Factor safety sliding
WebI am familiar with a typical FS of roughly 1.5 against sliding forces due to active soil pressure for the design of many types of structures (including cantilevered retaining walls and gravity dams), but I am not aware of any such standard FS against uplift. ... It is … WebNov 19, 2015 · If you're using unfactored loads, then yes, you want the factor of safety of 1.5. Swiver -- depends how dead your dead load actually is. I've also seen the 0.9 value as a conservative (or realistic) proportion of DL to use when it is beneficial to your system. I have used the 1.5 FS for overturning since late 1970's.
