Re: ETABS V7.17 - R/C Design

Mr. Gillham
I used ETABS V7.17 for a 8 story smrf structure in Taiwan. I faced the same question as you are. In the RC design procedure, the the etabs just shows the "very helpful" message "Error during concrete design of frame nnn" in beam design. But, it goes well in column design. Here are some notes might be useful, but I can not make sure if it works. There are still some bugs in Etabs 7.17, but much better than patch 7.1.
1. Try to export your model into e2k file and import again.
2. Make sure the design procedure is rigth after the analysis procedure. If you already take any other action after the analysis procedure, do the analysis the model anagin.
3. Try to use lb-in unit system if you find any design error. Export to e2k file and import again. There are some bugs of the unit change in design program.
Hope this will help.

Subject: ETABS V7.17 - R/C Design

I'm TRYING to use ETABS V7.17 (latest patch) to do a quick ACI 318 design (for checking purposes) on a 5 story building.  I have SMRF ("special sway" designation by ETABS) members, and I simply cannot get the darn thing to do a design run.
My analysis runs fine, but when I
1)    do a design of the whole structure (all R/C elements)
2)    do a design of an individual member (column or beam)
3)    try to run the interactive design of an individual member (column or beam)
the program returns the extremely descriptive error message "Error during concrete design of frame nnn" -- very very helpful.
The thing is, I got the program to do a design run once before, ON THE SAME EXACT MODEL, but I can't get it to do it again.
So, my question is: Has anyone else run into a similar problem, and if so, did you find out how to work around it?  Even an answer to the effect that no one has found a work around would be helpful since I will junk this approach in favor of one less akin to beating my head against the wall.
Any comments would put me in better shape than I am now (since I have to get this out within the next couple of days and there are about 1000 members total in the structure!)
Thanks in advance.
