Selecting a Safety Factor for Stone Concrete Construction ...

Apr 01, 1990  Safety factors for stone have always been conservative compared with safety factors for ductile materials like steel. NEW PROPOSALS The desire to make natural stone more economical has encouraged-and required-the development of several newer, rationally determined design methods. Most of the new proposals for stone safety factors are controversial.

Colored Gemstone Value Factors - GIA

Aug 09, 2018  Value Factor #5: Colored Stone Clarity. Clarity is an important value factor because gems are cut to sparkle and show off their color in interesting ways. If there are flaws that interrupt that sparkle, the gem is less interesting. Hence there is a value curve related to clarity that is also true for each type of gem (see Fig. 1-07).

Factors of Safety - Engineering ToolBox

Factors of Safety - FOS - are a part of engineering design and can for structural engineering typically be expressed as FOS = F fail / F allow (1). where . FOS = Factor of Safety. F fail = failure load (N, lb f) . F allow = allowable load (N, lb f) . Example - Structural Steel Column in a Building. Due to buckling the failure load of a steel column in a building is estimated to 10000 N.
