1.1 The purpose of this standard is to provide
procedures and relevant design parameters of limit state design of
cargo containment systems of a novel configuration in accordance with
section 4.27 of this Code.
1.2 Limit state design is a systematic approach
where each structural element is evaluated with respect to possible
failure modes related to the design conditions identified in section
4.3.4 of this Code. A limit state can be defined as a condition beyond
which the structure, or part of a structure, no longer satisfies the
requirements.
1.3 The limit states are divided into the three
following categories:
-
.1 Ultimate Limit States (ULS), which correspond
to the maximum loadcarrying capacity or, in some cases, to the maximum
applicable strain, deformation or instability in structure resulting
from buckling and plastic collapse; under intact (undamaged) conditions;
-
.2 Fatigue Limit States (FLS), which correspond
to degradation due to the effect of cyclic loading; and
-
.3 Accident Limit States (ALS), which concern
the ability of the structure to resist accident situations.
1.4 Part A through part D of chapter 4 of this
Code shall be complied with as applicable depending on the cargo containment
system concept.
