Notice on the Release of the Standard "General Symbols, Units of Measurement and Basic Terms for Building Structure Design" Standard Planning Standard [1985] No. 1957
According to the notice of the former State Construction Commission (82) Construction No. 20, the standard "General Symbols, Units of Measurement and Basic Terms for Building Structure Design" jointly compiled by the Ministry of Urban and Rural Construction and Environmental Protection, China Academy of Building Research and relevant units has been reviewed by relevant units. "General Symbols, Units of Measurement and Basic Terms for Building Structure Design" GBJ83-85 is now approved as a national standard and will be implemented from July 1, 1986. This standard is managed by the Ministry of Urban and Rural Construction and Environmental Protection, and its specific interpretation and other work are the responsibility of China Academy of Building Research. The publication and distribution is organized by the Basic Construction Standards and Quotas Research Institute of our Commission.

Preparation Instructions
This standard was prepared by the China Academy of Building Research in conjunction with the management units of the unified standard for building structure design, concrete structure design code, wood structure design code, masonry structure design code, steel structure design code, thin-walled steel structure technical code, civil air defense basement design code, industrial and civil building foundation design code, industrial and civil building structure load code, industrial and civil building seismic design code and China Building Industry Press. During the preparation process, opinions were widely solicited nationwide in various ways. After several discussions and revisions, the draft was finally finalized by our department. This standard consists of four chapters: general principles, general symbols, measurement units and basic terms. It also includes a conversion table between commonly used non-legal measurement units and legal measurement units. Among them, the general symbols adopt the provisions of the national standard "General Principles for Quantities, Units and Symbols" (GB3101-82), and refer to the provisions of the international standard "Basis for Structural Design-Marking Method-General Symbols" (ISO3898); the measurement units are based on the "Legal Measurement Units of the People's Republic of China" issued by the State Council, and adopt the provisions of the "Usage Method of Measurement Units of the People's Republic of China" issued by the National Bureau of Metrology. The meaning of basic terms is explained with modern concepts as much as possible. The meaning explains the main meaning of the term. The English terms corresponding to the basic terms are recommended for use. In the field of construction, it is the first time to compile such a general national standard. Due to lack of experience, there will definitely be many shortcomings. In the process of implementing this standard, please send relevant questions and opinions to the Institute of Building Structures of the China Academy of Building Research at any time for further revision and continuous improvement in the future.

Chapter I General
Article 1.0.1
This standard is formulated in order to reasonably unify the common symbols, measurement units and basic terms of building structure design in my country. Article 1.0.2 This standard applies to building structure design and related fields. Article 1.0.3 The common symbols in this standard adopt the provisions of the national standard "General Principles for Quantities, Units and Symbols" (GB3101-82), and refer to the provisions of the international standard "Structural Design Basis-Marking Method-General Symbols" (ISO3898); the measurement units are based on the "Legal Measurement Units of the People's Republic of China" and adopt the provisions of the "Method for Using Legal Measurement Units of the People's Republic of China".

Chapter 2 General Symbols
Article 2.0.1 The symbols for architectural structure design are composed of the main symbol or the main symbol with superscripts and subscripts. The main symbol generally represents a physical quantity: the superscript and subscript represent the physical quantity or the terms and explanatory words other than the physical quantity, which are used to further express the meaning of the main symbol. Article 2.0.2 The main symbol shall be represented by a letter, and the superscript and subscript may be represented by a letter, abbreviation, number or other mark. Generally, one superscript is used, and one or more subscripts may be used. When more than one subscript is used, they can be arranged in the order of material type, stress state, location, direction, cause, and nature. When the meaning of each subscript is written continuously and may be confused, a comma should be added between each subscript.
When the meaning of the symbol is not confusing, it is advisable to use less or no superscripts and subscripts. Article 2.0.3 Symbols for building structure design shall be selected from uppercase Latin letters, lowercase Latin letters, uppercase Greek letters or lowercase Greek letters according to the provisions of the dimension column in Table 2.0.3.
