Biaxial Pier Stem Design
Biaxial Pier Stem Design
(OP)
Is there any widely accepted design methodology for pier stems on isolated footings with large biaxial bending moments?
Can the stem be designed as a doubly reinforced beam with moments in each direction being independently analyzed?

Any good column design software such as PCACOL should be able to do the job.

Its an odd situation....
There are very high moments with almost negligible axial load....hence I'm not so sure a "column" design is even appropriate.
I think what I basically have is a cantilever beam with biaxial moments.
I'll admit, I am a steel guy with some basic foundation design knowledge and this is a first for me.
I am very familiar with "normal" spread footing design as well as concrete beam design theory.
Would designing this as a cantilever biaxial concrete beam make sense? If so, is a regular bi-axial interaction equation like you'd find in steel appropriate?
Thank you
