I have a plan check comment stating that a 1.5 F.O.S. is required for gross overturning on any building shear wall from seismic loads at ASD level. The project is under the 97 UBC; I have been unable to find any code section that requires a 1.5 F.O.S, the only requirement is for earth retaining walls. Could anyone please comment on where I can find the section? Or how they have resolved a similar situation?
Thank you
