Section 4.4.0. Single Load Path Structure
For a single load path structure, the only means to protect the
safety is to prevent the damage growth from degrading the strength of the
structure to less than the design limit load.
This applies for all structures classified as slow crack growth,
regardless of the type of construction (such as single load path or multiple
load path). The residual strength
capability of the structure depends mainly on the material’s resistance to fracture.
