According to the requirements of Document Jian Biao ［2003］ No.102 issued by the Ministry of Construction—"Notice on Printing the Development and Revision Plan of National Engineering Construction Standards in 2002 and 2003",China Academy of Building Research made a comprehensive revision for the national standard "Unified Standard for Reliability Design of Engineering Structures" GB 50153-92 jointly with the departments concerned.

This standard was revised by borrowing actively from the international standard ISO 2394:1998 "General Principles for Structural Reliability" issued by International Organization for Standardization (ISO) and the European standard EN 1990:2002 "Bases of Structural Design" approved by European Committee for Standardization (CEN),carrying out the principle of preceding from the actual conditions of China carefully,summing up the practical experience of Chinas large-scale engineering and carrying through the guiding principle of sustainable development.There have been some significant extensions in this revised new standard over its previous edition.This revised new standard specifies the basic contents on the design basis of engineering structures and is a basic standard for design of engineering structures.

This revised new standard uniformly specifies the fundamentals,basic requirements and basic methods for the design of engineering structures in various civil engineering fields such as architectural engineering,railway engineering,highway engineering,harbor and harbor engineering and water conservancy hydroelectric engineering,in order to make these=engineering fields be provided with consistency and coordination on processing the structural reliability problem and link them up to the world.General requirements for the design of engineering structures in various civil engineering fields are included in the text of this standard,while the specific requirements for special branches and problems are included in the Appendixes.The main contents of this standard are as follows:General Provisions,Terms and Symbols,Basic Provisions,Limit State Design Principles,Actions and Environmental Influence on the Structure,Material and Geotechnical Properties/Geometrical Parameters,Structural Analysis and Test-assisted Design and Partial Factor Design Methods.

The bold provisions in this standard are compulsory provisions and must be enforced strictly.

Ministry of Housing and Urban-rural Development is in charge of the administration of this standard and the explanation of compulsory provisions.And China Academy of Building Research is responsible for the explanation for the specific technical contents.In order to improve the standard quality,all relevant organizations are kindly requested to sum up and accumulate-experience in practices during the process of implementation of this standard.The relevant opinions and advice,whenever necessary,may be posted or passed on to China Academy of Building Research (Address:No.30,North Third Ring East Road,Beijing,100013,China) for future reference.
