Foreword
Codeofchina Inc. is in charge of this English translation. In case of any doubt about the
English translation, the Chinese original shall be considered authoritative.
In accordance with the requirements of MOHURD Notice on Printing and Distributing the
Development and Revision Plan of Engineering Construction Standards and
Specifications in 2015 (JIAN BIAO [2014] No. 189), this standard is revised by the drafting
team through extensive investigation, careful summarization of practical experience,
reference to relevant international standards and foreign advanced standards and on the
basis of widely solicited opinions.
The main technical contents of this standard are as follows: 1. General Provisions; 2.
Terms and Symbols; 3. Basic Requirements; 4. Principle of Limit State Design; 5. Actions
on Structures and Environmental Influences; 6. Properties of Materials and Geotechnics
and Geometrical Quantities; 7. Structural Analysis and Design Assisted by Testing; 8.
Method of Partial Factors Design.
The main technical contents of the revision of this standard are as follows: 1.
Comprehensive coordination with the Unified Standard for Reliability Design of
Engineering Structures (GB 50153-2008); 2. Adjustment of the setting level of the safety
degree of the building structure, increasing of the value of the partial factors of related
functions; and for the basic combination of the action, canceling of the combined functions
of the original standard that played a controlling role when the permanent load effect is
dominant; 3. Addition of the seismic design status, and introduction of the design concept
of "No damage in small earthquake, repairable in medium earthquake and no failure in
great earthquake" to the seismic design of building structure; 4. Improvement of the
requirements on reliability assessment of existing structures; 5. Addition of relevant
regulations on the overall stability design of the structure; 6. Addition of relevant
regulations on design of limit state of structure durability.
The provision printed in bold type in this standard are compulsory and must be enforced
strictly.
The Ministry of Housing and Urban-Rural Development of the People's Republic of China
is in charge of the administration of this standard and the explanation of the compulsory
provisions; China Academy of Building Research is responsible for the explanation of
specific technical contents. During the process of implementing this code, the relevant
opinions and advices, whenever necessary, can be posted or passed on to China
Academy of Building Research (Address: No.30, North 3rd Ring East Road, Beijing,
100013, China).
