than just using engineering judgment. It CAN be useful, but there are also lots of times when it gives nonsensical answers. There are so many design constraints, like wanting equal depth members, etc., that a lot of engineering judgment is still required.
Strangely enough, I think one can do pretty well by just using all small members in the moment frames for the first try. Look at the strength ratios (all will be no good by a wide margin) to get a very rough idea of what's doing the work. Then bump members up from there, using engineering judgment.

Boiler, ive never heard ram was on its way out. im curious, where does that come from?
