Software for Generating and Applying Design Loads

Software for Generating and Applying Design Loads

Software for Generating and Applying Design Loads

(OP)
Every time I begin a project in Revit and start developing loads, I get so frustrated!

We follow code procedures (ASCE 7) and generate loads based on the buildings geometry and material.  If I just spent all this time to put together a model for drafting and coordination with the Architect, why not use the model for something more to save time?  

I'm not looking for analysis programs...  I'm looking for software that develop loads based on the model, taking the dead loads (based on the material of the model)/live loads/snow loads down through beams/walls/foundations while applying wind/seismic through the diaphragms rigidity.

I understand this is our job as structural engineers but couldn't we be more efficient?  We have so much potential with computers to do accomplish this.  Someone please tell me this software exists!!

RE: Software for Generating and Applying Design Loads

RAM - RISAFloor are two that allow area loads to be applied and design full framing.

I'm not sure why you say "I'm not looking for analysis programs" and then ask specifically for a program that does analysis.



 

RE: Software for Generating and Applying Design Loads

With RAM and RISA, the loads have to be inputted by the user.  The point I was trying to convey is since the 3D model has the geometry and materials already, the loads themselves should be able to be generated.  RAM and Risa might be able to do this based on ASCE 7.  I'm not that familiar with them, are they capable of doing this?

(And of course, if the program can do the analysis as well, even better.)

RE: Software for Generating and Applying Design Loads

(OP)
Sure enough, Risa does.  Now my next question, does it do it well?  I know there are links between Revit and Risa.  Do you find this useful for wood buildings?  In my experience, most of the people use Risa for steel/concrete buildings.

RE: Software for Generating and Applying Design Loads

So you'd like a software program that all you have to do is make a model, pour a fresh coffee, put your feet up on the desk, and push a button?
 

RE: Software for Generating and Applying Design Loads

also, with any modeling/design software, whether it be RISA or STAAD or whatever requires some user input (engineering) to assure the building model functions like the building will.  

RE: Software for Generating and Applying Design Loads

Sounds like you need to hire a structural engineer to do all the work for you.

RE: Software for Generating and Applying Design Loads

I sort of feel the pain because I did not have to do drafting when I was an engineer - employee, and back then the Code was much simpler without all the load cases etc.

Now that I am self-employed, I just use all my Excel that I have developed over 2 decades (basically a total design workbook for custom houses). It isn't as automatic as what you are looking for, but it helps enormously to prevent burn-out.

There is software that automatically designs (from AutoCad) structural components for the entire wood building, but it was developed offshore and is very buggy.

RE: Software for Generating and Applying Design Loads

The holy grail of structural engineering.  Yeah, it might exist but you must be noble of heart.

Anyone here use (used) Tekla Structures?

RE: Software for Generating and Applying Design Loads

(OP)
Thanks for the sarcastic answers.

AELLC, that's pretty much what I'm feeling too.  I feel like I'm duplicating efforts and creating something that has so much potential but just gets shoved aside because I'm not an "engineer if I don't use paper".  I've been told several times over to not use Risa and do things by hand.  I might as well bust out an abacus and chisel while I'm at it...

RE: Software for Generating and Applying Design Loads

If the abacus and chisel gets you from point A to point B quicker-Go for it.

When appropriate, I like computer programs as design aids. But when it takes 10 minutes to enter data, or 2 lines on a piece of paper- paper wins. Part of being an engineer is finding the most efficient methods, not just the one with the most bells and whistles.

RE: Software for Generating and Applying Design Loads

There is only a slim chance that a wood structure's model will behave like the actual building will. (as mentioned by ToadJones)

On the other hand, if you have a major steel or concrete building, then automation begins to make sense.

RE: Software for Generating and Applying Design Loads

I have used Tekla
