Scope

1.0.1 This standard is hereby formulated, in order to unify the basic principles, basic
requirements, basic methods of the reliability design of building structures of various
materials, so that the structure meets the requirements of sustainable development, as
well as the requirements of safety, reliability, economic reasonableness, advanced
technology, quality assurance.
1.0.2 This standard is applicable to the design of the entire structure, the components
that make up the structure, and the foundation. It is applicable to the design of the
construction stage and use stage of the structure. It is applicable to the reliability
assessment of existing structures. The reliability assessment of existing structures can
be carried out, in accordance with the provisions of Appendix A of this standard.
1.0.3 This standard is formulated, based on the principles of the current national
standard "Unified standard for reliability design of engineering structures" GB 50153.
It is the basic requirement for the reliability design of building structures.
1.0.4 The design of building structures should adopt the limit state design method, based
on probability theory and expressed by partial factors. When there is a lack of statistical
data, the design of building structures can be based on reliable engineering experience
or necessary experimental research, OR it can be carried out, using the empirical
methods such as allowable stress or single safety factor.
1.0.5 When formulating load standards for building structures, structural design
standards for various materials, and other related standards, it shall comply with the
basic criteria, which are stipulated in this standard; meanwhile formulate corresponding
specific provisions.
1.0.6 In addition to complying with the provisions of this standard, the building
structure design shall also comply with the provisions of the relevant national standards,
which are currently in force.
