There are several ways to compare the factor of safety for structures. All the different calculations fundamentally measure the same thing: how much extra load beyond what is intended a structure will actually take (or be required to withstand). The difference between the methods is the way in which the values are calculated and compared. Safety factor values can be thought of as a standardized way for comparing strength and reliability between systems. WebJan 1, 1998 · The bolt load is 450 lb per bolt for a four-bolt pattern. Referring to Table I, the use of 1/4-20 steel bolts would provide adequate strength and a factor of safety of 1750/450 = 3.9. This may be a larger and more prudent bolt size selection than previously calculated for the working pressure design criteria.
