Alternative Methods to Extracting Loads for Foundation Design

Alternative Methods to Extracting Loads for Foundation Design

Alternative Methods to Extracting Loads for Foundation Design

(OP)
Hello guys,

My coworker and I had a discussion about alternative methods of extracting loads for our foundation design. My approach was to mesh my model at 1 ft and go through each elevation checking for a max value for each respective load cases. My coworker's approach was to mesh his walls into 1 foot strips so he could select all the joints at the base level and plot it in a table with their respective load cases/combinations. I am just curious if there is a less time-intensive way as to designing foundations with loads taken from ETABS?

Thanks

Do you have SAFE (CSI's concrete design software)? You can somewhat easily export your reactions from ETABs to SAFE.

Hi @sticksnadtriangles

We have SAFE, however I haven't had too much experience with the program yet. Normally we'd take the ASD loads and enter it into ENERCALC footing modules. That is definitely an option I could consider.

Pier labelling is my preference for walls onto a raft foundation or pile cap. Either method will/should return the same global values for the wall group Fz, Mx, My & Mz (if these are the terms that you are concerned with). If a pile-cap foundation than you may want to include Fy and Fz for shear distribution to piles. Using the pier loads will give a smoothed reaction as you are extracting line loads instead of node loads.

That is actually pretty interesting, I'm surprised I haven't looked at pier labelling as another alternative to load take-offs. Most of the foundations I have worked with have been simple strip & column footings.
