Is retaining wall a non building structure(NBS) ?. Is it mentioned any
where in UBC-97 ?
I am designing a filter plant structure. For soil seismic force I am using
a formula with R value of 2.7. So It appears that I can assume the
retaining wall as NBS
I would like to know if there is a standard practice to assume the retaining
wall as a NBS. Or should I determine the EQ forces per UBC-97 section
1632.2 for element Also please let me know a reference which has design of
retaining wall for EQ forces.
Thanks in advance. Sid LaKhani
