Notice on the release of the national standard "Steel Structure Design Code"
(88) Jianbiaozi No. 306
According to the requirements of the former State Construction Commission (81) Jianfashezi No. 546, the "Steel Structure Design Code" revised by the Ministry of Metallurgical Industry and relevant departments has been reviewed by relevant departments. The revised "Steel Structure Design Code" GBJ17-88 is now approved as a national standard. It will be implemented on July 1, 1989. The original "Steel Structure Design Code" TJ17-74 was abolished on January 1, 1991. This code is managed by the Ministry of Metallurgical Industry, and its specific interpretation and other work are the responsibility of the Beijing Iron and Steel Design and Research Institute of the Ministry of Metallurgical Industry. The publication and distribution is the responsibility of China Planning Press. Ministry of Construction of the People's Republic of China

Revision Notes
This code is edited by our ministry in accordance with the notice of the former National Capital Construction Committee (81) Jianfashezi No. 546. It is specifically revised by our Beijing Iron and Steel Design and Research Institute in conjunction with relevant design, scientific research, construction units and colleges and universities across the country based on the "Steel Structure Design Code" (TJ17-74) approved by the former National Capital Construction Committee and the Ministry of Metallurgical Industry in 1974.
This code is divided into twelve chapters and eight appendices. The main contents of this revision are: the limit state design method based on probability theory replaces the allowable stress design method; the application of 15MnV steel and 15MnVq steel is increased; the overall stability coefficient of bending members is adjusted; the relevant formulas for the calculation of the local stability of the web of bending members are added, the stability calculation of axially compressed members adopts three curves, and the stability of compression bending members is calculated by the relevant formulas: the calculation length of multi-story frame columns is increased; the fatigue calculation uses the stress amplitude instead of the stress ratio, the calculation method considering the stress direction is adopted for the right-angle fillet weld in the connection, and the pressure-bearing high-strength bolt connection is added; some contents of the structural requirements are adjusted; the contents of three chapters on plastic design, steel tube structure, and steel and concrete composite beams are added. This code must be used in conjunction with the "Building Structure Load Code" (GBJ9-87) formulated or revised in accordance with the "Building Structure Design Unified Standard" (GBJ68-84) and various national building structure design standards and specifications, and shall not be mixed with various national building structure design standards and specifications not formulated or revised in accordance with the "Building Structure Design Unified Standard" (GBJ68-84).
In order to further improve the standard, we hope that all units will pay attention to accumulating information and summarizing experience in the process of implementing this standard. If you find that there are places that need to be modified and supplemented, please send your opinions and relevant information to the Beijing Iron and Steel Design and Research Institute of the Ministry of Metallurgical Industry (No. 4 Baiguang Road, Beijing) for reference in future revisions.
