WebIn general, the greater the uncertainty the higher the required FoS to achieve a minor probability of failure. When seismic slope stability analysis is conducted, the equivalent minimum factor of safety may be reduced to 1.10. An earthquake force is a dynamic load that lasts for a short period hence a lower FoS can be assumed. WebNotes. NOTE 1 Factor of safety is synonym of safety factor. NOTE 2 FS and SF are also recognized abbreviations used for factor of safety. NOTE 3 The factor of safety is a combination of factors according to various sources of uncertainties. Its magnitude is based on proven processes and verification methods for analyses, tests and manufacturing. foot folding
