  2. Factor of safety - Wikipedia

    en.wikipedia.org/wiki/Factor_of_safety

    In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.

  3. Structural engineering theory - Wikipedia

    en.wikipedia.org/wiki/Structural_engineering_theory

    The safety factor applied to the load will typically ensure that in 95% of times the actual load will be smaller than the design load, while the factor applied to the strength ensures that 95% of times the actual strength will be higher than the design strength. The safety factors for material strength vary depending on the material and the use ...

  4. Limit state design - Wikipedia

    en.wikipedia.org/wiki/Limit_state_design

    Load and Resistance Factor Design (LRFD), a Limit States Design implementation, and; Allowable Strength Design (ASD), a method where the nominal strength is divided by a safety factor to determine the allowable strength. This allowable strength is required to equal or exceed the required strength for a set of ASD load combinations.

  5. Barlow's formula - Wikipedia

    en.wikipedia.org/wiki/Barlow's_formula

    The formula is also common in the pipeline industry to verify that pipe used for gathering, transmission, and distribution lines can safely withstand operating pressures. The design factor is multiplied by the resulting pressure which gives the maximum operating pressure (MAOP) for the pipeline.

  6. Design load - Wikipedia

    en.wikipedia.org/wiki/Design_load

    For example, a crane with a design load of 20 tons is designed to be able to lift loads that weigh 20 tons or less. However, when a failure could be catastrophic, such as a crane dropping its load or collapsing entirely, a factor of safety is necessary. As a result, the crane should lift about 2 to 5 tons at the most.

  7. Permissible stress design - Wikipedia

    en.wikipedia.org/wiki/Permissible_stress_design

    Permissible stress design is a design philosophy used by mechanical engineers and civil engineers. The civil designer ensures that the stresses developed in a structure due to service loads do not exceed the elastic limit. This limit is usually determined by ensuring that stresses remain within the limits through the use of factors of safety.

    en.wikipedia.org/wiki/Talk:Factor_of_safety

    As, by definition, the design load times the factor of safety is the failure load. 128.158.1.166 17:50, 28 July 2009 (UTC) There is nothing unclear about the difference between factor of safety and design factor in this article, as read by a Colorado and Texas licensed professional engineer with three engineering degrees.
