Design shown after design errors

James Grant — Tue, 27 Oct 2015 17:08:35 GMT

Hi,

I am getting the following errors when I run a Design All in the RAM Steel BEAM/Joist module. In cases where I can't get true composite action, I still want to specify the minimum amount of shear studs. What does the module show when I view the design? The design as if the error didn't exist or taking into account the error?

1. Number of studs required exceeds maximum rows specified

2. Not enough studs for 25% composite action

3. Cannot fit enough studs for 25% composite action

4. Flange width inadequate for stud rows required

5. Rib spacing is greater than maximum stud spacing

6. Rib spacing is greater than user-specified maximum stud spacing

Also, why does the program specify zero studs sometimes (and then return error 2 above) when I haven't told it to do this? I have to go in and manually change it in these cases which is a hassle.

Thanks!

Inputting hanging columns

James Grant — Tue, 14 Jul 2015 17:17:48 GMT

I cannot find much help with using the hanging column feature. Am I supposed to input the hanging column on the floor that is hanging then add the regular column two floors above? That would leave no columns inputted on the floor in between which does not seem right.

Thank you!

RAM Steel Beam module not using studs

James Grant — Tue, 22 Dec 2015 19:33:38 GMT

I am using the RAM Steel Beam module and it won't design a few beams using studs. The initial "design all" designed these beams with errors saying that there were "Not enough studs for 25% composite action (0%)." I tried to manally input the studs using the "View/Update Beam" command but it returns the same error and shows that zero studs were used in the analysis by changing my input back to zero. The beams are long enough for studs to be used; it just seems like the program refuses to use studs in the design.

Thanks for the help!

Unstable Structure-RAM Concept

James Grant — Fri, 18 Sep 2015 20:41:51 GMT

Hi,

I made my first RAM Concept model and it's returning the error "Pardiso Internal-Unstable Structure". Do you have any recommendations as to where to start to solve this problem? I've looked at all of the tendons and they seem to by fine.

My structure is just a single story with simple area dead and live loads. The columns have rollers at the far ends and not "fixed far."

Thanks!

Camber in updated beam designs (RAMSS)

James Grant — Thu, 10 Sep 2015 13:43:43 GMT

In the RAM Steel Beam/Joist Module, what happens with camber once you manually update a beam's design using the View/Update command? Is there no way to include camber when doing it this way?

I like to get my stress ratios under 0.90 in early designs but I noticed that none of these beams include camber once I update their design manually.

Thanks!

lateral reactions at base of braced frame

James Grant — Wed, 19 Aug 2015 21:57:58 GMT

I need to give the lateral reactions at the base of my braced frames to a foundation consultant, preferably in both ASD and LRFD, so they can design the baseplates and foundations. I also need them broken out into wind and seismic contributions. How would I do this in RAM Frame?

I've already assigned frame numbers and looked at the frame reaction reports but I don't think I can get the values I need from these reports.

Thank you!
