The utility of your software tools will be very limited if you are restricting yourself to only member design instead of total structure solutions like ETABS. Why should engineer pay you at all if they can use spreadsheet for free to do what you do with your SaaS?

> No one I know is using the automated concrete design built into analysis programs like ETABS, Tekla, etc.

Not too sure about this because I know quite a lot of people who are using these tools. Any reason why the people you know don't use ETABS or Tekla?

Why do businesses invest in new tech? Why pay for excel when I can use a pen and calculator? The answer is because it makes them more efficient. We have excel sheets to do the same thing, matlab code to do the same thing, and yet here we are paying for these member design tools because they are the most efficient for us. If you save an engineer even a couple of minutes for each element they are designing, you essentially pay for the software.

We do use ETABS extensively for analysis. We don't use it for design. It is foolhardy to trust the automated RC design in these software. That seemed to be the standard of practice around here, but perhaps it is different in other areas of the world.

Do you mind if I ask why? I'm working on a sort of general approach toward designing trustworthy engineering software, and I'm trying to collect as many reasons as possible for "can't trust the software".

Since you can already do the analysis (like ETABS), and you are planning to do individual member design, why put the two and two together and do an automated RC analysis+design software? There is no reason to distrust an automated software anymore than separate analysis+design software.

[ggcdn]

There absolutely is a reason: seismic design. We end up doing a lot of data manipulation between the FEA stage and member design stage.

Its not a distrust so much as a fundamental flaw. For simple gravity design it works fine, but even then we are using spColumn because its just quicker for us.

Care to explain why you have to manually do lots of data manipulation between FEA and member design? Why not write a software that can automate these whatever data manipulation? Seems to me that an All-In-One software should have no problem doing analysis, the-whatever-data-manipulation, and the member design.
